  1. I claim that you can find all types of rocks like Igneous and sedimentary. Rocks even Igneous rocks can be found, Sedimentary rocks are most common and wouldn’t be to hard to find, Metamorphic rocks can also be found since a Sedimentary can become a Metamorphic rock, and lastly a Igneous rock is questionable but could be found from the earth’s interior.

    • I claim that you can find any type of rock like Igneous,Sedimentary, and Metamorphic in Minnesota. My evidence is that i looked at a geological map of Minnesota. Every rock can turn into any other rock like how Metamorphic can both be Igneous and Sedimentary and same goes to the other two rocks. A rock can change into another rock by many steps like how a Sedimentary rock can be melted (by either a volcano or heat from the center of the earth) and turned into a igneous rock. Different types of Igneous,Sedimentary, and Metamorphic can be found in Minnesota is because these rocks can change which means it can spread different types of rocks from changing. I think a type of rock would’ve already been there (Metamorphic or Sedimentary probably because igneous needs heat to form and we don’t have volcanos) and started to change to make other varieties of rocks.

    • I now claim that all Igneous, Sedimentary, and Metamorphic rocks are in Minnesota due to the map we found. A lot of Igneous rocks are in the North NE and NW. Many Sedimentary rocks are in the South SE and SW. Most Metamorphic rocks are found in both North and South of Minnesota. The reason why they somehow ended up here is because Sedimentary rocks can turn into Metamorphic rocks. Sedimentary rocks come from heat and pressure along with chemicals all being compressed together to form the rock. It can also be possibly chipped off from a bigger rock. Igneous rocks is really confusing on how they get there but it does come from either the earths interior or maybe they were just formed in Minnesota but were rare to find.

  2. I think the kind of rocks found in Minnesota are mostly sedimentary. The layers of sediment builds up and compacts and cements to form rocks. Sedimentary rocks come in all forms, shapes, and sizes. They can also form from erosion and break down to smaller rocks.

    • i claim the you can find igneous rocks but that would be very hard to do considering that we dont have any volcanoes that we know of. you are more likely to find sedimentry since we have a lot of soil.

  3. I believe that few to little igneous rocks are in Minnesota due to the fact that we have no volcanoes. I think you will find quite a bit of sedimentary, but less metamorphic. Although metamorphic would still be present.

  4. I claim that most of the rocks are Sedimentary and Metamorphic. I believe this because sedimentary rocks are made be weathering and metamorphic rocks are made by other rocks by heat or pressure.

    • I claim that there are all types of rocks in Minnesota. My evidence is, for igneous rocks there could have been a volcano close by that created these rocks and left them to sit there for years and never really moving much. The sedimentary rocks could be from igneous, metamorphic, or other sedimentary rocks breaking off then start to get layered and cemented together. Lastly, for the metamorphic rocks some of the igneous or sedimentary rocks underwent heat or pressure to make metamorphic rocks.

  5. I claim that you can find all rocks but different types in different places. You might find metamorphic or sedimentary but. I don’t think you can find igneous because we don’t have volcanoes or stuff like that

    • I claim that you can find all the igneous-metamorphic sedimentary in minnesota because. We looked at a map and found that igneous rocks can be formed underground or in a volcano which we don’t have here in Minnesota. Metamorphic can all be seen in Minnesota. By compacting under the ground with heat and pressure and those rocks can be eroded and turned to sediment. And can be put under heat and pressure to become a sedimentary rock.

  6. I claim that rocks from Minnesota are sedimentary since we have no volcanos that make igneous rocks and I mostly see sedimentary rocks.

  7. I think that the sedimentary rocks are the most commonly found rocks, but there can be all types of rocks in Minnesota. Each type can become another with differing changes, and throughout many years, there has been a lot of changes in our climate and conditions.

    • I think that you can find all of them in Minnesota. Sedimentary Rocks form when other rocks are weathered and erode because of wind, water, or ice, and then compacts and cements together. Any rock can become a Sedimentary Rock. Metamorphic Rocks form when heat and pressure are applied to the rock, like the Sedimentary Rock, any rock can become a Metamorphic Rock. Igneous Rocks are formed when magma cools/hardens, but the rocks can form on the Earth’s surface, or beneath it. When it is formed beneath, it cools slowly and grows large crystals. When it is formed on the Earth’s surface, it cools very fast, and has small crystals. Like the Metamorphic and Sedimentary rocks, any rocks can become Igneous.

  8. I claim that most of the rocks in Minnesota are Sedimentary and possibly Metamorphic because Sedimentary rocks are formed by weathering and erosion and due to the land we have in Minnesota it might be the right conditions.

    • I claim that you can find Igneous, Sedimentary and Metamorphic rocks in Minnesota. Our class had the chance to look at a geological map of Minnesota and it showed all the different types of rocks. Igneous rocks were found more in the NW such as basalt, graywacke and slate. Igenous rocks were on our map but not as common because we do not have any Volcanoes. Metamorphic rocks which are common in all parts of Minnesota were from the tectonic plates in the Great Lakes region. Metamorphic rocks such as schist, quartzite and gneiss.
      Sedimentary rocks are caused by erosion from our lakes and rivers, Sedimentary rocks like mudstone, limestone, dolostone and shale.

  9. I claim that sedimentary rocks would be more common to find in Minnesota other than igneous because we have no volcanoes. Metamorphic rocks could probably be found but not as much as sedimentary.

    • I claim that Sedimentary rocks, Igneous rocks, and Metamorphic rocks could all be found in Minnesota. My evidence is igneous rocks were moved by glaciers. Minnesota has sedimentary rocks that were most likely formed by lakes and rivers. Some sedimentary rocks that can be found in Minnesota are graywacke and mudstone. Metamorphic rocks can be found in Minnesota because there is a hot spot in that area a couple examples are quartzite, gneiss.

    • I claim that all the rocks are found here in MN. Like sed. metamorphic, igneous rocks. I looked at a geographic map and it looked like sed. rocks were in the middle and igneous are on the top, and meta. we’re found in the bottom. I think where they were found it was the climate because in some parts of MN it’s hot and could be cold.

  10. there are many types of rocks but most of the time their split into simply three categories ingenious, sedimentary, and metamorphic which can all be found here
    -ingenious rocks are formed from magma.
    -sedimentary rocks are rocks broken or chipped off from a larger rock or structure.
    – and the last category of rock s metamorphic which consist of both the previous categories of rock but when it is metamorphic that means it has been changed by heat and pressure.

  11. I claim that all types of rocks can be found in Minnesota just not specific kinds. There’s probably a lot of sedimentary rocks and metamorphic but there might not be as much igneous rocks.

    • I claim that igneous, metamorphic, and sedimentary rocks are all found in Minnesota. My evidence is a geological map that we looked at in class of the rock types found all over the state. The map had many different types of rocks and where they were on the map.

  12. I think all rocks are found in Minnesota because the earth is the same as all the other continents. Why wouldn’t there be the same rocks as there is in florida.

  13. I claim that sedimentary rocks are found more in Minnesota because they are basically just rocks piled and pressed together to make a new form of rock. The metamorphic rock would not be as common, because in order for them to form, there would have to be heat, pressure, and some sort of chemical action. As well as the igneous rock.

  14. I claim that all varieties of rocks (Sedimentary, Metamorphic, Igneous) are found in Minnesota. My evidence is that the different kinds of rocks you can find just lying in the dirt and on the ground. I claim that most of the rocks we find are metamorphic because there are lots of little rocks that we can find that may have come from another rock. Sedimentary rocks are also very common but I’m not entirely sure if igneous rocks are very common in Minnesota. I believe there is more Sedimentary rock in places where there are bigger landforms like mountains. I believe these types of rocks are in Minnesota because there are not too many very large landforms and theres more soil.

    • My ideas have changed. I claim that Igneous rocks and Sedimentary rocks are commonly found in Minnesota and our most common rocks are, Greenstone, sandstone, siltstone, and shale. My evidence to this is the map I colored and the map and the map of the simplified bedrock Geology. We have Metamorphic rocks in Minnesota but not very much, that’s because of the climate and the land and soil type. Minnesota is cold most of the time because it is up north and the climate affects rocks and erosion to the connection of the water cycle, and we have so much precipitation so rocks can weather over time. The soil can also affect rocks because in the ground the rock weathers over time. The rock can break down into other rocks.
      Igneous and Sedimentary rocks can be formed into Metamorphic rocks by pressure and heat. We most likely have more Sedimentary rocks than Metamorphic and Igneous rocks because we have the land in the north for it, there is not really any mountains and such.

  15. I think most rocks are sedimentary rocks because of all of the snow, rivers, and lakes. most landforms are probably lakes because the nickname for Minnesota is land of 10,000 lakes and glaciers most likely stopped here.

    • I claim that all types of rocks, such as sedimentary, igneous, etc. are found in Minnesota. my evidence is my Minnesota map. it explains that all rocks are found in Minnesota. Sedimentary are probably from rain and snow, metamorphic most likely come from the mountains and igneous rocks were most likely pushed up by the glaciers.

  16. I think that there are more sedimentary rocks found in MN because of all the rivers. Rivers carrie rocks and at the end of a river, the rocks become sedimentary. Since we don’t have any volcanoes around here, we probably won’t have many natural igneous or metamorphic rocks.

    • I think that Minnesota. has mostly sedimentary rocks, due to the amount of rivers and lakes carrying rocks, which then are compact into sedimentary rocks. We also have some igneous and metamorphic rocks, even though there isn’t a volcano near by. I think they were carried by glaciers or clouds.

  17. I claim that all three types of rock can be found in MN. My evidence is basically What I think is that all three types of rock can be found anywhere Igneous, metamorphic, and sedimentary rock.

    • I claim that you can find all three types of rock igneous, sedimentary and metamorphic rock but only some like we have schist, limestone, greenstone etc and I think these types of rocks are found here sedimentary rock is found by the mountains with all the minerals. Wha I think metamorphic rock is found in Minnesota because the crystals are formed together to create metamorphic rock. Also igneous rock is formed in Minnesota by maybe heat helped make the igneous rock. My evidence is my Minnesota map from google classroom.

    • I claim that you can find all three types of rock igneous, sedimentary and metamorphic rock but only some like we have schist, limestone, greenstone etc and I think these types of rocks are found here sedimentary rock is found by the mountains with all the minerals. Why I think metamorphic rock is found in Minnesota because the crystals are formed together to create metamorphic rock. Also igneous rock is formed in Minnesota by maybe heat helped make the igneous rock. My evidence is my Minnesota map from google classroom.

  18. I claim that mainly only sedimentary and metamorphic would be found my evidence is that there are no current volcanoes in Minnesota which could contribute to making igneous rocks, which means they would have to be made way before settlement in Minnesota (millions of years). Sedimentary could be easily found as it is the most common and metamorphic can be formed from sedimentary and vice versa.

    • I claim that sedimentary, metamorphic, and igneous rocks can all be found in Minnesota. My evidence is supported by geological maps of Minnesota that show the rocks and landforms and where each can be found, based on the evidence of the maps sedimentary seems to be the most common rock found within Minnesota.
      Many rocks found in Minnesota have most likely be here for many years some spanning millions and others hundreds or thousands, they have most likely been form from bigger rocks that have suffered from erosion due to the harsh winters and weathers in the summer.
      Most of Sedimentary rocks include mudstone, limestone, sandstone, greywacke, and iron-formations. Igneous rocks include Volcanic rocks, intrusive rocks, greenstone, and granite. Metamorphic rocks consist of Gneiss, Schist and iron-formation, Schist, and Quartzite. All of these types of rocks and the certain kinds can be found in various regions of Minnesota.

  19. I think the most common rock is sedimentary rock because thats the only rock that can really form in Minnesota. igneous rock needs a volcano and metamorphic rock need heat and pressure

    • The most common rock in Minnesota is probably sedimentary because it just broken down pieces of rock and sand. Metamorphic rock can be in Minnesota too because sedimentary rocks can overtime change to metamorphic rock with heat and pressure. There is probably a little amount of igneous rock too from inside earth, but the most common rock in the state of Minnesota is most likely sedimentary rocks.

  20. I claim that sedimentary, igneous, and metamorphic rocks are found in Minnesota. My evidence is that metamorphic rocks only need heat and pressure so they can be found all over. Sedimentary rocks can be found in Minnesota, because of all our lakes and rivers. Also, wind erosion can carry the particles here. Finally, another reason these rocks can be found here is glaciers dragged rocks all over.

    • I claim that sedimentary, igneous, and metamorphic rocks are found in Minnesota. My evidence is that we have igneous rocks that were moved by glaciers here like basalt, greenstone, granite, and gabbro. Also, Minnesota has quite a bit of sedimentary rocks that were very likely formed by our lakes and rivers. A few examples of sedimentary rocks that can be found in Minnesota are mudstone, limestone, sandstone, and graywacke. The final type of rock that can be found in Minnesota are metamorphic rocks. Metamorphic rocks can be found in Minnesota, because there happens to be a hot spot in that area a few examples are gneiss, schist, and quartzite. Those are the reasons that sedimentary, igneous, and metamorphic can be found in Minnesota.

  21. I claim that there can be a variety of different rocks. There can be sedimentary rock or there can be metamorphic rock it just depends on where you look.

    • I claim that all different types of rocks are found in Minnesota like igneous metamorphic and sedimentary and my evidence is that throughout Minnesota all different types of rock like Valspar and quartz because that in Minnesota you can find all of rocks. Like when you find igneous rock it maybe hear because it was made deeper in the earth and over time they were pushed up.

  22. I think that all three of the kinds of rocks could be found in Minnesota. Sedimentary rocks seem to be the most common because of the lack of volcanic activity in Minnesota, rocks such as Igneous and Metamorphic rock could still be around because maybe they were brought up by people or glaciers scraping the land.

    • I claim that Metamorphic, Igneous, and sedimentary rocks can all be found in Minnesota. My evidence is that a geological map of Minnesota shows the there is evidence of all the kinds of rock in the land. In the map it shows that the rocks are not that diverse throughout the state, Igneous rocks are located in the northwest of the state, Sedimentary rock is located every were in the state, and Metamorphic rock is also located throughout the whole state. How these rocks may have arrived here in Minnesota is They may have traveled through rivers because of the amount of rivers and lakes we have here, the rocks could also be thousands of years old from when glaciers had covered most of Minnesota and had scraped up other rocks from a different area and was dropped in Minnesota.

  23. I claimed that the rocks that are found in Minnesota are Metamorphic, Igneous and Sedimentary rocks. Rocks are found in Mountains, soil, lakes, and beaches.
    My evidence is they are found here possibility that they came from the glaciers. I have seen rocks at beaches, sidewalks, roads. I know that all rocks can become a different type of rock so I think that’s why they are all found in Minnesota.

  24. I claim that the kinds of rocks that are found in Minnesota are Sedimentary and Metamorphic rock because Metamorphic they are made by heat and pressure, and Sedimentary because Minnesota rarely has volcanos.

    • I claim that igneous rocks, sedimentary rocks, and metamorphic rocks are found in Minnesota. For the igneous rocks there are volcanic rock the most of that rock is basalt, intrusive rocks gabbro and anorthosite is what is in Minnesota mostly. Greenstone there is also greywacke and slate, and lastly granite. For the sedimentary rocks there are mudstone, siltstone, sandstone, limestone, dolostone, shale, greywacke, and iron-formation. For metamorphic rocks there are gneiss, schist, iron-formation, and quartzite. My evidence is the Minnesota map that shows me the types of igneous rocks, sedimentary rocks, and metamorphic rocks that are found in Minnesota. I think the igneous, and metamorphic rocks were from glaciers and the sedimentary rocks were formed by lakes and rivers that are in Minnesota.

  25. Blog 2 Minnesota rocks
    I claim that a variety of rocks can be found in minnesota like shale,limestone and basalt. And I think there would be a lot of sedimentary rocks found and maybe a little bit of metamorphic rocks but not very much igneous rock

    • I claim that that different types of rocks are found in Minnesota like granite,mudstone and gneiss.Limestone is sedimentary rock which means it is heavily compacted. Granite is an igneous rock because it is formed under intense heat and pressure, slate is a metamorphic rock because it undergoes different types of phases in which it can form like chemical reactions heat and pressureSedimentary could have come here from numerous layers of sediment being broken over time they are located in northern Minnesota .Igneous rocks might have been formed from a long dormant volcano. And metamorphic rocks were formed in shallow inlands billions of years ago they are found in southwestern Minnesota

  26. I think that metamorphic and sedimentary rocks are the most common in our area, as they are the most common around the world. As sedimentary rocks make up 75% of our Earth is is quite sensible that Minnesota could have many of them. Igneous rocks are much rarer, as there are no active volcanoes in Minnesota, but there are still some along the North Shore. Metamorphic rocks like slate and marble are still very abundant across Minnesota.

    • I claim that all rock types are found in Minnesota. Igneous rocks are found in the forms of basalt and granite. Metamorphic rocks like slate and gneiss are common in all regions of Minnesota. Lastly, sedimentary rocks are plentiful everywhere. These include graywacke and other common rocks. My evidence for this is the map our class was given. It showed the distribution of the most common Minnesota rocks. I think these types of rocks are found here because of the natural geology of Minnesota. Sedimentary rocks are caused by erosion from our many lake and rivers, while metamorphic rocks can be brought here from tectonic plates such as in the the Great Lakes tectonic zone. Igneous rocks could be caused from volcanic eruptions elsewhere, which could also be brought the same way as metamorphic rocks.

  27. I claim that metamorphic rocks and sedimentary rocks can be found in Minnesota because metamorphic rocks are made by heat and pressure underground and sedimentary rocks are made of sand mud and pebbles in rivers and lakes. I do not think there are igneous rocks in Minnesota because we do not have volcanoes and there is really nothing for a igneous rock to be made here.

    • I claim that sedimentary, igneous and metamorphic rocks are found in Minnesota.
      My evidence is that by looking at a bedrock geology map there is more sedimentary rock near the center of Minnesota because there is a lot of mudstone, siltstone, sandstone, shale, limestone and dolostone near the center of Minnesota. sedimentary rocks are found here because there is sand, mud and pebbles in Minnesota. Metamorphic rocks are found near the center and the edges of Minnesota because there is heat and pressure underground that is making rocks into metamorphic rocks. Igneous rocks are not commonly found in Minnesota because there are no volcanos here.

  28. I think you can find sandstone, limestone, mudstone, Quartzite and Shale. From my experiences from farming in southern Minnesota these are the ones that we found down there. I am sure there are more but I don’t know them. I do believe that their are all of the three types of rocks in Minnesota.

  29. I claim that there are igneous rocks, sedimentary rocks, and metamorphic rocks in Minnesota. There are sometimes crystallized rocks. My evidence is that in the rock cycle the three types of rock can change into a different type of rock. Because Minnesota has rivers, lakes and lots of natural land then the rock cycle can happen.

  30. Minnesota rock blog
    I claim that there are metamorphic rocks in MN. My evidence is that you can see a lot of the metamorphic rocks on the earth surface like dirt roads.I think that there are igneous and my evidence is dig down deep enough you could probably see some igneous rocks if you’re lucky.

    • I claim that there are 3 different types of rock in Minnesota, igneous, sedimentary and metamorphic. There is more sedimentary than igneous and metamorphic. My evidence is that these different rocks are in different areas of Minnesota and if you look at a Minnesota map of bedrock geology you can find all the different places and all the different rocks there. Around the middle of Minnesota is where most of the sedimentary rock is found. Down near the bottom of Minnesota some sedimentary, mostly limestone. Near the top is where hardly any sedimentary rock is but others like greenstone, schist, limestone and granite. Metamorphic rock is found in the south west of the state in the form of quartzite. By looking at the map I can see that there is not very much igneous rock. This is because igneous rock is formed under heat and pressure and in volcanos. Minnesota does not have any active volcanoes but may have in the past, that’s how there are some igneous rocks here.

  31. I claim that minnesota was made out of glaciers. My evidence is that over time the glaciers melted away and left rocks and soil which was then part of the rock cycle. The way how the land formations was formed is by things like river and mountains. A part of the rock cycle is when lakes are formed by at the bottom of the lake it is pushing pressure on the bottom of the lake and that is what make the lake deeper.

  32. I claim that Minnesota has a little bit of Igneous rocks because we do not have volcanos in Minnesota. You can also find sedimentary rocks in some places and sedimentary rocks are formed by weathering and erosion which we might have in Minnesota. Metamorphic rocks may not be able to be found in Minnesota because they are formed by heat and pressure.

    • I claim that you can find find some (Metamorphic, Sedimentary, and Igneous) of each rock in Minnesota. My evidence is on the Minnesota map, on the northside of Minnesota you can mostly find igneous rocks and in the south side you can find metamorphic and sedimentary rocks. I think that sedimentary rocks were formed by rivers and lakes in Minnesota, for metamorphic and igneous were made by glaciers.

  33. I claim that you can find find some (Metamorphic, Sedimentary, and Igneous) of each rock in Minnesota. My evidence is on the Minnesota map, on the northside of Minnesota you can mostly find igneous rocks and in the south side you can find metamorphic and sedimentary rocks. I think that sedimentary rocks were formed by rivers and lakes in Minnesota, for metamorphic and igneous were made by glaciers.

  34. I claim that there are igneous rocks, sedimentary rocks, and metamorphic rocks in Minnesota. My evidence is that most rocks in minnesota come from underneath the ground. And that they sometimes come from a volcano from the ground. Most igneous rocks are from the shoreline of Lake Superior. The most common sedimentary rocks are are sandstone, limestone, and shale. The two common metamorphic rocks are shale and marble. Metamorphic rocks in Minnesota are found in Duluth and Minneapolis. Sedimentary rocks are found in southern Minnesota, like in the twin cities.

  35. I claim that you can find all the rocks in Minnesota. Because there might have been brought some volcanic rocks to Minnesota or. There was one here millions of years ago and there could be underwater volcanoes or. Some that don’t work anymore and the other types of rocks like metamorphic can all be seen in Minnesota. By compacting under the ground with heat and pressure and those rocks can be eroded and turned to sediment. And can be put under heat and pressure to become a sedimentary rock.

  36. I claim that the rock types that can be found in Minnesota are sedimentary and metamorphic as well as igneous rocks but there are not as great amounts of igneous rocks because there are no volcanoes in Minnesota and igneous rocks are created through heat from magma and pressure however evidence shown on the maps that we used in this activity you could find them in the north. So sedimentary and metamorphic can be found just about everywhere in Minnesota while igneous can be found on really only on the north side of it.
