    Minnesota’s landforms and rocks I don’t know much about them but while I’m walking around I’ll look at rocks and there are many different seeming rocks they are small but then very large but the small ones have a more earthy smell and different looks to them and the large ones I’ve seen those around the iron range and by Lake Superior they were very large rocks and they can have are earthy smell and long with a water salty kinda smell and some fiery smell like burnt toast but that’s my opinion.

    Sedimentary rocks are sandstone, limestone, shale, and Igneous. Metamorphic rocks are igneous or sedimentary rocks which have been changed by heat or pressure. And igneous rocks. There are shiny rocks, dull, heavy, light. There’s a lot of different types of rocks in Minnesota.

  3. Emily says:

    I know that when we went to camp miller we got to go rock climbing on limestone and sandstone.

    • Emily says:

      I claim there are many different rocks in Minnesota and they can be found in different areas. Sandstone is a sedimentary rock that can be found in layers where oceans or lakes used to be. Just like basalt is near lake superior which that is volcanic rock. Limestone is also in Minnesota because of lakes or a body of water. There are also erratic rocks that are not from here. My evidence is that when glaciers were in Minnesota they brought rocks that are not native to Minnesota. I also know that sedimentary and limestone is here because I saw it when I went to Camp Miller.

  4. Raven says:

    I’ve never really researched anything on Minnesota rocks or landforms but I do know that we have sandstone and limestone because of camp miller also those huge dark colored rock by Lake Superior when I went on the Lake Superior hiking trail trip other than that I don’t know much.

    • Raven says:

      I claim that sandstone, limestone and basalt can be found in Minnesota my evidence is that I saw them on my Lake Superior hiking trip, sandstone and limestone are often found by water which is how it becomes compress by the pressure of the water and turns into a sedimentary rock while basalt is a igneous rock and is also found by lake superior and is a volcanic rock.

  5. caitlynn says:

    The most common rocks I’ve seen are sedimentary rocks, sandstone, limestone, shale, and conglomerates. Not really any others I’ve seen there could be more kinds

  6. Dante says:

    I don’t know that much about types of rocks or minerals but when I was on my hiking trip i seen basalt and that’s a volcanic rock.

  7. alec says:

    The only thing I know about our minnesota monuments is when i went to camp miller and climbed a limestone and sandstone wall

    • alec says:

      I claim that rocks were pushed by glaciers into Minnesota. My evidence is that this happens with sedimentary rocks. The under ice rocks and boulders were being moved around.Gravel and sand are being plowed and scraped across the ground like a bulldozer.River and streams flow through the ice to push any left over rocks to were they could be pushed over again.

  8. Jestin says:

    Minnesota’s landforms are mostly lakes as the quote for Minnesota “The state with 10,000 lakes”. And in Minnesota (mostly the world) the most rocks here is Limestone, We also have Marble and Rock salt and Iron with some Flint. Minnesota’s 2nd landform is plains and that’s why most of Minnesota has Wheat fields on the plains.

  9. Megan says:

    I don’t know that much about Minnesota’s rocks and landforms, but I do know a little bit. In Ely, there is a lot of iron ore because the Soudan Mines was the Cadillac of mines for iron ore. On the north shore, there is a lot of limestone, sandstone, and basalt.

    • Megan says:

      I claim that there are many kinds of rocks in Minnesota and they came from many places. My eveidence is that there is coal, limestone, sandstone, basalt, and iron ore. The coal in Minnesota actually came from Canada. Eskers are rocks that came from other places because glaciers have carried them into Minnesota. Under the Earth’s crust in Minnesota there is many types of igneous rocks such as granite, there is also sedimentary rocks because there is a lot of lakes and water in Minnesota so there is a lot of erosion, such as sandstone. There is metamorphic rocks in Minnesota as well that are deep in the earth’s crust such as marble.

  10. neal says:

    The rocks and landforms come from the rain and rivers they pick up rocks and move them to a different location. The rivers can change the landform by washing away the minerals bit by bit it will take a lot of years to do this. And at lacks will have lakes to watch the sand on the shore and move it down a river that go throw that lake. The rocks are formed by magma and go down a river and moves to Minnesota. The rain will have minerals that will end deep in the eath and form a rock will move up to the at Minnesota.

    • neal says:

      I claim my evidence because i know that the glaciers are the caose od the landform and rocks the ended up at MN. almost all of Minnesota was covered in a glacier wish meltidi and moved from the glaciers which the rocks and scrape out the ground which made the lakes in Minnesota. All the racks were left in Minnesota came from canidu wich glasherst are pickit up by them lick a cuvalu belt. Bring the rocks all the way to Minnesota the glaciers melt in Minnesota and the racks are in the glaciers. Some of the rock in MN are igneous rocks because there warh volcanoes and sedimentary rocks.

  11. Trey says:

    Minnesota has a few different kinds of rocks like limestone and I’m guessing that they came here with glaciers and ice.

    • Trey says:

      I claim that Minnesota has many kinds of rocks like igneous, sedimentary, and metamorphic and they came here with glaciers. My evidence is that glaciers used to cover all but southwest Minnesota. The glaciers would melt at the end and freeze at the beginning and act like an upside down conveyor belt and bring rocks from all over Canada and northern areas and dump the rocks in Minnesota.

  12. Mason says:

    The rocks I belive are around minnesota are sedimentary becouse of our winters can carry minerals the forms layers around the other layers and in spring the winters wet snow will brake up the stones makeing rocks!

    • Mason says:

      Most of the rocks that come from other places came from the glaciers and “how does a huge block of ice bring rocks from upper Canada all the way to Minnesota?” you may ask, well when the ice froze the rocks on the ground would freeze the rocks, and the glacier would move by the ice melting on the bottom and re-freezing on the top. it causes the ice to move and when the glacier moves it unfreezes at the back and re-freeze at the front the rocks trap it the ice will slowly be release back it a new place. right now my topic is “rocks in MN” so I’m just going to stick with MN. That’s how rocks made it’s way to MN!

  13. Vera says:

    I think in Minnesota we have the same igneous, sedimentary, and metamorphic rock as anywhere else. Igneous rocks are made from magma, sedimentary are made from sediment in the water, and metamorphic rocks are made from heat and pressure from when they’re in the ground.

    • Vera says:

      I claim the Minnesota has the same sedimentary rock, Igneous, and metamorphic rock as anywhere else. My evidence is that glaciers covered all of Minnesota, and as they moved they would pick different things like rocks called remnants. As they started to move and melt all of those rocks and things that were in there came out of the ice. The reason why I think we had all of the types of rocked is because not only was Minnesota covered but Canada was too, so the glaciers probably picked up those rocks too bringing them to Minnesota.

  14. matt says:

    I think that the rocks we have here where dragged down by glaciers from Canada. I also think that we have sedimentary or metamorphic because I’ve seen layers on the rocks.

    • matt says:

      I claim that sedimentary, igneous, and metamorphic rocks were dragged down to Minnesota by glaciers. My evidence is that glaciers used to cover all of Minnesota and Canada except the southwest corner of Minnesota. Glaciers melted from friction and froze with rocks in them and brought them down to Minnesota then melted.

  15. Hailey says:

    I think that Minnesota has the same types of rocks as most places do. Minnesota probably has sedimentary rock, igneous, and metamorphic rock. Sedimentary rock is created when sediment, which is made up of loose pieces minerals, is put under a great amount of pressure while getting buried new layers of sediment which are later deposited. As the sediment gets compacted and cemented together it creates sedimentary rock. Igneous rock is formed when magma crystallizes on or underneath the Earth’s surface. The last type of rock is metamorphic rock which is formed when a rock is put under extreme heat and pressure that new minerals grow in the rock at the expense of some of the original minerals. Some rocks that I know of that are in Minnesota would be sandstone, limestone, shale, granite, basalt, and slate.

    • Hailey says:

      I claim that there are many different types of rocks in Minnesota and that they can be found in many different areas. My evidence is that since sandstone, which is a sedimentary rock, is found in many places where lakes used to be. For example, you can usually find limestone by bodies of water or lakes, but sometimes they’re not by a source of water at all. When the glaciers traveled across Minnesota and melted from friction, they filled deep gouges in the Earth which filled up to become the enormous lakes we recognize today. As these lakes evaporated or withered, many remnants of these lakes stayed in place. Limestone may be one of these remnants. There isn’t just sedimentary rock like limestone instead there are igneous and metamorphic rocks in Minnesota too! Like basalt for example, which is a volcanic rock that you can find right near Superior Lake. There are also many erratic rocks that aren’t native to Minnesota. You see when the Glaciers moved across Canada and other places they carried rocks, clay, dirt, and other materials to Minnesota which caused these non-native rocks.

  16. Sarah says:

    I don’t know much about Minnesota’s rocks but I do know that some must be sedimentary because we have so many lakes and so much water that they could cement in to form. We could also have some rocks from glaciers coming down from Canada

  17. michael says:

    the rocks up here I know that are limestone, sandstone but the other one I have is they came down here with ice and glacier’s that’s all i know

  18. Duran says:

    I didn’t really pay attention to rocks, but I am pretty sure that we have sedimentary, metamorphic, and igneous rocks.

    • Duran says:

      I claim that Minnesota has only sedimentary rocks and metamorphic rocks. My evidence is that when the glaciers came down here, they pushed those rocks that got under them to us. The glaciers had a material called till that depressed the land under it, and because of that, we have many lakes and rivers that the rocks could form in. I say that there is no igneous rock because there is no volcano near or in Minnesota to form them.

  19. pamela says:

    In Duluth, Minnesota there are agates. The type of rock would have to be sedimentary. we have a lot of lakes in MN so sediment that is in the lakes can form the rocks.

    • Pamela says:

      I claim that the rocks in Minnesota are sedimentary rocks. My evidence is that sedimentary rocks form by water. Minnesota has a lot of lakes including Lake Superior. Some of the rocks that are in Minnesota didn’t form in Minnesota. Once glaciers covered most of Minnesota. The glaciers would move rocks down from Canada or somewhere farther north would come down to Minnesota. For example, the iron from the iron range in Minnesota is from somewhere in Canada.

  20. olivia says:

    The most common rocks I’ve seen in Minnesota are sedimentary rocks, sandstone, limestone, shale, and conglomerates. I haven’t really seen the other kinds of rocks around but maybe Duluth has them.

  21. adrianna says:

    the most common rocks I’ve seen in Minnesota are sedimentary rocks such as sandstone, limestone, shale, and conglomerates. I don’t really see any other kinds but maybe in more places in lakes there could be more rocks other than sedimentary.

  22. Damian says:

    All three types of rocks (sedimentary, metamorphic, and igneous) are found in Minnesota and sedimentary rocks are the most common rocks found. The most common sedimentary rocks found are limestone, shale, sandstone, and conglomerates. When I walk around, I take in all of the scenery and notice the rocks, I don’t pay attention much but now they seem more important. Knowing the rocks, the type and minerals the rock is made from, make them pop out more, knowing all the rocks have a difference, either in the way the rocks are made or from the minerals the rocks contain. Most rocks could have been made in the area it was found in or it could have come from a whole different area, like when Pangea was still the supercontinent, all the rocks we see today could have been made anywhere, it the rock is that old.

    • Damian says:

      I claim that all types of rocks are found in Minnesota and sedimentary rocks are the most common ones found. My evidence is that most of the rocks, from wind erosion, found on the surface are sedimentary rocks. Most rocks may not have been made in Minnesota, since there were glaciers about 10,000 years ago, bringing rocks, plant, and minerals(remnants) to Minnesota. All the rocks and plants were brought here from Canada from the Glacier period.

  23. Carlos says:

    Most of the rocks in Minnesota are sedimentary and or metamorphic because there aren’t volcanoes near Minnesota

  24. Caden says:

    I don’t know much about rocks in Minnesota but a guess would that there are a lot of sedimentary rocks because of all the lakes, and rivers with a lot of sediment on the bottom of them making sedimentary rock. Maybe some other rocks came from a glacier that pushed a lot of soil to Minnesota.

    • caden says:

      I claim that rocks in Minnesota are igneous and sedimentary rocks. My evidence is that the many lakes and rivers could have had a lot of sediment build up in the bottom of them compacting into sedimentary rock. Also sedimentary and igneous rock could have come from Canada. This rocks would have been formed in Canada where glaciers would have frozen around it or it would have been pushed to Minnesota. These are called remnants.

  25. isaac says:

    Most of the rocks in Minnesota are sedimentary, such as limestone and shale and obviously lots more, I also think there is metamorphic.

    • Isaac says:

      I claim that most of the rocks in Minnesota are mostly sedimentary and some are metamorphic too. My evidence is that rocks are found sometimes maybe at the bottom of rivers or lakes or ponds, and at the bottom of lakes and rivers there is a lot of sediment built up there that could compact and turn into sedimentary rock. I also think that glaciers moved most of these rocks down from Canada a long time ago. People say that there are igneous rocks here, but there no volcanoes around Minnesota.

  26. alex says:

    I don’t really know well anything about rocks and monuments but what i do know is that mt rushmore is mostly granite. 🙂

  27. david says:

    I claim that we would have mainly sedimentary rocks in MN my evidence is that we have a lot of large bodies of water

  28. Amadeo says:

    I claim that we have all 3 kinds of (igneous, metamorphic, and sedimentary) rocks in Minnesota. My evidence is that there is a lot of dirt and sand in Minnesota so it’s only logical that there is some sedimentary rock underneath that. Also there is rock that does not sedimentary rock in Minnesota so that means there is either metamorphic rock and/or igneous rock in Minnesota, it’s also exceedingly unlikely that the non-sedimentary rock is all of just igneous or just metamorphic rock. There are also samples of all 3 kinds of rock at Treknorth jr. and Sr. high school.

  29. Samuel says:

    Minnesota is home to not very dazzling rock formations but rock formations all the same. Usually involving water flowing over the rocks or pillars. Minnesota musta been a very glacier riddled to create all of our wonderful lakes.

  30. david says:

    I claim that any kind of rock could be found in MN my evidence is that if glaciers moved across the state, they could drag and drop any kind of rock all over the state. Another reason is that some rocks (not always sedimentary) could have been pushed up the mississippi river and deposited on shore. Also people could bring them here and use them for buildings and decoration.

  31. Nevaeh says:

    I claim landforms in Minnesota are like most and they were made of little bits as the glaciers melted my evidence is that they are formed and moved and placed by the glaciers that had once covered minnesota and now you look at it we have vast areas of ridges and rocks hills and valleys. The types of rocks we have are granite,sedimentary,igneous and metamorphic which can be found all over MN. Lakes are what is left of the glaciers and they “covered all of Minnesota” well that’s a lie the southwest corner wasn’t cover by it and if you think Minnesota was like a big frozen lake and sooner or later they had melted an disappear like magic this had happened millions of years ago we called i the ice age which i believe stuited it very well.

  32. Isabelle says:

    I claim that there are 3 different types of rocks in Minnesota. (Igneous, Sedimentary, and metamorphic). My Evidence is that it’s sandy in minnesota so like it makes sense that there would be those 3 types of rocks in Minnesota. I don’t really know where they came from or maybe when glaciers moved across the state it could of dragged or dropped all over the state.

  33. adrianna says:

    I claim that glaciers are the reason we have so many different types of rocks in Minnesota. My evidence is that rocks are made up of many different minerals and crystals combined. The three basic kinds of rocks are igneous, metamorphic, and sedimentary. All varieties of all three of these rocks can be found in Minnesota because they were remnants from the glaciers that had once covered most of Minnesota. When glaciers were here they had carried broken rocks and soil debris from far from here as they slowly moved across the earth carrying rocks and minerals to Minnesota and leaving behind remnants that had come from places far from here. The only area in Minnesota that wasn’t covered by glaciers was the Southwest corner of the state.

  34. olivia says:

    I claim that there are sedimentary rocks, in minnesota. My evidence is that they are piled layer upon layer and pressed or cemented together to form a new kind of rock. The most common sedimentary rocks are sandstone, limestone, shale, etc. They came from glaciers moving, while the glacier is moving and other piles of sand, pebbles, and rocks left along the way as the glacier moves is called ground moraines. Which is where all the rocks came and came from.

  35. Samuel says:

    I claim that the rock formations of Minnesota were formed by glaciers. My evidence is That the iron ore in Minnesota was formed in Canada and was pushed all the way from Canada by the glacier into minnesota, and some rocks that currently sit in MN have been classified as formed in Canada and were carried here by the glacier. As the glacier moved and melted and refroze, pebbles and rocks became trapped in the ice and as the glacier moved, it scratched and gouged out Minnesota’s lakes. As I mentioned above, glaciers brought and pushed rocks into Minnesota, an example is sandstone, which is Sedimentary rock

  36. Jestin says:

    I claim that Glaciers used to move around Minnesota and my evidence is many things like an Esker an Esker is a river that was somehow in a glacier and when the glacier melted it left behind snake shaped ridges. A glacier moves the sedimentary rock across the ground scratching it and causing friction so then the glacier melts.

  37. Alex says:

    I claim that there are sedimentary rocks, igneous rocks and metamorphic rocks, they all start out as magma.my evidence is the rock cycle.

  38. Dante says:

    I claim that there are a lot of different rocks in Minnesota. My evidence is that when glaciers came they brought a lot of sediment, igneous, and metamorphic rocks down from Canada that have settled here in Minnesota. The striation and the scratching against rocks that shows that the glaciers were dragging against the ground pushing rocks and sediments forward.

  39. Kylie says:

    I claim that rocks found in Minnesota are sandstone, and other types of sedimentary rocks. My evidence is that glaciers moved sedimentary rocks and scraped the ground like seen with striation.

  40. Saze says:

    If I’d have to guess what type of rocks we have in Minnesota, I’d say mostly sedimentary because I see a lot of limestone and sandstone around places when I travel places.

  41. cody says:

    I claim that the differnet types of rocks like sandstone, limestone, shale, conglome. my evidence is the rocks change forms during the rock cycle.

    • cody says:

      Volcanic reaction in the north shore in lake serperior makes lava and ash.
      Sedimentary rocks are created in volcanoes.

  42. Kendra says:

    I claim that there are many types and Kinds of Rocks in Minnesota my Evidence is.. Rocks were brought by glaciers a long time ago Most were Sedimentary and metamorphic

  43. Saze says:

    I claim that Minnesota has all rocks. My evidence is that glaciers once covered Minnesota so once they moved on or melted, they left behind sedimentary rocks, although sedimentary rocks can convert to the other rocks, such as metamorphic rocks and igneous rocks.

  44. Carlos says:

    I claim that the rocks that are found in Minnesota are most likely sedimentary rocks and metamorphic. My evidence is that there are not any volcanic plates near Minnesota. Also, that in the article about glaciers we read about it talks about how rocks weren’t made here. And that it was glaciers that moved the 2 erratics that are in between Odessa and Appleton. Also, sediment is formed in water and Minnesota has over 10,000 lakes. There are also is marble which is a metamorphic rock that is mostly used for buildings in Minnesota.

  45. Makya says:

    There are 3 kinds of rocks in Minnesota igneous, sedimentary, and metamorphic. They came by volcanoes and glaciers. They came from volcanoes but were travelled here by the waves from the seas and lakes.

  46. Kaylene says:

    I claim that sedimentary rocks are found in Minnesota. my evidence is that rocks left along as the glacier moves makes different types of rocks. I would say the most common types of sedimentary rocks like sandstone, shale, limestone and more. You can also look at the rock cycle.

  47. ryan says:

    i claim the rocks found in Minnesota are sedimentary, metamorphic and ignacious rock. My evidence is that glaciers would pick up rocks and freeze them underneath, then melt again and go into Minnesota.

  48. Michael says:

    I claim my evidence is that sedimentary is the most common. Because you see a lil more than the other rocks like sandstone and limestone and etc. but what were all wondering is where did they come from?. I believe that when the glaicer’s came into minnesota they had rocks inside them. And when they melted they started to drop rocks and that’s where those rocks came from. But some other rocks i know in minnesota is shale is sedimentary and some of the rocks are

  49. Sarah says:

    My claim is that you can find all three types of rocks in Minnesota but the most common is sedimentary. Sedimentary is most common because we have so much soil and sand that it can form unlike an igneous rock because we don’t have any active or really recent volcanoes.
