Rocks and Landforms
My rocks were Shale, Sandstone,Conglomerate, Brecca, Organi, Coal, and Limestone. These rocks all are found in the Uninted States. I used picked them because I couldn't chose witch other ones to pick. But these rocks are very unique in their own way. That's what I think anyway.
Shale rocks are so small that oil and nature gas products have a hard time moving through the rock.
Sandstone rocks are made of sand cemented into a rock.
Conglomerate are found in Rocky Mountains
Breccia can form during the emplacement of igneous bodies by explosives ex solution of volatile phase.
Coal is a black rock mostly made of carbon
Limestone is a chemical rock that has many uses in agriculture.
My next rocks are Slate, Shale, Gneiss, Marble, and Quartzite. These rocks are all Metamorphic rocks that form in different shapes and sizes.
Slate forms from mud, stone, or shales.
Shale has to contain clay or volcanic ash.
Gneiss has been subjected to higher temperature and pressures.
Marble usually originates as limestone or dolomite.
Quartzite froms in high temperature and high pressures.
My next set of rocks are Basalt, Granite, Obsidian, Pumice, and Phyolite. These are my Igneous rocks that I'm doing.
Basalt forms when bits of lava shoots out of a volcano.
Granite is a rock that has many uses in buildings
Obsidian forms when molten rocks cool very rapidly
Pumice os an extrusive rock with a vesicular texture and low gravity.
Rhythoite is a rock with high content, it was made from lava also.
