What is this?
How did it form?
Science Log Questions: What kind of rock is formed with immense heat and pressure? What rock is formed when sedimentary shale is put under these conditions? (Hint: Be careful how you pronounce it!)
Science Log Question: Is granite an intrusive or extrusive rock? How do you know?
Granite
Schist
Science Log Question: What type of sedimentary rock is formed from previous living material?
Limestone
Granite
Schist
During the next several million years, other sedimentary rocks were deposited on the existing landscape of (what we now call) the Black Hills. The next type of sedimentary rock to be deposited was a red shale.
Red Shale
Limestone
Granite
Schist
The next sedimentary rock to be deposited in the area was a slightly harder rock composed mainly of sandsize mineral or rock grains. This rock is called sandstone.
