The Rock Cycle
Thank you!

Metamorphic Rock
Augite
This mineral doesn't really have any uses. It is only really used by scientists in the labs.
The Rock Cycle explains how metamorphic, igneous, and sedimentary rock are related and how the different rocks change over time.
This mineral can be used for jewelry and small windows!!! Diamonds are also rated # 10 on the Mohs Hardness Scale.
Sedimentary Rock
This rock type forms when pieces of other rock or sediments are pressed together and cemented as one mass. They also can be made out of once living things (organic) such as plants and animals. A fossil can't form in an igneous rock because the temperature is too high to restore the fossil, and a metamorphic rock would then be heated. If a fossil were to be lying on the ground, it would soon be buried by sediments and then eventually would be a sedimentary rock.
Sedimentary Rocks
Sandstone
Coal
Igneous Rock
This rock type forms when magma or lava has cooled above or below Earth's surface. The cooling of magma under ground is known as an intrusive rock. The cooling of lava on the surface is known as an extrusive rock.
Granite
Basalt
Obsidian
Igneous Rocks
This rock type forms when a rock is under heat and pressure. A scientist can categorize metamorphic rock as foliated or non-foliated. Foliated rock has grains that are arranged in parallel layers. Non-foliated rock's grains are not assorted in any orderly fashion.
