95% of earth's crust is made out of this type of rock.
Igneous
400
This type of igneous rock is used to make countertops.
What is granite

How does a fossil form in sedimentary rock?
Animal dies in the lake, its undisturbed and sediments form over it
400
What are some qualities of metamorphic rock and one use
Extremely hard and strong, benches, flooring etc.
400
The force that drives the rock cycle
What is plate tectonics
500
What is the name of this igneous rock?
Obsidian
500
How do crystals form in igneous rocks?
By magma cooling. The faster it cools, the smaller the crystals. The longer it takes to cool, the larger the crystals. Crystals form from the amount of minerals in the rock.
