What is a natural, nonliving substance that makes up rocks?
Mineral
A type of rock that forms from melted rock that cools and hardens.
What is igneous rock?
This process involves wind, water, and ice moving rocks.

Minerals
During the rock cycle, how can a rock become an igneous rock?
Any rock can melt and cool to form an igneous rock.
What are the two differences between oceanic and continental crust?
oceanic is small but more dense
What is the hardest mineral?
