What is the rock cycle?
The series of processes on the surface, and inside the Earth, that slowly change rocks from one type to another.
What are the 3 types of rocks?
Igneous, Metamorphic, Sedimentary
What are igneous rocks?

5. Extrusive: hardened at the Earth’s surface.
Igneous Rock : A type of rock that forms from the cooling of molten rock at, or below the Earth’s surface.
There are two groups:
Extrusive: hardened at the Earth’s surface.
Intrusive: hardened below the Earth’s surface.
