In which layer of the Earth are all 3 rock types formed?
The crust

Why is the rock cycle called a cycle?
Th rock cycle is a continuous loop of all types of rocks turning into all the other types of rocks.
What is the only rock type in which you will find fossils in? Why?

An igneous rock that cools and solidifies underneath the Earth's surface is called a(n) ________
Intrusive rock
What is the difference between weathering and erosion?
Weathering and erosion both break rocks down into smaller pieces called sediment, however, erosion transports that sediment to a new location.
Under what conditions will crystallization occur in igneous rocks?
If the magma cools very slowly, it will allow time for crystals to form.
What is metamorphism?
Heat and pressure being applied to rocks to create new ones.
