How are metamorphic rocks formed?
By great heat and pressure beneath the earth's surface
100
How are igneous rocks formed?
By the cooling and crystallization of magma or lava

What is one way sedimentary rocks are formed?
Layers of sediment pile up at the bottom of oceans, lakes, and rivers, and become tightly packed together under pressure.
