How do we form igneous rock, sedimentary rock, and metamorphic rock? Where does each kind of rock form within the Earth?
What is igneous rock forms when molten rock cools and becomes solid. It can form in the Earth's crust and inside the Earth.
Sedimentary rock can form pieces of older rocks, plants, and loose material get pressed or cemented together. They form in the Earth's crust and mantle.
Metamorphic rocks form when heat or pressure causes older rocks to change into new types of rocks. This happens in the Earth's mantle and crust.
