What is a hole in the Earth that melted rock flows out from and cools to form a mountain?

A crack in the Earth's crust

These are traces or remains of living things that died a long time ago.

Melted rock that flows out of the Earth's surface

A narrow valley with steep sides

Melted rock inside the Earth

Rocks formed from layers of sediment that get buried, pressed and cemented together

The breaking down of rocks into smaller pieces is called weathering.

The process in which one type of rock can change into a different type of rock is plate tectonics

A sudden shaking of Earth's crust

Rocks that have cooled and hardened from melted rock in the form of lava

The innermost layer of the Earth is called the crust

Huge pieces of Earth's crust and mantle that move are called....

The moving of broken rock from weathering.

Rocks that formed when heat and pressure change existing rocks into different rocks.

The middle layer of the Earth

The theory that explains the motion of plates on the Earth
