A metamorphic rock is formed at great depths when intense heat and pressure squeeze sedimentary rock.

A rock is a naturally occurring solid mixture of one or more minerals or organic matter.

Sedimentary rock is formed when grains of sediment are compacted and cemented together.

Magma is a hot liquid that forms when rock melts.

Intrusive igneous rock forms when magma pushes into surrounding rock below Earth's surface and cools into coarse-grained crystals.

The rock cycle is the process by which rock forms, changes from one type to another, is destroyed, and forms again.

Water, wind, ice, and heat break down rocks.

Sediment is small particles of rock, minerals, or organic material that can be transported by wind, water, or ice.

Intrusive igneous rocks form from magma that cools below the Earth's surface, while extrusive igneous rocks form from lava that erupts onto the Earth's surface.

Pressure causes the minerals in sedimentary rocks to realign and form new minerals, resulting in metamorphic rocks.
