Unit 3 The Rock Cycle

The Rock Cycle

The continuous change of rocks from one form to another.

Igneous Rock

rock that forms when magma or lava cool

a type of rock that forms from the cooling of molten rock (magma & lava) at or below Earth's surface

Metamorphic Rock

A type of rock that forms when Igneous or sedimentary rock get changed by great pressure and temperature.

Sedimentary Rock

A type of rock that forms when particles from other rocks or the remains of plants and animals are compacted and cemented together.

Magma

Hot, melted rock material BENEATH Earth's surface

Lava

Hot, melted rock material that reaches the Earth's SURFACE.

Intrusive

a type of igneous rock with large crystals and forms when magma cools slowly beneath Earth's surface.

Extrusive

a type of igneous rock formed on the surface of earth from lava. They have small or no crystals because they form quickly.

Compaction

A process that squeezes, or presses, sediments into sedimentary rocks

Cementation

"Gluing sediments together" (The sticking together of sediments)

Weathering

Chemical or physical process that breaks down rocks into smaller pieces.

Erosion

Processes by which rock, sand, and soil are broken down and MOVED to a different place.

Deposition

the placement or dropping of sediment after being carried away.

Sediments

small pieces of rocks that are broken up.
