Rocks and the Rock Cycle

Front

What are the three main groups of rocks?

Back

Igneous, Sedimentary, Metamorphic

Front

How are rocks classified?

Back

Rocks are classified by how they are formed.

Front

What process forms sedimentary rocks?

Back

Weathering, Erosion, Deposition, Compaction, Cementation.

Front

What type of rock is formed by cooling and crystallization?

Back

Igneous rocks.

Front

What is regional metamorphism?

Back

The process that occurs along plate boundaries; rock gets buried and heat and pressure build up.

Front

What is the primary characteristic of igneous rocks?

Back

They are formed from the cooling and solidification of magma or lava.

Front

What is sedimentary rock primarily formed from?

Back

The accumulation and compaction of sediment.

Front

What is the rock cycle?

Back

The continuous process of rock formation and transformation between igneous, sedimentary, and metamorphic rocks.

Front

What is metamorphism?

Back

The process by which rocks change due to heat, pressure, or chemically active fluids.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive rocks form from magma that cools slowly beneath the Earth's surface, while extrusive rocks form from lava that cools quickly on the surface.
