Sedimentary, Metamorphic, and Igneous Rock

Front

What is erosion?

Back

Erosion is the process by which wind, water, ice, and gravity carry sediments away from their original location.

Front

What type of rock is formed by the cooling and solidification of lava?

Back

Extrusive Igneous Rock.

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock that is made of layers of compressed sediments.

Front

What type of rock is formed from magma?

Back

Intrusive Igneous Rock.

Front

What are chemical rocks?

Back

Chemical rocks are formed when water evaporates and minerals crystallize.

Front

What is the process of deposition?

Back

Deposition is the process by which sediments are laid down in new locations after being transported by erosion.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

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

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How are metamorphic rocks formed?

Back

Metamorphic rocks are formed from existing rocks that are changed by heat, pressure, or chemically active fluids.
