Rocks & Rock Cycle

Front

What is weathering and erosion?

Back

Weathering is the process of breaking down rocks into smaller pieces, while erosion is the movement of those pieces from one place to another.

Front

What type of rock is formed from cooled lava?

Back

Igneous Rock.

Front

What is a metamorphic rock?

Back

A metamorphic rock is formed from existing rocks that have been changed by heat, pressure, or chemical processes.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from fragments of other rocks, minerals, and organic materials that have been compacted and cemented together.

Front

What type of rock might contain fossils?

Back

Sedimentary Rock.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including the processes of igneous, sedimentary, and metamorphic rock formation.

Front

What is crystallization in the context of rocks?

Back

Crystallization is the process where minerals form and grow from cooling magma or evaporating solutions.

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 compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and forming solid rock.

Front

What is cementation in sedimentary rock formation?

Back

Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediment grains, binding them together.
