Rocks and Rock Cycle

Front

What are foliated rocks?

Back

Foliated rocks are metamorphic rocks that have a layered or banded appearance due to the alignment of mineral grains under pressure.

Front

What are nonfoliated rocks?

Back

Nonfoliated rocks are metamorphic rocks that do not have a layered or banded appearance, typically composed of a single mineral.

Front

What results from the action of heat and pressure on rocks?

Back

The action of heat and pressure on rocks results in the formation of metamorphic rocks.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often formed through weathering and erosion.

Front

What are clastic rocks?

Back

Clastic rocks are sedimentary rocks formed from the accumulation of fragments of pre-existing rocks.

Front

What results from the action of weathering and erosion?

Back

The action of weathering and erosion results in the formation of sediment.

Front

What results from the cooling of magma and lava?

Back

The cooling of magma and lava results in the formation of igneous rocks.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including igneous, sedimentary, and metamorphic formations.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the solidification of molten rock material (magma or lava).

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that have been changed by heat, pressure, or chemically active fluids.
