Rocks and Rock Cycle

Front

What are clastic rocks?

Back

Clastic rocks are a type of sedimentary rock formed from the accumulation and compaction of mineral and rock fragments.

What are foliated and nonfoliated rocks?

Back

Foliated rocks are metamorphic rocks that have a layered or banded appearance due to the alignment of minerals. Nonfoliated rocks do not have this layered appearance.

Front

What characterizes sedimentary rocks with biological matter?

Back

Sedimentary rocks with biological matter often contain fossils and are formed from the accumulation of organic materials.

What is the process of compaction and cementation?

Back

Compaction and cementation are processes that transform loose sediment into solid sedimentary rock by applying pressure and binding particles together.

Front

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

Back

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

Front

Define igneous rocks.

Back

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

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 erosion, sedimentation, and metamorphism.

Front

What are the two main types of igneous rocks?

Back

The two main types of igneous rocks are intrusive (plutonic) rocks, which form below the Earth's surface, and extrusive (volcanic) rocks, which form on the surface.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, which can accumulate and form sedimentary rocks.

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of weathering, erosion, deposition, compaction, and cementation of sediments.
