Rock Cycle (Sedimentary, Igneous, and Metamorphic Rock)

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 the three main types of rocks?

Back

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

Front

What is an igneous rock?

Back

Igneous rocks are formed from the solidification of molten magma or lava.

Front

What is a sedimentary rock?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles.

Front

What is a metamorphic rock?

Back

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

Front

What is the texture of a non-foliated metamorphic rock?

Back

Non-foliated metamorphic rocks do not have a layered or banded appearance.

Front

What is the texture of a foliated metamorphic rock?

Back

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

Front

How are sedimentary rocks formed?

Back

Sedimentary rocks are formed through the processes of weathering, erosion, deposition, compaction, and cementation.

Front

What is an example of a sedimentary rock that may contain fossils?

Back

Limestone is a common sedimentary rock that may contain fossils.

Front

What processes lead to the formation of metamorphic rocks?

Back

Metamorphic rocks are formed through heat, pressure, and chemically active fluids acting on existing rocks.
