Rocks and Rock Cycle

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the compaction and cementation of sediments, which can include fragments of other rocks, minerals, and organic materials.

Front

What is the parent rock of gneiss?

Back

Shale is the parent rock of gneiss, which is a type of metamorphic rock.

Front

What are clastic rocks?

Back

Clastic rocks are a type of sedimentary rock that are composed of fragments (clasts) of pre-existing rocks, minerals, and organic materials.

Front

What results from the cooling of magma and lava?

Back

The cooling of magma and lava results in igneous rock.

Front

What describes rocks with biological matter and fossils?

Back

Rocks with biological matter and fossils are classified as sedimentary rocks.

Front

What is the process of compaction and cementation?

Back

Compaction and cementation are processes that lead to the formation of sedimentary rocks by squeezing sediments together and binding them with minerals.

Front

What are the three main types of rocks?

Back

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

Front

How are igneous rocks formed?

Back

Igneous rocks are formed from the solidification of molten rock material, either magma (beneath the surface) or lava (on the surface).

Front

What is metamorphic rock?

Back

Metamorphic rock is a type of rock that has been changed from its original form due to heat, pressure, or chemically active fluids.

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, metamorphism, and melting.
