Sedimentary rocks

Front

What are sedimentary rocks?

Back

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

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process where particles are squeezed together under pressure.

Front

What is cementation?

Back

Cementation is the process in which dissolved minerals crystallize and glue sediment together.

Front

What is deposition?

Back

Deposition is the process where sediment settles out of the water or wind that is carrying it.

Front

What is erosion?

Back

Erosion is the process of wearing away rocks and soil by wind, water, or ice.

Front

What is sediment?

Back

Sediment refers to small pieces of rock, sand, and other materials that are transported and deposited by natural forces.

Front

What characteristic do sedimentary rocks often have?

Back

Sedimentary rocks often have striped layers.

Front

What is the formation process of most sedimentary rocks?

Back

The formation process of most sedimentary rocks follows erosion, deposition, compaction, and cementation.

Front

What are examples of sediment?

Back

Examples of sediment include small pebbles, sand, and clay.

Front

What role do minerals play in sedimentary rocks?

Back

Minerals can crystallize and help glue sediment together during the cementation process.
