Sedimentary Rocks

Front

What is a sedimentary rock?

Back

A rock made of layers of compressed sediments.

Front

What are the four main processes that form sedimentary rocks?

Back

Erosion, deposition, compaction, cementation.

Front

What is erosion?

Back

The process by which running water, wind, or ice carry away bits of broken-up rock.

Front

What is deposition?

Back

The process where particles settle as loosely packed sediment.

Front

What is weathering?

Back

The breaking down of rocks into smaller pieces.

Front

What is compaction in sedimentary rock formation?

Back

The process where sediments are pressed together under pressure.

Front

What is cementation?

Back

The process where dissolved minerals crystallize and glue particles together.

Front

What is sediment?

Back

Small pieces of rock, minerals, or organic material that are transported by wind, water, or ice.

Front

How do sedimentary rocks differ from igneous rocks?

Back

Sedimentary rocks are formed from compressed sediments, while igneous rocks are formed from cooled magma or lava.

Front

What role does water play in the formation of sedimentary rocks?

Back

Water helps in erosion, transportation of sediments, and can aid in cementation.
