Sedimentary Rocks

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks that are formed by the accumulation and compaction of sediments.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of compaction and cementation of sediments.

Front

What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume.

Front

What is cementation in sedimentary rock formation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediments together.

Front

What are the three main types of sedimentary rocks?

Back

The three main types of sedimentary rocks are clastic, chemical, and organic.

Front

What is a clastic sedimentary rock?

Back

Clastic sedimentary rocks are formed from fragments of other rocks and minerals that have been compacted and cemented together.

Front

What is an example of a clastic sedimentary rock?

Back

An example of a clastic sedimentary rock is conglomerate.

Front

What is a chemical sedimentary rock?

Back

Chemical sedimentary rocks form when minerals precipitate from solution, often due to evaporation.

Front

What is an example of a chemical sedimentary rock?

Back

An example of a chemical sedimentary rock is chert.

Front

What is an organic sedimentary rock?

Back

Organic sedimentary rocks are formed from the remains of living organisms, such as plants and animals.
