Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces.

Front

What is erosion?

Back

Erosion is the process of moving sediments from one place to another, often by wind or water.

What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure.

Front

What is cementation in sedimentary rock formation?

Back

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