5.7A - Sedimentary Rock

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation and compaction of mineral and organic particles, often found in layers.

Front

What processes lead to the formation of sedimentary rock?

Back

The processes include weathering, erosion, deposition, compaction, and cementation.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to environmental factors like wind, water, and ice.

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by erosion.

Front

What is compaction?

Back

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

Front

What is cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together, forming solid rock.

Front

What are sediments?

Back

Sediments are small pieces of rock, minerals, or organic material that have been broken down by weathering.

Front

What role does water play in sedimentary rock formation?

Back

Water helps in weathering rocks, transporting sediments, and facilitating the processes of compaction and cementation.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion involves the movement of those pieces to new locations.
