Sedimentary Rocks

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the process where sediments are dropped or deposited in a new location.

Front

What is compaction?

Back

Compaction is the process where sediments are pressed together under pressure, reducing the space between them.

Front

What is cementation?

Back

Cementation is the process where minerals act like glue, binding sediments together to form solid rock.

Front

What role do minerals play in sedimentary rocks?

Back

Minerals act as a glue that helps to cement sediments together, forming sedimentary rocks.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to natural forces like wind, water, and temperature changes.

Front

What are the main processes that form sedimentary rocks?

Back

The main processes are weathering, erosion, deposition, compaction, and cementation.

Front

How does water contribute to sedimentary rock formation?

Back

Water can erode rocks, transport sediments, and help in the cementation process by carrying minerals.

Front

What is the difference between erosion and weathering?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces from one place to another.
