4A - 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 is the process of weathering?

Back

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

Front

What is erosion?

Back

Erosion is the process of moving sediment from one place to another by natural forces such as wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediment settles out of the transporting medium (like water or wind) and accumulates in a new location.

Front

What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and helping to form sedimentary rock.

Front

What is cementation in sedimentary rock formation?

Back

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

Front

What are the main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of weathering, erosion, deposition, compaction, and cementation.

Front

What is an example of sedimentary rock?

Back

An example of sedimentary rock is sandstone, which is formed from sand particles.

Front

What role does water play in erosion?

Back

Water can carry away sediment and rocks, shaping landscapes through the process of erosion.
