Sedimentary Rock

Front

What is sedimentary rock?

Back

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

Front

What does compaction mean?

Back

The process by which layers are squeezed together by pressure forcing water out.

Front

What is cementation?

Back

The process by which particles of sediment begin to stick together.

Front

What does deposition mean?

Back

Deposition means the process by which sediments are laid down in a new location.

Front

What are the agents of change on the Earth?

Back

Ice, water, and wind are the main agents of change that shape the Earth's surface.

Front

What is the order by which sedimentary rock is created?

Back

Weathering, erosion, deposition, compaction, and cementation.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces such as water, wind, or ice.

Front

What is the role of water in sedimentary rock formation?

Back

Water helps in the transportation of sediments and plays a key role in the processes of compaction and cementation.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the minerals in the rocks.
