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 found in layers.

Front

What processes lead to the formation of sedimentary rock?

Back

The formation of sedimentary rock involves 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, rain, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which sediment and soil are removed from one location and transported to another by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations, often forming layers.

Front

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where layers of sediment are pressed together under the weight of overlying materials, reducing their volume.

Front

What is cementation?

Back

Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediment particles, binding them together.

Front

How long does it take for sedimentary rock to form?

Back

It can take millions of years for sedimentary rock to form through the processes of compaction and cementation.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient organisms, often found in sedimentary rock.

Front

How do fossils form in sedimentary rock?

Back

Fossils form when organisms are buried by sediment, which then compacts and cements around them, preserving their shape.
