Sedimentary Rock

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed from the accumulation and compaction of mineral and organic particles over time.

Front

What process occurs when new sediment layers are deposited on top of older layers?

Back

Compaction.

Front

How long does it typically take for sedimentary rock to form?

Back

Millions of years.

Front

What is the last process that happens when sediment is dropped off in a pile?

Back

Deposition.

Front

What is deposition in the context of sedimentary rocks?

Back

Deposition is the process where sediment is laid down in new locations, such as rivers, lakes, and oceans.

Front

What happens to sediment during compaction?

Back

Sediment is pressed together under the weight of overlying materials, reducing its volume.

Front

What is cementation in sedimentary rock formation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together.

Front

Is a rock formed at the deposition step?

Back

No, a rock is not formed at the deposition step.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What role does weathering play in the formation of sedimentary rocks?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited.
