Sedimentary Rocks

Front

What is erosion?

Back

Erosion is the process by which water, wind, ice, or gravity removes pieces of rock and soil from one location and transports them to another.

Front

What are the forces involved in producing sediments?

Back

The forces involved in producing sediments are weathering and erosion.

Front

What is NOT needed to make sedimentary rocks?

Back

Organic matter is not needed to make sedimentary rocks.

Front

What is the correct order of sedimentary rock formation?

Back

The correct order is weathering, erosion, deposition, compaction, cementation.

Front

What causes valleys formed by glaciers?

Back

Valleys formed by glaciers are a result of glacial erosion.

Front

Define sediment.

Back

Sediment is small pieces of rock, minerals, or organic material that have been broken down by weathering and erosion.

Front

What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume.

Front

What is cementation in sedimentary rock formation?

Back

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

Front

What role does water play in sedimentary rock formation?

Back

Water helps transport sediments and can also aid in the processes of compaction and cementation.

Front

What is deposition?

Back

Deposition is the process where sediments settle out of the transporting medium (like water or wind) and accumulate in layers.
