5.7A STAAR Review Sedimentary Rock and Fossil Fuel Formation

Front

What is cementation?

Back

The process by which dissolved minerals in water glue particles of sediment together into one rock.

Front

What is compaction in the sedimentary rock process?

Back

Compaction is the process of squeezing sediments together under pressure.

Front

What does deposition mean in geology?

Back

Deposition is the dropping off of sediments in new locations.

Front

What is a sedimentary rock?

Back

A type of rock that forms in layers when sediments from weathered rocks are eroded and deposited, then compacted and cemented.

Front

What is the role of erosion in sedimentary rock formation?

Back

Erosion is the process that removes sediments from one location and transports them to another.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient living organisms found in sedimentary rocks.

Front

How do fossils form?

Back

Fossils form when organisms are buried by sediment, which then compacts and cements over time.

Front

What is the significance of sedimentary rocks?

Back

Sedimentary rocks provide important information about Earth's history and past environments.

Front

What is the process of lithification?

Back

Lithification is the process of turning sediments into solid rock through compaction and cementation.
