5.7A STAAR Review Sedimentary Rock and Fossil Fuel Formation

Front

What are fossil fuels?

Back

Fossil fuels are non-renewable forms of energy that we use to meet our needs, including coal, oil, and natural gas.

Front

Where is natural gas and oil formed?

Back

Natural gas and oil are formed at the bottom of oceans.

Front

What is the process of weathering?

Back

Weathering is the process that breaks down rocks into smaller particles.

Front

What is erosion?

Back

Erosion is the process that carries away loose sediments from one place to another.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of compaction and cementation of sediments over time.

Front

What is compaction in geology?

Back

Compaction is the process where sediments are pressed together under the weight of overlying materials.

Front

What role does water play in sedimentary rock formation?

Back

The weight of water compacts the sediment into rock over many years.

Front

What is sediment?

Back

Sediment is small particles of rock, minerals, and organic material that settle at the bottom of bodies of water.

Front

What is cementation?

Back

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

Front

What are the main types of sedimentary rocks?

Back

The main types of sedimentary rocks include clastic, chemical, and organic rocks.
