Sedimentary Rock and Fossil Fuels Review

Front

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 layered over time.

Front

How is sedimentary rock formed?

Back

Sedimentary rock is formed when sediments are compacted and cemented together, often under the weight of layers above.

Front

What are fossils?

Back

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

Front

What is coal?

Back

Coal is a type of fossil fuel that forms from the remains of decaying plants, typically found in sedimentary rock.

Front

What is oil?

Back

Oil is a fossil fuel that forms from the remains of tiny marine organisms, usually found in ancient ocean sediments.

Front

What conditions are needed for fossil fuels to form?

Back

Fossil fuels form under conditions where dead organisms are buried under layers of sediment for millions of years.

Front

What is the role of sediment in forming sedimentary rock?

Back

Sediment consists of small particles that accumulate over time and, when compacted, can form sedimentary rock.

Front

Where are sedimentary rocks commonly found?

Back

Sedimentary rocks are often found in areas like river mouths, lakes, and ocean floors.

Front

What is compaction in geology?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume and forming rock.

Front

What is cementation?

Back

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