5.7A STAAR Review Sedimentary Rock and Fossil Fuel Formation

Front

What are sediments?

Back

Small pieces of rock, soil, and other materials that are deposited by water, wind, or ice.

Front

Where was coal formed?

Back

Coal was formed in swamps.

Front

Why do most sedimentary rocks form in the ocean?

Back

Because oceans are where most bits of broken rock get deposited.

Front

What is the process of compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are buried and squeezed together to form sedimentary rock.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form when broken bits of other rock are deposited, buried, squeezed, and cemented together.

Front

What is deposition?

Back

The process by which sediments are laid down in new locations.

Front

What is erosion?

Back

The process by which rock and soil are worn away and transported by natural forces such as wind or water.

Front

What is the role of water in sedimentary rock formation?

Back

Water helps transport sediments and can also aid in the cementation process.

Front

What are fossils?

Back

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

Front

What is cementation?

Back

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