TEST Review (Fossils, Weathering, Erosion, Deposition)

Front

What is a cast in terms of fossils?

Back

A cast is a replica of an organism created when minerals fill in an imprint of the organism.

Front

What are the steps in the fossilization process?

Back

1) Plant or animal dies. 2) Plant or animal is buried. 3) Plant or animal is left alone for years. 4) Minerals seep into the object and create a rock.

Front

What is the main cause of U-shaped valleys?

Back

U-shaped valleys are mainly caused by glaciers through the processes of weathering, erosion, and deposition.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to environmental factors.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by natural forces such as wind or water.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of a once-living organism.

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation and compaction of mineral and organic particles.
