Front

What is erosion?

Back

Erosion is the movement of sediments from one place to another, often caused by wind, water, or ice.

Front

What are index fossils?

Index fossils are species that existed on Earth for a short period, were abundant, and inhabited many locations, helping to date the layers of rock.

Front

What are examples of mass movement?

Back

Examples of mass movement include landslides, mudflows, slumps, and creeps.

Front

What is physical weathering?

Back

Physical weathering is the breakdown of rock into smaller pieces through physical changes, such as freeze-thaw cycles.

Front

What is chemical weathering?

Back

Chemical weathering is the process that breaks down rocks through chemical reactions, often involving water and minerals.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in a new location after being transported by erosion.

Front

What is abrasion?

Back

Abrasion is the wearing away of rock surfaces through friction and impact, often caused by wind or water carrying sediments.

Front

What is oxidation in geology?

Back

Oxidation is a chemical weathering process where minerals in rocks react with oxygen, often leading to rusting and weakening of the rock.

Front

What is a landslide?

Back

A landslide is a rapid movement of rock and soil down a slope, often triggered by heavy rain or earthquakes.
