Geologic Processes

What is a floodplain?

Back

A floodplain is a flat area of land adjacent to a river or stream that is prone to flooding. It is formed by the deposition of sediment during floods.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, such as an ocean or lake, and is characterized by the deposition of sediment.

Front

What is a sandbar?

Back

A sandbar is a submerged or exposed ridge of sand, gravel, or other sediment that is formed by the action of waves and currents.

Front

What is an escarpment?

Back

An escarpment is a steep slope or cliff that separates two relatively level areas of differing elevations.

Front

What is the definition of elevation?

Back

Elevation is the height of a point above sea level.

Front

What is topography?

Back

Topography refers to the arrangement of the natural and artificial physical features of an area, including its relief and landforms.

Front

What is relief in geography?

Back

Relief is the difference in elevation between the highest and lowest points in a particular area.

Front

What is the role of weathering in geologic processes?

Back

Weathering is the process that breaks down rocks into smaller particles, which can then be transported by erosion.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

How do weathering and erosion work together?

Back

Weathering breaks down rocks, and erosion transports the resulting sediments, changing the Earth's surface over time.
