Landforms

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass. It occurs when the forces transporting the materials lose energy and can no longer carry them.

Front

What is a delta?

Back

A delta is a fan-shaped landform created by the deposition of sediment at the mouth of a river, where the river meets a body of water like an ocean or lake.

Front

What is erosion?

Back

Erosion is the process by which natural forces like water, wind, or ice remove and transport soil and rock from one location to another.

Front

What causes the formation of sand dunes?

Back

Sand dunes are formed when wind erodes sand from one location and deposits it in another, creating hills or ridges of sand.

Front

What is the role of river water in delta formation?

Back

River water slows down as it enters the ocean, causing sediments to settle and form a delta.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is an example of deposition?

Back

An example of deposition is when waves drop sand on the beach, adding to the beach's size.

Front

What is a canyon?

Back

A canyon is a deep, narrow valley with steep sides, often formed by the erosion of a river over a long period.

Front

What is a U-shaped valley?

Back

A U-shaped valley is a valley with a characteristic U shape, formed by glacial erosion.

Front

What is compaction?

Back

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