Erosion & Deposition

Front

What is erosion?

Back

Erosion is the process by which soil and sediment (weathered rock) are transported (moved) from one place to another by water, wind, glaciers, and gravity.

Front

What is deposition?

Back

Deposition is the process by which sediment is laid down or settled in a new location, often forming features like river deltas.

Front

What is a river delta?

Back

A river delta is a landform that forms at the mouth of a river, where it meets a body of water, and sediment is deposited.

Front

What are meanders?

Back

Meanders are broad, C-shaped curves that develop in mature streams as they flow over time.

Front

What is a landslide?

Back

A landslide is a mass wasting event where soil and rock move rapidly down a slope, often posing risks to homes and infrastructure.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller particles through physical, chemical, or biological means.

Front

What role does gravity play in erosion?

Back

Gravity pulls materials down slopes, contributing to erosion by causing soil and rock to move downhill.

Front

What are longshore currents?

Back

Longshore currents are ocean currents that move parallel to the shore, affecting sediment transport along coastlines.

Front

What is a floodplain?

Back

A floodplain is an area of land adjacent to a river that is prone to flooding and is often rich in nutrients due to sediment deposition.

Front

What is creep in geology?

Back

Creep is a slow, gradual movement of soil and rock down a slope, often imperceptible but can lead to significant changes over time.
