Erosion and Deposition #2

Front

What is erosion?

Back

Erosion is the process by which soil, rock, and other surface materials are worn away and transported from one location to another by natural forces such as water, wind, ice, and gravity.

What is deposition?

Back

Deposition is the geological process in which sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

What is a sea stack?

Back

A sea stack is a coastal landform that is formed by the erosion of cliffs, leaving behind isolated columns of rock in the sea.

What is a beach?

Back

A beach is a landform along the shoreline of an ocean, sea, lake, or river, consisting of loose particles such as sand, gravel, or cobblestones, formed by the deposition of sediments by wave action.

Front

What role does gravity play in erosion?

Back

Gravity is a key agent of erosion that causes materials to move downhill, particularly in mountainous and steep areas, leading to processes like landslides and rockfalls.

What happens at the outside bend of a river?

Back

At the outside bend of a river, the water moves faster, which increases erosion and causes weathered rocks and sand to be picked up and carried downstream.

What is a U-shaped valley?

Back

A U-shaped valley is a valley formed by the erosion of glaciers, characterized by a wide, flat bottom and steep sides.

How do waves contribute to coastal landforms?

Back

Waves contribute to coastal landforms through the processes of erosion and deposition, shaping features like beaches, cliffs, and sea stacks.

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks and minerals at the Earth's surface, while erosion involves the movement of those materials from one location to another.
