5.7B - Changes to Earth's Surface (Landforms)

Front

What is a U-shaped valley?

Back

A U-shaped valley is a landform created by the erosion of glaciers, characterized by its wide, rounded bottom and steep sides.

Front

What are the main agents of change that shape Earth's surface?

Back

The main agents of change are wind, water, ice (glaciers), and human activity.

Front

How do glaciers change the landscape?

Back

Glaciers change the landscape by eroding land, creating valleys, and depositing sediment as they move.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or settled after being transported by wind, water, or ice.

Front

What landform is created by the action of rivers?

Back

Rivers can create various landforms, including river valleys, deltas, and canyons.

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, characterized by sediment deposition.

Front

What role does water play in shaping landforms?

Back

Water shapes landforms through erosion, transportation of sediments, and deposition, creating features like valleys and deltas.

Front

What is a V-shaped valley?

Back

A V-shaped valley is formed by the erosive action of a river, characterized by its narrow, steep-sided shape.
