What is a U-shaped valley and how is it formed?

Back

A U-shaped valley is a valley with a characteristic U-shape, formed by the erosion of a glacier. The glacier carves out the valley as it moves, creating steep sides and a flat bottom.

What is the process of deposition in relation to landforms?

Back

Deposition is the geological process where material is added to a landform. It occurs when the energy of the transporting medium (like water or wind) decreases, causing sediments to settle and accumulate, forming features like deltas.

What role does water play in the formation of canyons?

Back

Water, through the processes of weathering and erosion, carves out canyons over time. Rivers cut through rock layers, deepening and widening the valley to create a canyon.

What are the main processes involved in the formation of a canyon?

Back

The main processes are weathering, which breaks down rocks, and erosion, which removes the weathered material. Together, they shape the landscape into a canyon.

How do sand dunes form and what agent of change is responsible?

Back

Sand dunes form through the action of wind, which transports sand particles and deposits them when the wind speed decreases. This accumulation of sand creates the characteristic shape of dunes.

Front

What is the difference between weathering and erosion?

Back

Weathering is the process of breaking down rocks into smaller pieces without moving them, while erosion involves the movement of those weathered materials from one location to another.

What is the significance of glaciers in shaping landforms?

Back

Glaciers are significant agents of change that shape landforms through processes like erosion and deposition, creating features such as U-shaped valleys, fjords, and moraines.

What is a delta and how does it form?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment carried by the river as its flow velocity decreases.

What are the characteristics of a canyon?

Back

Canyons are characterized by steep sides, a deep valley, and often a river running through them. They are formed primarily by the erosive power of water.

What types of landforms can be created by wind erosion?

Back

Wind erosion can create various landforms, including sand dunes, loess deposits, and eroded rock formations known as yardangs.
