Unit 4 - Changes to Earth's Surface

Front

What is a canyon?

Back

A canyon is a deep valley with steep sides, often formed by the erosion of rock by a river.

Front

What process leads to the formation of canyons?

Back

Canyons are most likely formed by rapidly moving water that erodes the rock over time.

Front

What is weathering?

Back

Weathering is the process in which rock is broken down into smaller pieces.

Front

What does erosion mean?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or settled in a new location after being transported.

Front

What is a delta?

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.

Front

What is a U-shaped valley?

Back

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

Front

What is the role of glaciers in shaping the Earth's surface?

Back

Glaciers shape the Earth's surface by eroding land and creating features like U-shaped valleys.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion involves the movement of those pieces from one place to another.

Front

What natural forces can change the Earth's surface?

Back

Wind, water, and ice are natural forces that can change the Earth's surface.
