Unit 2 Lesson 2 Wind, Ice and Gravity

Front

What is mass movement?

Back

Mass movement refers to the movement of soil and rock down a slope due to the force of gravity.

Front

What is a mudslide?

Back

A mudslide is a type of mass movement where water-saturated soil and debris flow down a slope.

Front

What are dunes?

Back

Dunes are hills of sand formed by the wind when it slows down and deposits sand.

Front

What is the role of gravity in erosion?

Back

Gravity is the primary force that causes erosion and deposition in processes like landslides and mudslides.

Front

What is sediment?

Back

Sediment is small particles of rock and soil that can be transported by wind, water, or ice.

Front

What happens to sediment when wind slows down?

Back

When wind slows down, it deposits the sediment it was carrying, starting with the heaviest particles.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

Front

What is deposition?

Back

Deposition is the process by which sediments are laid down in a new location after being transported.

Front

What are the agents of erosion?

Back

The main agents of erosion are water, wind, ice, and gravity.

Front

What is a landslide?

Back

A landslide is a sudden and fast movement of rock and soil down a slope, often triggered by gravity.
