6th-ES-Unit 4.1-Erosion by Gravity-Open-Notes Flashcard

Front

What is the force that exists between any two objects that have mass?

Back

Gravity

Front

What is erosion by gravity?

Back

Erosion by gravity is the process where soil and rock are moved down slopes due to the force of gravity.

Front

What are the two main types of erosion caused by gravity?

Back

The two main types are landslides and rockfalls.

Front

What is a landslide?

Back

A landslide is the sudden and fast movement of a large amount of earth material down a slope.

Front

What is a rockfall?

Back

A rockfall is when rocks break loose from a steep slope and fall to the ground.

Front

What factors can trigger erosion by gravity?

Back

Factors include heavy rainfall, earthquakes, and human activities like construction.

Front

How does vegetation affect erosion by gravity?

Back

Vegetation helps to anchor soil in place, reducing the risk of erosion.

Front

What is the role of gravity in the erosion process?

Back

Gravity pulls materials down slopes, causing them to move and erode the landscape.

Front

What is mass wasting?

Back

Mass wasting is the movement of soil and rock down a slope due to gravity.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken materials.
