Gravity Erosion

Front

What is gravity erosion?

Back

Gravity erosion is the process by which soil and rock are moved down a slope due to the force of gravity.

Front

What type of slopes do rapid mass movements usually occur on?

Back

Steep slopes.

Front

True or False: Trees can anchor soil to prevent it from moving.

Back

True.

Front

What type of mass movement might occur if you build your home on a steep hill during an earthquake?

Back

Landslide.

Front

What are mudflows?

Back

Mudflows are a type of mass movement where material behaves like a fluid, often occurring after heavy rainfall.

Front

What is creep in the context of gravity erosion?

Back

Creep is the extremely slow movement of soil and rock downslope.

Front

What is a landslide?

Back

A landslide is a rapid mass movement of rock and soil down a slope.

Front

What factors can trigger a landslide?

Back

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

Front

What is the difference between a rockfall and a landslide?

Back

A rockfall involves the sudden free-fall of rock from a steep slope, while a landslide involves the movement of a larger mass of soil and rock.

Front

What role do vegetation and trees play in preventing erosion?

Back

Vegetation and trees help anchor soil in place, reducing the risk of erosion and mass movements.
