Mass Movement Quiz

What is mass movement?

• The movement of air in a circular motion

• The movement of rocks horizontally

• The movement of water uphill

• The movement of loose, weathered material downslope under the influence of gravity

Which factor affects mass movement by making the scree heavier and acting as a lubricant?

• Gradient

• Water content

• Human activity

• Vegetation

What does the gradient of a slope determine in relation to mass movement?

• The color of the soil

• The speed of soil and rock movement

• The type of vegetation present

• The temperature of the area

How do the roots of plants help prevent mass movement?

• By binding soil particles together

• By increasing the water content

• By making the soil lighter

• By causing landslides

What type of mass movement is characterized by slow movement of soil downslope?

• Mudflow

• Soil creep

• Bogburst

• Landslide

What causes a bogburst to occur?

• Earthquakes

• Heavy rainfall saturating peat

• Volcanic activity

• Deforestation

Which fast mass movement type occurs when soil is saturated with water following heavy rainfall?

• Soil creep

• Mudflow

• Landslide

• Bogburst

What can combat climate change to help reduce mass movements?

• Increased rainfall

• Deforestation

• Human activity

• Combating climate change

What is one example of human activity that can cause landslides?

• Planting more trees

• Building roads on slopes

• Protecting the environment

• Reducing water content

What type of mudflow occurs following volcanic activity when snow on a mountain melts and mixes with soil and volcanic ash?

• Soil creep

• Landslide

• Lahar

• Bogburst
