Mass Movement Worksheet

Mass movements are more likely when which of the following occurs?

• The slope becomes steeper

• The ground is completely flat

• There is no water present

• Vegetation is dense and stable

Four types of mass movement are listed in the passage. Which of the following is NOT a type of mass movement?

• Rockfalls

• Landslides

• Mudflows

• Earthquakes

• Rotational slips

The types of mass movement are:

• Creep, slump, landslide, and flow

• Evaporation, condensation, precipitation, and collection

• Erosion, deposition, transportation, and weathering

• Melting, freezing, sublimation, and deposition

Fragments of rock break off and fall to the ground as scree (angular rocks). This is usually caused by freeze thaw weathering. What is this type of mass movement called?

• Landslide

• Rockfall

• Erosion

• Deposition

Blocks of rock slide downhill. Material shifts in a straight line. Usually when the bedding plane of the rock is no longer parallel to the earth’s surface. What is this type of mass movement called?

• Rockfall

• Landslide

• Avalanche

• Creep

The types of mass movement include:

• Creep, slump, landslide, and flow

• Erosion, deposition, weathering, and transportation

• Condensation, precipitation, evaporation, and infiltration

• Melting, freezing, sublimation, and deposition

Rotational slip occurs when saturated soil and weak rock slump along a ______ surface.

• curved

• flat

• angular

• vertical

Mudflow usually occurs when the soil is on a slope of 10° and has an underlying layer of ______ rock which has not allowed water to pass through.

• impermeable

• permeable

• porous

• sedimentary
