Which is NOT a type of mass movement discussed?

• Rock slide

• Debris flow

• Lava flow

• Soil creep

Which mass movement is described as the gradual downhill movement of soil?

• Mudslide

• Debris flow

• Soil creep

• Rock slide

What causes debris flow?

• Ice melting

• Water evaporation

• Rapid collection of debris falling downhill

What distinguishes a mudslide from other types of mass movements?

• It involves large rocks.

• It's the slowest type.

• It's triggered by heavy rain.

• It only occurs in dry conditions.

What is a common preventive measure for rock slides?

• Covering slopes with nets

• Controlled rock removal

• Planting trees

• Building walls

How can you often tell soil creep has occurred?

• By measuring soil moisture

• By noticing misaligned structures

• Through the sound it makes

• By observing rapid soil movement

What type of sediment is typically deposited by gravity-induced erosion?

• Smooth and sorted

• Small and compact

• Round and large

• Angular and unsorted

What characteristic do sediments deposited by gravity share?

• They are smooth and rounded.

• They are well-sorted by size.

• They are predominantly large boulders.

• They are angular and mixed in size.
