Question

________ move downslope as much as 160 kilometers per hour.

A) Solifluction lobes
B) Landslides
C) Slump blocks
D) Rock glaciers
E) Debris flows

Answer 1

Landslides can move as quickly as 160 kilometers per hour and are caused by various factors including gravity, erosion, heavy rains, earthquakes, and volcanic eruptions.

Step-by-step explanation:

Landslides can move downslope as quickly as 160 kilometers per hour, due to a variety of factors including gravity acting on over-steepened slopes, erosion by rivers, glaciers, or ocean waves, and events such as heavy rains, earthquakes, and volcanic eruptions. These events can cause excessive saturation weakening slopes, loading them with weight, and triggering their failure. Landslides can involve a range of ground movements, such as rock falls, deep slope failures, and shallow debris flows, which can cause substantial damage and even fatalities.
