Question

Distinguish between fast and slow mass movement processes

A) Slow: Earthquakes, Fast: Mudflows
B) Slow: Landslides, Fast: Rockfalls
C) Slow: Avalanches, Fast: Glacier movement
D) Slow: Tidal forces, Fast: Hurricanes

Answer 1

Slow mass movement processes include landslides and avalanches, while fast mass movement processes involve mudflows and rockfalls.

Step-by-step explanation:

In geology, mass movement refers to the downslope movement of rock or soil under the influence of gravity. There are different types of mass movement processes categorized based on their speed. Slow mass movement processes include landslides, avalanches, and slow glacier movement. Fast mass movement processes involve mudflows, rockfalls, and hurricanes. For example, a landslide is a slow mass movement process where a large mass of rock and soil gradually moves down a slope, while a mudflow is a fast mass movement process where a large amount of water-saturated debris quickly flows downhill.
