Question 1

Ground that remains permanently frozen is called ____________________.

Accepted Answer

permafrost

Question 2

How does a mudflow differ from a debris flow?

Accepted Answer

A mudflow is up to 30% water, and at least 50% clay-sized particles. A debris flow contains less water and larger particles.

Question 3

What are quick clays, and how do they cause damage?

Accepted Answer

Quick clays are clays that spontaneously liquefy and flow. These fine sediments were originally deposited in a marine environment where their pore spaces were filled with seawater. The ions helped establish strong bonds between clay particles strengthening them. When the clays were uplifted above sea level and groundwater replaced saltwater, the effectiveness of the ionic bonds between the particles was reduced and the strength of the clay was weakened.

Question 4

How can vegetation affect the likelihood of mass wasting?

Accepted Answer

Vegetation can absorb water, a

Question 5

Why is there sometimes a wire mesh covering the sides of a steep slope? What are the characteristics of the type of mass wasting this is meant to prevent?

Accepted Answer

Wire mesh is put on slopes to prevent di
