Question 1

What are some ways by which a slope can become oversteepened? How can oversteeping cause mass wasting?

Accepted Answer

Slopes are oversteepened by undercutting by streams or waves,or excavations by human activities at their base.When the slope's base is removed,the slope angle increases,and the gravitational force acting parallel to the slope increases as well.

Question 2

What is a slope-stability map?

Accepted Answer

A slope-stability map portrays the mass wasting hazards of an area.

Question 3

What factors contribute to mass wasting in tropical versus arid and semiarid climates?

Accepted Answer

In the tropics,high temperatures and rainfall extend weathering to depths of tens of meters,and mass movements are common in the deep weathering zone.In arid and semiarid regions,the weathering zone is much shallower,but a short period of intense rain falling on a slope with little vegetation to absorb the water can cause rapid runoff and mass wasting.
