Exam 10: Mass Wasting

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

What role does weathering play in mass wasting?

All other factors being equal, the chance of mass wasting is increased by:

Most large mass movements can be prevented given sufficient study and planning.

Creep usually involves only small areas, such as the steepest portions of a hillside.

What climatic conditions are most conducive to solifluction?

Slumps occur most commonly in well-consolidated material.

The downward movement of material along a curved surface of rupture, which is characterized by the backward rotation of the displaced block, is called a(n) ____________________.

What methods can be used to stabilize a hillside?

The slow downslope movement of water-saturated surface sediment is:

Among the types of slides are:

Mass movements in which rocks freefall through the air are known as ____________________.

A rainstorm can trigger the landslide of an unstable slope.

What is a slope-stability map?

All slopes are constantly adjusting to new conditions referring that they are in a state of ____________________.

Mass wasting is most likely to occur in:

How would reducing the angle of slope in a hillside help to stabilize it? What two methods can be used to reduce a slope's angle?

Landslides can be caused by:

Completion Geologists call the downslope movement of material under the direct influence of gravity ____________________.

Compare and contrast rapid mass movements and slow mass movements.
