Exam 15: Mass Wasting

Identify the mass-wasting event in this image.

In which direction is mass wasting occurring in this image? (Note: The perspective is from the side.)

Rapid mass-wasting events do not always need a trigger.

Which of the following scenarios best describes the creation of the lahars associated with the eruption of Mt.St.Helens in 1980?

Assuming this location is near the Arctic Circle, what kind of mass wasting is visible in this image?

How is it possible for a landslide to occur without a trigger?

Which of the following will not oversteepen a slope and lead to mass wasting?

Southern California is famous for its wildfires, which are often exacerbated by the Santa Ana winds blowing through the canyons.What mass wasting event will later devastate the same fire-affected areas?

Tilted retaining walls are a sign of a landscape undergoing creep.

What geologic factors contributed to the severity of the Gros Ventre Landslide of 1925?

Which of the following factors does not influence mass wasting?

Which location is likely to experience creep?

Identify the mass-wasting event in this image.

Which of the following is not a way an earthquake can trigger mass wasting?

What is the crescent-shaped mark found at the top of a slump block?

How do both weathering and erosion work together to produce significant landforms such as broad valleys?

Compare and contrast rotational slides and translational slides.

Which one of the following locations would be most likely to have the mass wasting process visible here? (Note: The region is underlaid by permafrost.)

Stream valleys are produced through combined effects of mass wasting and running water.If running water alone were responsible for creating stream valleys, how would they appear?

The weathering process of frost action can make a slope less stable.
