What is the key factor in slope stability?

• Steepness of the slope

• How many houses are built

• Earthquakes

Why is decreased vegetation a factor that can cause mass wasting?

• When plants are removed from the ground, the spaces they leave are filled with heavier rocks.

• Decreased vegetation is not a factor that causes mass wasting.

• Vegetation stabilizes soil at the surface, and their roots anchor soil under the surface.

• Decreased vegetation is not a factor that causes mass wasting.

A student notices that sand castles made with wet quartz sand are more stable than those made with dry quartz sand. He infers that the more water is added, the more stable the castle will be. Which is the most accurate evaluation of his inference?

• He is incorrect because too much water will dissolve the quartz.

• He is correct because water will absorbe and turn the quartz into clay.

• He is incorrect because the once the sand is saturated it will push apart the grains.

Where is mass wasting most likely to occur?

• Applacian mountains

• A corn field

• The beach

• Everglades swamp
