Answer 1

This is actually an Earth Science question, so in the future, please post any questions you have concerning this topic in that section (: However, I'll help you answer this one. First of all, we know landslides are masses of rock, earth or debris moving down a slope, and that it's mostly caused by heavy rain. Why do you think heavy rain causes the landslides? As a comparison, think of the Dust Bowl that occurred in the U.S. in the 1930s. They first began after farmers had heavily plowed the Great Plains, ripping up the native grass that usually held soil and moisture in place even during terrible storms. Droughts and a lack of grass led to severe dust storms during the 1930s.

So, based on this background info, what do you think is the answer?
