AVALANCHE!!

I read in National Geographic about avalanches. It said that avalanches can be caused on a slope of at least a 25% or more. Avalanches can destroy buildings with slabs of ice or powder snow. Avalanches are the same as 20,000 elephants running down hill.

Dr. Adams studies avalanches by getting buried in one. He is inventing a program that will tell us when an avalanche will occur so it will save many lives. He sits in a shed on the side of a mountain to wait for a bomb to go off to make an avalanche.
