Passage A Avalanches are caused by a variety of conditions. When the temperature is cold and snow falls, the snow sticks to the ground. However, when the air temperature changes, the snow may slide away in pieces or slabs. Basically an avalanche happens when the gravity of snow heading downhill is greater than the gravity holds the snow together on the ground. Steep slopes on mountains, a recent heavy snowfall, a weak layer in the snow cover, changes in the weather, and changes in pressure on the surface (such as a skiers's sudden weight) can all contribute to the creation of an avalanche.

Which is the author's purpose for writing passage A?

a. To reveal how gravity contributes to an avalanche

b. To show the effects of stone slabs on an avalanche

c. to inform about the series of events that produce and avalanche

d. to describe methods for avoiding an avalanche My answer is C
