Areas immediately to the leeward of mountains have a microclimate with sparse precipitation called a C. rain shadow. As moist air moves landward, it will hit the mountain, which will force the air to move up. As moist air moves higher, it becomes cooler and thus releases its moisture thereby causing rainfall. Once what's left of the clouds passes over the top of the mountain, its moisture has been lost and a rain shadow is formed.
The appropriate answer is a. The Tetons. Continental to continental plate collision occurs when continental crust comes together and compression and folding and faulting over time leads to the formation of extensive fold mountain ranges. The Appalachians, The Alps and the Himalayas were all formed at continental collision plate margins. <span />
