Detailed explanation-1: -Answer and Explanation: Death Valley formed from orographic lifting. Orographic lifting is the process in which a parcel of air moves up the slopes of a mountain leading to its cooling. This results in rainfall on the windward side of the mountain however it results in dryness on the leeward side.

Detailed explanation-2: -Extremes of climate and geography make it the ultimate showcase of an American desert. Death Valley National Park includes all of Death Valley, a 156-mile-long north/south-trending trough that formed between two major block-faulted mountain ranges: the Amargosa Range on the east and the Panamint Range on the west.

Detailed explanation-3: -Physiography. The Sierra Nevada is an asymmetrical range with its crest and high peaks decidedly toward the east. The peaks range from 11, 000 to 14, 000 feet (3, 350 to 4, 270 metres) above sea level, with Mount Whitney, at 14, 494 feet (4, 418 metres), the highest peak in the coterminous United States.

Detailed explanation-4: -When wind hits a mountain and is forced to rise over the mountain, this is called orographic lift. This simple concept is such a powerful lifting force in the atmosphere that it is likely responsible for the majority of the snow that falls in big mountains.
