Which region is described as having desert-like conditions due to orographic lift?

The Great Basin of Nevada is characterized by desert-like conditions primarily due to orographic lift, a phenomenon that occurs when moist air encounters mountains. When air rises over the Sierra Nevada mountain range, it cools and condenses, leading to precipitation on the windward side. As the air descends on the leeward side, it becomes warmer and drier, creating arid conditions typical of the Great Basin. This results in a rain shadow effect that limits moisture availability in the region, contributing to its desert-like climate.

In contrast, the other regions listed do not primarily experience desert-like conditions due to this mechanism. The Amazon Basin is known for its lush rainforests and high precipitation levels, while the Appalachian Mountains do not create significant rain shadows. The Himalayas, although they do create orographic lift, are associated with both very high rainfall on their windward slopes and substantial moisture retention, leading to diverse ecosystems rather than the arid conditions found in the Great Basin.
