What geographical feature is characterized by being in the rain shadow of the Himalayas?

The Gobi Desert is located in the rain shadow of the Himalayas, which means it is positioned such that the mountain range blocks moist air coming from the ocean. As the moist air rises to cross the Himalayas, it cools and loses moisture in the form of precipitation on the windward side of the mountains. By the time the air descends on the leeward side, it is dry, creating arid conditions in regions like the Gobi Desert.

In contrast, the other geographical features mentioned do not share this specific association with the Himalayas. The Amazon Rainforest is located in South America and is characterized by heavy rainfall and biodiversity, while the Sahara Desert is in North Africa and is well-known for its dry, hot climate independent of the Himalayan influence. The Sonoran Desert is located in North America and has its own climatic factors that do not relate to the Himalayas. Thus, the unique geographical position of the Gobi Desert in relation to the Himalayas makes it the correct answer.
