Which triangular desert covers the southern half of Israel?

The Negev Desert is the correct answer because it is the specific desert located in the southern half of Israel. This region covers approximately 60% of Israel's land area and is characterized by its arid climate, unique geological features, and varied topography, including mountains, valleys, and flat expanses. The Negev is significant not only for its size but also for its ecological diversity and cultural history, being home to various communities and archaeological sites.

The Taklamakan Desert, while a prominent desert, is located in Xinjiang, China, far from Israel. The Rub' al-Khali, also known as the Empty Quarter, is predominantly in Saudi Arabia and is one of the largest sand deserts in the world. The Gobi Desert, located in northern China and southern Mongolia, shares a different climate and geography compared to the Negev. Therefore, the Negev Desert is the only one among the choices directly associated with Israel's geography.
