Arabian Desert

The Rub' al Khali, also known as the Empty Quarter, is the largest contiguous sand desert in the world, located within the interior of the Arabian Peninsula. It spans parts of Saudi Arabia, Yemen, Oman, and the United Arab Emirates, covering an area of roughly 650,000 square kilometers.

The Arabian Desert covers nearly the entire Arabian Peninsula and spans multiple countries, including Saudi Arabia, Yemen, Oman, the United Arab Emirates, Qatar, Kuwait, and parts of Jordan and Iraq. Saudi Arabia contains by far the largest portion of the desert's area.

The Arabian Desert covers approximately 2.3 million square kilometers, making it roughly one-fourth the size of the Sahara, which spans about 9.2 million square kilometers. Both are among the largest deserts in the world, though the Sahara remains the largest hot desert on Earth.

The Arabian Desert is one of the hottest and driest regions on Earth, with summer temperatures frequently exceeding 50°C (122°F) in some inland areas. Annual rainfall is extremely low, often less than 100 millimeters per year, and the region experiences intense evaporation rates due to high temperatures and low humidity.
