Major Deserts Beyond the Sahara: A World Tour

Deserts cover ~33% of Earth's land. Beyond the Sahara, key examples:

1. Arabian Desert (2.3M km²) — Arabian Peninsula. Hyper-arid, vast dune seas (Rub' al Khali), extreme heat.
2. Atacama Desert (105,000 km²) — Coastal Chile/Peru. World's driest non-polar desert (<1 mm/yr in core). Fog-dependent ecosystems.
3. Australian Deserts (1.4M km² combined) — Great Victoria, Great Sandy, Gibson, Simpson, Tanami. Red sands, spinifex, ancient weathered landscapes.
4. Gobi Desert (1.3M km²) — Mongolia/China. Cold winter desert (−40°C), rain shadow of Himalaya. Dinosaur fossils.
5. Mojave Desert (124,000 km²) — SW USA. Joshua trees, Death Valley (lowest/hottest in NA), Basin & Range topography.
6. Kalahari Desert (900,000 km²) — Botswana/Namibia/South Africa. Semi-arid savanna, fossil valleys, San people.
7. Patagonian Desert (670,000 km²) — Argentina/Chile. Cold, windy, rain shadow of Andes.
8. Great Basin Desert (490,000 km²) — USA (NV, UT, OR, ID). Cold, sagebrush, internal drainage.

Each has unique climate drivers (subtropical high, rain shadow, cold currents, continentality), landforms, and biota. All share aridity as the defining filter.
