Sand deserts are vast, dry regions characterized by sandy terrain and minimal vegetation. They typically receive less than 10 inches of rainfall annually, making it difficult for most plants and animals to survive. The high temperatures during the day can exceed 100°F, while nights can be surprisingly cool. These deserts are often formed by wind erosion, which shapes the landscape into dunes and other unique formations. Notable examples of sand deserts include the Sahara Desert in Africa and the Gobi Desert in Asia. Despite their harsh conditions, some specialized species have adapted to thrive in these environments.
