Tropical deserts are regions characterized by high temperatures and low rainfall, typically receiving less than 10 inches of precipitation annually. These deserts often feature sandy or rocky landscapes, with sparse vegetation adapted to survive in harsh conditions. Common plants include cacti and drought-resistant shrubs. The most well-known tropical desert is the Sahara Desert, located in North Africa. Other examples include the Kalahari Desert in Southern Africa and the Namib Desert along the Atlantic coast of Namibia. Despite their arid conditions, these deserts host unique ecosystems and wildlife adapted to thrive in extreme environments.
