A hot desert is a dry, arid region 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 extreme conditions, such as cacti and drought-resistant shrubs. The climate in hot deserts, like the Sahara Desert or the Sonoran Desert, can reach scorching temperatures during the day, often exceeding 100°F (38°C). Nights can be much cooler, leading to significant temperature fluctuations. Wildlife in these areas, including reptiles and small mammals, has adapted to survive with limited water and extreme heat.
