Desert landscapes are characterized by their arid conditions, receiving less than 10 inches of rainfall annually. These regions often feature vast stretches of sand dunes, rocky plateaus, and sparse vegetation, adapted to survive in extreme temperatures. Common plants include cacti and shrubs, which have developed unique adaptations to conserve water. The climate in deserts can vary significantly, with some experiencing scorching heat during the day and chilly temperatures at night. Notable deserts include the Sahara Desert in Africa and the Mojave Desert in North America. These landscapes are home to a variety of wildlife, including reptiles, rodents, and insects, all adapted to thrive in harsh environments.
