Hot deserts are arid regions characterized by high temperatures and low precipitation. They typically experience extreme heat during the day and cooler temperatures at night. The lack of moisture leads to unique ecosystems, where only specially adapted plants and animals can thrive. One of the most famous hot deserts is the Sahara Desert, which spans across several countries in North Africa. These deserts are not just barren landscapes; they are home to diverse wildlife and vegetation, showcasing nature's resilience in harsh conditions.
