The **Sahara Desert** is characterized by a **hot desert climate**, featuring extremely low annual rainfall and high temperatures during the day. Nights can be surprisingly cold due to the lack of moisture in the air. This climate leads to unique adaptations in both the flora and fauna that inhabit the region, such as cacti and various animal species that can withstand harsh conditions. The Sahara is the largest hot desert in the world, spanning several countries in North Africa and shaping the lives of the people who live in and around it.
