The Sahara Desert is located in Africa and is considered the world's hottest desert. Spanning across several countries, its vast expanse is marked by extreme temperatures, particularly during the day, where they can soar above 50 degrees Celsius (122 degrees Fahrenheit). The Sahara features a diverse landscape that includes sand dunes, rocky plateaus, and oases. Its extreme climate and conditions contribute to a unique ecosystem, despite the harsh environment, which sustains various plants and animals adapted for survival in such an arid region.
