It has mountains, rocky plateaus, and even rivers that only appear after rain. The highest point in the Sahara is Emi Koussi, a volcano in Chad, which rises to 3,415 metres. The weather in the Sahara is extreme. During the day, temperatures can reach over 50°C. But at night, it can drop below freezing. The desert gets very little rain—less than 100 millimetres per year in most areas. Despite the harsh conditions, many plants and animals survive in the Sahara. Camels are well-known for their ability to go without water for long periods. Fennec foxes have large ears that help them stay cool. Some plants have deep roots to find water underground. People also live in the Sahara. They are mostly nomads who move from place to place with their animals. For thousands of years, they have found ways to survive in this difficult environment. Scientists are still studying the Sahara. They have discovered ancient rock art that shows the desert was once green and full of life. Climate change has turned it into the desert we see today. 1.Where is the Sahara Desert located? 2.What is the highest point in the Sahara? 3.
