The moment you arrive at the Sahara Desert in a geography book, education forms a closed loop!

When you see the Sahara Desert from your geography textbook with your own eyes, you will truly understand why people call it the 'King of Deserts'. At this moment, education completes its cycle, showing its true meaning. It is at this moment that you will understand the saying, 'It is better to travel ten thousand miles than to read ten thousand books.' The Sahara Desert formed about 2.5 million years ago and is the world's largest sandy desert, covering an area of about 9.32 million square kilometers, which is comparable to the land area of the United States. It stretches across 10 countries in North Africa. The climatic conditions in this region are extremely harsh, with daytime temperatures exceeding 50°C and nighttime temperatures not dropping below 20°C, making it one of the least hospitable places for life on Earth.
