It is known as “the great desert” in Arabic. It is about 9 million square kilometres in size and is one of the oldest places on Earth. Most of the Sahara is rocky ground, but there are also sand seas. When the wind blows, the sand looks like waves. Life here is difficult. People move from place to place to find water. Animals like camels and fennec foxes have adapted to survive the heat. Sadly, the Sahara is growing because of climate change. As temperatures rise, less rain falls, and the ground becomes drier and drier. If we do not take effective measures, the desert will keep growing. We need to act now to protect our planet. 1 学科网（北京）股份有限公司 $
