Deserts and Mountains

Passage

Deserts and mountains are some of the most fascinating and extreme environments on Earth. Deserts are defined by their low rainfall, which is usually less than 10 inches per year. They can be hot, like the Sahara, or cold, like the Gobi Desert. Despite their harsh conditions, deserts are home to a wide range of adapted plants and animals. Mountains, on the other hand, are elevated landforms, often with steep slopes. They are formed by tectonic movements, volcanic activity, and erosion. Some of the highest mountains, such as Mount Everest in the Himalayas, challenge climbers with their difficult terrain and extreme altitudes. Deserts and mountains, though inhospitable, offer unique ecosystems and hold important cultural, economic, and recreational significance for humans. They also contribute to the Earth's weather patterns and the distribution of life on the planet.
