A mountain range is a series of connected mountains that are typically formed by tectonic forces, such as the movement of the Earth's plates. These ranges can vary in size, height, and shape, and they often create distinct ecosystems and climates. Examples of well-known mountain ranges include the Himalayas, Rocky Mountains, and Andes. Mountain ranges can influence weather patterns and serve as natural barriers. They are often home to diverse wildlife and plant species, making them important for biodiversity. Additionally, mountain ranges are popular destinations for outdoor activities like hiking, skiing, and climbing, attracting many visitors each year.
