Mountain ranges are large chains of mountains that are typically formed by tectonic forces, such as the collision of continental plates. They can span vast distances and are often characterized by their unique ecosystems and diverse wildlife. Famous examples include the Himalayas, which are home to the world's highest peak, Mount Everest. These ranges not only shape the landscape but also influence climate and weather patterns in their regions. They provide habitats for various species and are popular destinations for outdoor activities like hiking and skiing. The Rocky Mountains and the Andes are other notable mountain ranges that attract adventurers and nature enthusiasts alike.
