A chain of mountains, also known as a mountain range, is a series of peaks or ridges that are connected by high ground. These formations are typically created by tectonic forces, such as the collision of Earth's plates, which can cause the land to uplift and form mountains. Mountain ranges can vary in size, length, and elevation, and they often serve as natural barriers and habitats for diverse ecosystems. Some well-known examples of mountain chains include the Himalayas, which are home to the world's highest peak, Mount Everest, and the Rocky Mountains in North America. Mountain ranges can influence climate patterns, affect local weather, and provide recreational opportunities for activities like hiking, skiing, and climbing.
