A Mountain Massif is a large, compact group of mountains or a mountain range that is characterized by its rugged terrain and significant elevation. These formations are often made up of several peaks and ridges, which can be formed through geological processes such as tectonic activity, erosion, and volcanic activity. Mountain massifs can be found all over the world, with notable examples including the Alps in Europe and the Rocky Mountains in North America. They play a crucial role in influencing local climates, ecosystems, and water sources, making them important for both natural environments and human activities.
