Mountainous regions are areas characterized by high elevations and steep terrain. They often feature rugged landscapes, including peaks, valleys, and cliffs. These regions can be found on every continent and are home to diverse ecosystems, which support various plant and animal species. The formation of mountains typically occurs through tectonic processes, such as the collision of tectonic plates. This can lead to the creation of mountain ranges like the Himalayas or the Rocky Mountains. Mountainous regions also influence climate patterns, often resulting in cooler temperatures and increased precipitation at higher altitudes.
