A peak that is taller than 1,000 meters is classified as a mountain. This definition helps distinguish mountains from lower elevations like hills. Mountains often feature diverse climates and ecosystems, and they are frequently characterized by steep terrain, rocky summits, and unique flora and fauna. Their formation can occur due to various geological processes, including tectonic activity and volcanic eruptions. Mountains play crucial roles in influencing weather patterns, watershed management, and as habitats for numerous species.
