Which landform is primarily characterized by its elevation and steep slopes?

Mountains are primarily characterized by their significant elevation and steep slopes. Unlike hills, which are generally lower and have more gradual inclines, mountains rise prominently above their surroundings, often reaching considerable heights. They are formed through geological processes such as tectonic activity, volcanic activity, or erosion over long periods, leading to their distinctive steep features.

In addition, mountains often create dramatic changes in climate and ecosystems due to their elevation, which can lead to diverse habitats. This elevation can also result in the presence of distinct vegetative zones at different altitudes, making mountains unique landforms in a geographical context.

Other landforms like plateaus, while elevated, tend to have more flat or gently sloping tops, and valleys are low-lying areas between higher landforms, which do not match the criteria of elevation and steep slopes associated with mountains.
