What term is used to describe an elevated landform that rises sharply above its surroundings?

The term used to describe an elevated landform that rises sharply above its surroundings is "Mountain." Mountains are characterized by significant elevation and steep slopes relative to the surrounding terrain. They are typically formed through tectonic forces, volcanic activity, or erosion, resulting in prominent peaks or ranges.

In contrast, hills are usually smaller and have gentler slopes, while ridges are long, narrow elevated landforms that can connect several peaks. Plateaus are flat or gently sloping areas that rise significantly above the surrounding landscape but are not defined by sharp elevation changes. Therefore, "Mountain" is the most suitable term for a landform that rises sharply above its environment.
