Which terrain feature is characterized by a raised landform with steep sides?

The correct answer is a ridge, which is defined as a long, narrow raised landform with steep sides. Ridges are often formed by geological processes such as erosion and are typically found in mountainous or hilly areas. They can serve as natural barriers and are prominent features on topographic maps, indicated by contour lines that are close together, which represent the steepness of the terrain.

Understanding this terrain feature is essential for navigation and land use, as ridges can influence weather patterns and serve as vantage points for observation. The distinction of a ridge compared to other geological features clarifies why it is not a hilltop, which generally refers to the peak of a hill, nor a valley, which describes a low point between two higher areas. A saddle, on the other hand, is a dip or low area between two hilltops or ridges and does not have the steep sides characteristic of a ridge.
