What is a ridge line?

A ridge line is defined as a line of high ground where the elevation changes, creating a distinct topographical feature. This term is commonly used in geography and outdoor navigation to describe the crest of a series of hills or mountains. The significance of a ridge line lies in its ability to serve as a natural boundary or a point of reference for navigation, making it essential for hikers, hunters, and military operations to understand the terrain.

In contrast, other options describe different geographical features. A low-lying area between hills refers to a valley, while a body of water would typically pertain to lakes, rivers, or oceans. A flat plain describes an area of land that is mostly level and does not contain the significant elevation changes associated with ridge lines. Understanding these distinctions helps clarify the unique characteristics of a ridge line in the context of the broader landscape.
