What is a ridge in geographical terms?

A ridge, in geographical terms, is defined as a long, narrow hilltop or mountain range. This feature typically consists of elevated terrain that extends over a significant distance, often characterized by its linear form and steep slopes on either side. Ridges can be formed through various geological processes, including tectonic activity, erosion, and sediment deposition. They are commonly found in mountainous regions and can serve as natural boundaries and habitats for diverse ecosystems.

The other options describe different geographical features: a low flat area of land refers to plains or plateaus, a waterway or brook is associated with bodies of water, and an urban development zone pertains to human-made environments, none of which align with the definition of a ridge. Understanding ridges is important in geography as they can influence weather patterns, ecosystems, and human settlement patterns, making the identification of such features essential in both academic and practical applications of geography.
