Which feature is indicated by a low point in the ground, often resembling a sinkhole?

A low point in the ground that resembles a sinkhole is referred to as a depression. This term is commonly used in geography and geology to describe areas where the ground has subsided or where there is a significant dip in the terrain. Depressions can vary in size and depth, and they may collect water, forming ponds or lakes. They are essentially the opposite of elevated features like summits or hills.

The other terms have distinct meanings that do not apply here. Elevation refers to a height or an increase in ground level, while a summit specifically denotes the highest point of a hill or mountain. A hollow, while it can imply a low area, does not carry the connotation of a significant dip or sinkhole as a depression does. Understanding these terms helps in recognizing and describing various geographical features accurately.
