What is a land depression?

A land depression is a landform that lies below the surrounding terrain. Depressions can be either natural, such as valleys and canyons, or man-made, such as quarries or mines. They can be of various shapes and sizes, ranging from small, localized depressions to large features such as basins or deserts. Depressions can be formed by a variety of processes, including erosion, tectonic activity, and subsidence. Over time, land depressions can fill in with sediment or water, creating new landforms.
