What type of boundaries do relict features often have?

Relict features are geological or geomorphological remnants that have survived changes over time and typically indicate former environmental conditions. These features often exhibit abrupt boundaries, which means there is a clear and distinct separation between the relict feature and the surrounding landscape. This sharp contrast is usually due to the processes that formed the relict, which may be significantly different from current processes. For instance, a former river channel can be distinctly visible from the surrounding terrain because of differences in soil composition, elevation, or vegetation.

Recognizing these abrupt boundaries is essential for soil evaluators, as it can provide valuable insights into the historical land use and environmental changes that have occurred in an area. Such understanding can inform decisions related to land management, conservation, and development.
