👉 Fossage, in geological terminology, refers to the process of erosion and deposition of sediment. It occurs when water erodes rock over time, causing it to become loose or decompose. This can lead to the accumulation of sediment on the surface of a lake, river, or other body of water. Fossages are often characterized by their smooth, flat surfaces and can be found in all types of terrain, from mountainous regions to coastal areas.
