👉 Effossion is a scientific concept in the field of geology, which refers to the formation and movement of sedimentary rock. It involves the accumulation of sand, silt, and gravel over time, resulting in the formation of layers that can be separated by various geological processes such as erosion, weathering, and glacial till. Effossion is a fundamental process in the Earth's geologic history and has been observed in numerous locations around the world.
