What is cliff and erosion​

Answer 1

Answer:

Cliffs are usually formed because of processes called erosion and weathering. Weathering happens when natural events, like wind or rain, break up pieces of rock. ... Erosion is the process of transportation of this sediment. On sea cliffs, sediment becomes part of the seafloor and is washed away with the waves.

Answer 2

Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.[1][2][3] The landward retreat of the shoreline can measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes.[4] Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.[4]
