WitrynaCoasts are the meeting point of the land and sea and are an open system, with inputs (sediment), transfers (longshore drift), stores (beach) and outputs (water). Coastal processes are divided into two parts: Marine processes - offshore (water-based) Terrestrial processes - onshore (land-based) These processes are then sub-divided … Witryna14 wrz 2024 · Longshore drift affects beach erosion by causing waves to break more gently near the coast, which results in the sediment being deposited onshore instead of being washed out to sea. It is a continuous, seasonal, and global process that transports sediments from near shore to near-coastal regions offshore. 12把椅子 苏联电影 https://whimsyplay.com
