☑️ VERIFIED ANSWER
1.) 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.
2.) Erosion is typically driven by the action of waves and currents, and by mass wasting processes on slopes, and subsidence (particularly on muddy coasts). Significant episodes of coastal erosion are often associated with extreme weather events (coastal storms, storm surge and flooding) but also with tsunami.
3.) Environmental impacts from erosion include the destruction of animal habitats and esthetic losses. Fishing industries that are dependent on coastal habitats can suffer great economic impacts from changes caused by coastal erosion, and the loss of tourism can result in similar repercussions.
4.) The effects of climate change could be devastating to vulnerable coastal and marine areas as well as to the function and structure of their ecosystems. Increasing sea level (1,7 mm/year) changes the shape of coastlines, contributes to coastal erosion and leads to flooding and more underground salt-water intrusion.
5.) Reclamation usually leads to the decline of biological diversity, the decrease of natural wetlands, and the extinct of habitats for animals and plants. For migratory species, the living environment of marine plants and marine animals has been seriously affected.
Explanation:
Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and/or sands along the coast.
