coast

• Human activities can also impact coastlines through construction, mining, agriculture, tourism, and pollution.
• Coastlines are dynamic features that change over time due to natural processes such as erosion, deposition, and weathering.
• The coastal zone is the area between land and sea, including beaches, cliffs, estuaries, lagoons, salt marshes, dunes, sandbars, tidal flats, and coral reefs.
• Coasts are vulnerable to various types of hazards, including storm surges, tsunamis, hurricanes, typhoons, cyclones, floods, landslides, earthquakes, volcanic eruptions, wildfires, oil spills, and chemical accidents.
• As waves approach the shore, they break against the beach or cliffs, causing erosion and shaping the coastline.
• Waves are formed when winds blow across open bodies of water, creating ripples on the surface.
• Beaches are formed when sand and other materials carried by rivers and streams deposit along the shoreline.
• The rate of coastal erosion varies depending on factors like wave energy, sediment supply, sea level rise, and human activity.
