The document defines coasts as the area where land meets the sea, and explains that coasts are important habitats and home to most of the world's population. Coasts are dynamic systems that are constantly changing due to coastal processes like waves and tides, which erode, transport, and deposit material, affecting both the environment and people living in coastal areas. The document will study waves, coastal processes and how they form landforms, coastal management, and possibly coral reefs.
