A coastal environment is the transitional zone where land meets a large body of water, characterized by dynamic physical and biological processes. These areas are highly energetic, shaped by forces such as wave action, tidal cycles, and littoral currents, which drive continuous processes of erosion and sedimentation. Ecologically, coasts support unique ecosystems, including salt marshes, mangroves, and coral reefs, which are adapted to salinity gradients and fluctuating water levels. Geomorphologically, the composition of a coast varies widely, ranging from rocky headlands to depositional beaches, and the specific physical characteristics largely determine the biodiversity and resource value of the area.
