  • Beach Morphology

    1847 Words  | 8 Pages

    Beaches are coastal landforms that are constantly changing. They are the result of wave action by which waves move sand or other loose sediments and compact and settle in still water. Beach materials are the products of weathering and erosion of rocks offshore, coral reefs and of headlands. Sediments may also be river-borne through the process of coastal erosion. Once compacted, the accumulated sediments are more resistant to erosion. Vegetation establishes shortly after, and their roots will also
