Beaches are natural landforms along the edges of oceans, seas, lakes, or rivers, characterized by sandy or pebbly shores. They are formed by the action of waves and currents, which shape the coastline over time. Beaches serve as popular recreational areas where people can swim, sunbathe, and engage in various water sports. Many beaches are home to diverse ecosystems, including dunes, tide pools, and marine life. They often provide habitats for birds and other wildlife. Additionally, beaches can be important for local economies, attracting tourists and supporting businesses such as hotels, restaurants, and shops.
