Coasts are the areas where land meets the ocean or sea. They are dynamic environments shaped by waves, tides, and weather. Coasts can be sandy beaches, rocky cliffs, or marshy wetlands, each supporting unique ecosystems. Many people enjoy visiting coasts for activities like swimming, surfing, and beachcombing, making them popular vacation spots. Coasts also play a vital role in the economy. They provide habitats for marine life, such as fish and seabirds, and are important for industries like fishing and tourism. Additionally, coastal areas often have cities and towns that rely on their proximity to the water for trade and transportation.
