A shoreline is the area where land meets a body of water, such as an ocean, lake, or river. It is a dynamic zone that can change with tides, waves, and weather conditions. Shorelines can be sandy, rocky, or covered in vegetation, and they are often popular spots for activities like swimming, fishing, and picnicking. The shoreline plays a crucial role in the ecosystem, providing habitat for various plants and animals. For example, seabirds often nest along the shore, while crabs and shellfish thrive in the intertidal zone. Protecting shorelines is important for maintaining biodiversity and preventing erosion.
