The shore is the area where land meets a body of water, such as an ocean, sea, lake, or river. It is characterized by sandy or rocky beaches, dunes, and sometimes cliffs. The shore is influenced by tides, which are the regular rise and fall of water levels caused by the gravitational pull of the moon and sun. Shorelines can vary greatly in appearance and ecosystem. They may host diverse wildlife, including birds, fish, and marine plants. Human activities, such as tourism and fishing, often take place along the shore, making it an important area for both recreation and economic activities.
