Coast: The boundary between land and sea. It includes the strip of land that borders the seashore. Seashore is the region where land meets the sea or ocean, or a line that forms the periphery between the ground and the sea or a lagoon. An accurate line that can be called a coastline cannot be indomitable due to the Coastline inconsistency.
The coast and its nearby areas on and offshore are a vital component of a local ecosystem: the combination of clean water and salt water (brackish water) in estuaries provides a lot of nutrients for sea life. Salt marshes and beaches also maintain a variety of plants, animals, and insects critical to the food chain.

Coasts aid us to realize innate events, such as climate and shifting sea levels. During storms, coasts are the initial places to be flooded. Some coasts have coastal plains. Coastal plains are pieces of horizontal, low-lying land that can become noticeable when sea levels begin decreasing.
