The geographical term that describes the area where land meets the ocean is called the coastline. Coastlines can vary significantly, featuring sandy beaches, rocky cliffs, or marshlands. They are dynamic environments where terrestrial and marine ecosystems interact, supporting diverse wildlife. Coastal zones often have rich biological diversity and are vital for human activities, including fishing, tourism, and transportation. The management of these areas is crucial, as they face challenges from climate change, erosion, and human development.
