coastlines

Coastlines are the edges where land meets the sea, shaped by natural processes like erosion, sediment deposition, and tidal movements. They can vary greatly, featuring sandy beaches, rocky cliffs, or marshy areas. Coastlines play a vital role in ecosystems, providing habitats for wildlife and serving as important zones for human activities such as fishing, tourism, and transportation. They are also influenced by factors like sea level changes and geological activity. Understanding coastlines helps in managing natural resources and protecting communities against coastal hazards.
