Coastlines

A coastline is where the land meets the sea. It is a dynamic and ever-changing boundary shaped by the interaction of land, sea, and natural forces such as waves, tides, and wind. Coastlines can be found all over the world and come in many different forms, including sandy beaches, rocky cliffs, and estuaries.

Formation of Coastlines

Coastlines are formed through a combination of geological processes and erosion. Some coastlines are created by the rise and fall of sea levels, while others are shaped by the movement of tectonic plates. Erosion by waves, wind, and water also plays a significant role in shaping coastlines over time.

Features of Coastlines

Coastlines can have a variety of features, including beaches, dunes, cliffs, sea caves, and coral reefs. These features are formed by the interaction of the land and sea, and each one has its own unique characteristics and ecological significance.
