Coastline of Wales

Imagine you have a very long piece of paper. This paper is the coastline of Wales - the part of the country that is next to the sea.

Now, if you take a closer look at this paper, you will see that it is not straight. It has many curves and bends, just like you see when you go to the beach. This is what makes the coastline of Wales so special - it has many different shapes and sizes!

Some parts of the coastline are very rocky and steep, with big cliffs that drop down into the water. Other parts are much more gentle, with small beaches and sand dunes.

One thing to remember is that the coastline is always changing. Waves and wind and rain all work together to shape the coastline. Sometimes the sea will create a new beach or carve a new cliff. Other times, the weather will erode away parts of the land, making the coastline smaller.

So, in summary, the coastline of Wales is a long, curvy piece of land that is next to the sea. It has many different shapes and sizes, from rocky cliffs to sandy beaches. And, it is always changing because of the forces of nature.
