Okay kiddo, a bight is a special word that we use to describe a bendy part of a coastline. It's like when you bend your arm or knee, the place where it bends is called a joint. Similarly, when the coastline makes a big curve into the land, we call that a bight. It's a bit like a little bay or inlet in the coastline.
Now, let's practice. Can you make a bight with your arm by bending it? Great job! Now you know what a bight is in geography too!
