Beach cusps

Okay kiddo, have you ever been to the beach and noticed those little bumps of sand that look like upside-down U shapes? Those are called beach cusps! But why do they form? Well, it's all about the water and the sand. Waves come crashing onto the shore and they wash up the sand. But some places on the beach get more water than others. When that happens, the sand gets pushed around and eventually forms the beach cusps.

Think about when you're playing in the sand at the beach. If you dribble water onto your sandcastle, it makes the sand all wet and it runs down the sides of the castle. If you dump more water in one spot than another, it creates these little canals where the water flows. Now imagine this happening on a giant scale with waves constantly coming in and out. That's how beach cusps form!

And do you know why they are important? They actually help keep the beach stable! The cusps help control the currents of the water and stop too much sand from getting washed away. Plus, they look really cool too! So next time you're at the beach, see if you can spot any beach cusps and impress your friends with your beach knowledge!
