Okay, let me try to explain what a tombolo is in a way that a 5-year-old will understand.
So, have you ever been to the beach and seen a little sand island that's connected to the shore by a narrow strip of sand? That's called a tombolo! It's like a bridge made out of sand that joins a little island to the beach.
You see, sometimes waves in the ocean can move sand around and build up a little sand island close to the shore. But then, the waves keep coming and they bring more sand with them. Eventually, the sand builds up so much that it connects the little island to the shore, creating a tombolo.
When you walk on a tombolo, it feels like you're walking on a little beachy path that's surrounded by water on both sides. It's really cool to walk on because you're walking in the middle of the ocean – well, kind of!
Tombolos are really special because they're pretty rare to find. They only form under certain conditions and not all beaches have them. So if you happen to see one, make sure you take a closer look and enjoy walking across it!
