A confluence point is where two or more streams or rivers come together and meet. Imagine you have two small rivers that are flowing down from different places and when they finally get close to each other, they join together to make a bigger river. This meeting point is called a confluence point. It's like when you have two friends and they both come to your house at the same time to play. Instead of having two separate games, you all decide to play one big game together. That's like the rivers at the confluence point joining forces to become a bigger, stronger river.
People who study maps really like confluence points because they can be very interesting and important places. Sometimes people even use them to decide where to build cities or dams. Overall, confluence points are where two or more rivers come together and it's a really cool thing to see!
