Have you ever watched a group of birds flying together in a big V shape? This is called a convergence movement, and it happens when many individuals come together and move in the same direction.
In other words, convergence movement is when a lot of things come together and start moving in the same way. This can happen with all sorts of things, like people, animals, or even ideas.
For example, think about a big group of people walking down the street together. They might start out in different places or at different times, but eventually, they all end up going in the same direction. That's a convergence movement!
Another example is when a group of animals like fish or birds all swim or fly in the same direction. They might do this to avoid danger or to find food. When they all move together like that, it's a convergence movement.
Basically, convergence movement is when lots of things come together and move in the same way. It's like a big group of friends all walking to the park together - they have different starting points, but they all end up in the same place, going in the same direction.
