Dr. Moore and his team have learned from GPS data that two continents with an ocean between them have been moving toward each other. Some students living on the coast of one of these continents don’t understand what is happening and they are worried that the continents will run into each other. How could Dr. Moore explain to them what is happening?

Dr. Moore can explain that it is continental drift.

Explanation:

continental drift is the phenomenon due to which all the continents are moving towards each other, due to this continental drift stundents afraidthat some day these continents will collide leading to catastrophe.

But this is not gonna happen in a snap, this needs a lot of time, this will take hundreds of years and even more. So there is nothing to be afraid of till then humans will find some or the other way to manage this. Plus as I said this process is very slow so there are very less chances that this could lead us to any kind of chaos or anhilation.

(Btw, this isn't my work, it's just that someone already answered this same question, and they didn't answer yours so I thought I'd give it to you.)
