Hint:

the Indian Ocean

Today we know that Earth’s surface is made up of 8 to 12 big plates (depending on how you define big) and 20 or so smaller ones, and they all move in different directions and at different speeds. [---1---] They bear only an incidental relationship to the landmasses that sit upon them. The North American plate, for instance, is much larger than the continent with which it is associated. It roughly traces the outline of the continent’s western coast (which is why that area is so seismically active, because of the bump and crush of the plate boundary), [---2---] Iceland is split down the middle, which makes it tectonically half American and half European. [---3---] And so it goes for most plates.
