I know the whole idea of continental drift but I’m confused on how we know what past continents look like. I’ve seen so many YouTube videos of Time-lapses of what the continents were like in a span of hundred of millions of years. But they’re always incredibly detailed and it had me wondering how we know all this. I heard people say we can get an estimate what the continents were shaped like based on what directions their moving today. But that method can only take you so far right? Are all those maps of Pangea just guesses?

Imagine cutting a cake in half. On the side of the left part you can see the top layer of icing, the next layer down is sponge, than a layer of cream, chocolate, more sponge etc. These layers on the left part correspond to the layers in the right part where you cut it.
Cliffs on the edges of continents have similar layers that correspond to each other suggesting that they were once joined before being ‘cut’ by plate tectonics.
