Explain how continental drift is possible and why it happens?
In: Other
So the crust off the earth (the bit you stand on) is hard and is split into the big chunks called plates these sit on top of the mantle which is incredibly hot rock that is like an incredibly viscous (thick) liquid. The mantle thats closest to the centre of the earth is a lot hotter than the mantle near the crust and because heat rises they swap places. The hot mantle rises and cools and the cool mantle sinks and heats up, this causes a cycle which i think is called convection. When the rising mantle reaches the crust it pushes it a bit which unsettles the plate causing it to move over thousands of years. Hope this helps 🙂
