WebMantle convection is the main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid-ocean ridge system is in essence a 80,000 km long volcano.

As we read before, crust can be divided into two different types, continental and oceanic crust. Both types “float” on the denser mantle. Continental crust is about 25-90 km (15-55 mi) thick and divided into tectonic plates. These plates move slowly (just a few centimeters) each year over the more fluid mantle. cis ardmore okWebThe movement of the mantle is the reason that the plates of the Earth move!
