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. Escaping heat along these ridges causes hot water to circulate through the crust in a “hydrothermal system.” Webnoun. definition 1: the layer of the earth that lies between the crust and the core. The crust is the top layer of the earth--the layer we live on. The core is the center of our earth. The mantle is very thick and makes up most of the entire planet.
