Web19 mrt. 2024 · The mantle is 3,000 km (1,900 mile) thick layer of rock. A wet mantle is one that contains a high proportion of water, and that water affects convection. Earth’s mantle contains a lot of silicate minerals, and they were molten during the Hadean. Water lowers the melting point of silicates, keeping more of the silicates molten. WebHot stuff on the surface of the Earth cools fast because air can carry away the heat pretty easily by convection. This heat is eventually radiated back to space. The outer core, on the other hand, touches the hot mantle. Due to the relatively small temperature difference, there's not much heat transfer to the mantle.
