Process of Heat Transfer EARTH 103: Earth in the Future

Air masses spread out laterally when they reach the tropopause. This air rises until it gets to the top of the tropopause, which is a bit like a lid on the lower atmosphere. It then diverges, with some of the air flowing north and some flowing south. As it rises and moves away from the equator, the air gets colder, water vapor condenses and ...

Jan 29, 2020 Beside above, how does the mantle move? Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and ...

Nov 10, 2004 The heat, which is vibrations of atoms in the solid pan, moves as a result of fast moving (hot) atoms bouncing off slow moving (cool) atoms, causing the slow atoms to move faster (heat up). So at the top of the asthenosphere, the hot rock flows along the bottom of the lithosphere, transferring its heat to the cold rocks by conduction.
