Earth convection

WebThe tops of the mantle's convection cells drag the bottoms of the plates, making them move. This movement causes spreading in some places and subduction in others. -Earth's mantle is broken up into plates that float beneath the overlying lithosphere. The bottoms of the mantle's convection cells drag the tops of the plates, making them move. WebConduction, radiation, and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by …

WebConvection in the atmosphere plays a vital role in two further mechanisms - quite apart from the emission of longwave radiation - whereby energy is transferred from the Earth's surface to the atmosphere. The first is the transfer of 'thermal' energy (often referred to rather loosely as 'heat') by a combination of conduction and convection. 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 … something that costs less than a dollar https://joyeriasagredo.com
