WebMar 29, 2024 · The Definition of Convection. Convection is a method of thermal energy transfer where the transfer of heat occurs via fluid motion. This fluid motion is caused by the difference in density between hotter regions of the fluid and cooler regions. These motions are called ‌ convection currents ‌, and the convective movement of fluid continues ...

WebConduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles ... WebMay 22, 2024 · Conduction and convection are similar in that both mechanisms require the presence of a material medium (in comparison to thermal radiation). On the other hand they are different in that convection requires the presence of fluid motion. It must be emphasized, at the surface, energy flow occurs purely by conduction, even in conduction. WebAccretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. Upwelling beneath the spreading centers is the rising component of mantle convection. The hot material added at spreading centers cools down by conduction and convection of heat as it moves away from the spreading centers. boom boom geoffrion
