Webuse of upward convection currents heat transfer gsu - Apr 22 2024 web heat convection convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat carrying energy with it convection above a hot surface occurs because hot WebConvection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known …
WebConduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles release electromagnetic radiation, which can be felt as heat. Sort by: Top Voted Questions Tips & Thanks WebFeb 3, 2016 · Explanation: Convection currents are an important form of heat transfer. Convection occurs when heat cannot efficiently be transferred through radiation or thermal conduction. In astronomy convection …
WebThis occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow. At the crest of the uplift, the overlying plate is stretched thin, breaks and pulls apart.
