WebHot air doesn’t rise - HotTER air rises!! Pollev: Conduction only occurs in solids whereas convection only occurs in fluids. T/F-False: conduction occurs in any state of matter and between states of matter. - Convection can’t occur in liquids because the molecules in it can't do this - because they’re too tightly packed so they only have vibrational movement … WebThe heat driving mantle convection has three sources. "Primordial" heat (left over from the accretion and differentiation that led to the formation of Earth’s core) contributes 20 to 50% of the heat. Heating due to the decay of radioactive isotopes (mainly potassium, thorium, and uranium) contributes 50 to 80%.
WebJul 20, 1998 · convection, process by which heat is transferred by movement of a heated fluid such as air or water.
