Facts About Convection Currents. The movement of the currents plays a factor in the movement of the mantle. In astronomy convection currents occur in the mantle of the Earth and presumably some other planets and the convection. Convection currents transfer heat from one place to another by mass motion of a fluid such as water air or molten rock. The cold air being dense sinks and is taken into the.
The basic principle of a convection current is that warm air rises because of the extra energy it received in the form of heat and cold air falls because of the low energy state. Convection is one among the forms of heat transfers of which the other two are radiation and conduction. Convection currents occur when there are significant differences in temperature between two parts of a fluid. Even the radiators work on the principle of convection. Because particles within a solid are fixed in place convection currents are seen only in gases and liquids. Just like the example of air-conditioners above the radiators also work in a similar fashion.
Tectonic plates move in different directions.
Convection Currents Convection Currents Heat energy transfer between two parts A of a fluid of different temperatures When hot fluids rise and cold fluids sink Occurs in the atmosphere A Occurs. The cold air being dense sinks and is taken into the. Convection currents that occur within the molten rock in the mantle act like a conveyor belt for the plates. Convection occurs when heat cannot efficiently be transferred through radiation of thermal conduction. We can see these convection currents in air and in water. Convection currents are an important form of heat transfer.
