Also question is, what is convection in simple words?
Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection currents within the earth move layers of magma, and convection in the ocean creates currents.
Beside above, what is convection kid definition? Kids Definition of convection : motion in a gas (as air) or a liquid in which the warmer portions rise and the colder portions sink Heat can be transferred by convection. convection. noun. con·?vec·?tion | k?n-ˈvek-sh?n
Besides, what are three types of convection?
Because of convection! There are three types of heat transfer: conduction, convection and radiation. Convection is a type of heat transfer that can only happen in liquids and gases, because it involves those liquids or gases physically moving.
How does a convection current work?
Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. For instance, a hot radiator heats the air immediately around it.
