Ask students to share their responses, and discuss how the differences in water temperature resulted in the formation of a convection current. Explain that convection currents require a source of heat. WebWhat is Convection? Convection is the process by which less dense material rises and more dense material sinks. The former are said to be more “buoyant” than the latter, and …
WebConvection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. The next time you heat anything like soup or pudding in a pan you can watch the convection currents move in the liquid.
WebConvection Current. Thus, a convection current is formed and the saturated air–vapor mixture from the water surface moves upward, is cooled by contact with the colder cover, becomes saturated, and is partially condensed, forming a thin film that slides along the inside cover surface by gravity. From: Encyclopedia of Energy, 2004.
WebDefinition of Convection Currents. We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another. We can exemplify it by observing that we feel hotter when we place our hands above a campfire. This happens due to convection currents.
