WebConvection is the exchange of heat energy by the development of a liquid (fluid or gas) between regions of various temperatures. Warm air is less thick than cold air, thus convection flows are created within the sight of a temperature angle. WebConvection is a way in which heat travels. It occurs when heat is transferred by the movement of liquids or gases. The other methods of heat transfer are conduction and radiation. citibank east los angeles https://ods-sports.com

WebOct 3, 2024 · 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. What causes convection currents in Earth’s mantle?

WebMay 19, 2024 · A convection current is a current in a fluid resulting from convection. When one part of a fluid is heated, the temperature difference causes the fluid to move in a current or defined... WebConvection Currents The heat from the core causes the mantle to be heated at its base. The hot rock rises gradually towards the crust. As it rises, it moves further away from its heat source at the core and starts to cool down. When it reaches the crust, it is forced out sideways because it cannot easily pass through the solid rock above it.

Webgenerated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart.. Where convection currents converge, plates move towards each other.. The movement of the plates, and the activity inside the Earth, is called plate tectonics.
