Detailed explanation-1: -Convection currents tend to move fluid or gas particles from one place to another. These are created as a result of the differences occurring within the densities and temperature of a specific gas or fluid.
Detailed explanation-2: -Convection currents in the mantle occur due to density differences caused by variations in temperature and composition.
Detailed explanation-3: -Convection is heat transfer due to a density differential within a fluid. As water’s temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.
Detailed explanation-4: -Convection currents are movements of fluid caused by a temperature or density difference within a material. Convection currents are only seen in gases and liquids because particles within a solid are fixed in place. Warm air rising toward a house’s ceiling or attic is a simple example of convection currents.
Detailed explanation-5: -Natural convection. Forced convection.
