You can observe convection currents in waterboilingin a pot. Simply add a few peas or bits of paper to trace the current flow. The heat source at the bottom of the pan heats the water, giving it more energy and causing the molecules to move faster. The temperature change also affects th...

Definition Convection currents are circular patterns that arise from the unequal heating and cooling of a fluid (gas or liquid). Features A convection current requires a heat source and a fluid that can circulate to transfer heat. In the atmosphere, the heat source is the sun and the fluid ...
Convection Currents in the Mantle - ScienceDirectdoi:10.1016/B978-0-12-395773-3.50008-5ELSEVIERDevelopments in Solid Earth Geophysics
What is the mantle ? Learn the mantle definition in earth science, facts about the mantle, and how the mantle is responsible for plate tectonics. Related to this Question What do mantle convection currents cause? What causes convection currents in the mantle?
The key part of this definition is that it is solely the transport of a material or quantity by the motion of a fluid, and so the advection geography definition depends strongly on wind currents or ocean currents. A warm ocean current, for example, moves higher-temperature water from one pl...
