When a pot of soup is placed on a stove, the soup at the bottom of the pot is heated. As the soup warms up, it rises to the top of the pot. The cooler soup is more dense than the warm soup and begins to sink. This soup is then heated, and the process repeats. should suit pants have a break

WebConvection in the mantle is the same as convection in a pot of water on a stove. Convection currents within Earth’s mantle form as material near the core heats up. As the core heats the bottom layer of mantle material, particles move more rapidly, decreasing its density and causing it to rise. The rising material begins the convection current.

"WebThe mantle is generally considered to convect as a single layer (whole mantle convection) or, at most two (the standard geochemical model). However, the mantle is more likely to convect in multiple layers as a result of gravitational sorting during accretion and the density difference between the mantle products of differentiation.
