Compare convection inside Earth with convection in the atmosphere. How are they similar? How are they different?

Convection in both places includes sinking of colder and denser materials and rise of warmer and less dense materials. In both cases, convection transports heat. The biggest difference is the rates of convection, which are on the order of centimeters per year inside Earth whereas wind moves at speeds up to meters per second.
