Convection is the movement within a liquid or gas driven by differences in temperature. Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink. (Met Office, n.d.)
