All of the following are true of the Earth's climate except:
◦ cool air is more dense than warm air so it tends to sink toward the Earth's surface.
◦ warm air is less dense than cool air so it tends to sink toward the Earth's surface.
◦ a column of cool, dense air produces high pressure at the Earth's surface.
◦ the movement of air within the atmospheric convection cells generates the Earth's major wind belts.
◦ a column of warm, less dense air produces low pressure at the Earth's surface.
