How does air get heated up?
Energy is transferred by one of three mechanisms: radiation, convection or conduction. Radiation is the transfer of energy (either outer space or the atmosphere) through waves. Convection is the transfer of energy through hot and cold cells through fluids (air or water). Conduction is the transfer of heat through solids (and possibly fluids) due to atomic and molecular collisions. Of the three methods, conduction has the least to do with heating the atmosphere.
The sun transfers electromagnetic radiation (infrared radiation or heat) across the void of space and through the atmosphere, hydrosphere and continents by radiation. Through a process called "Global Warming", some of this radiation is absorbed while some of it is reflected back into space.
The heated atmosphere and hydrosphere then transfers this energy through convection, since cold fluids fall (being more dense) and hot fluids rise (being more dense).
Finally, some of this energy is absorbed into the solid parts of the Earth and it is conducted to other parts of the Earth that are not as hot.
