stratosphere Above the troposphere
ozone a molecule that is made up of three oxygen atom
radiation the transfer of energy across space and in the atmosphere
conduction the flow of heat from a warmer object to a colder object when the objects are placed in direct physical contact
convection the transfer of heat by air currents
greenhouse effect This process, in which gases trap heat near the Earth
water cycle The continuous movement of water into the air, onto land, and then back to water sources
evaporation the process by which liquid water is heated by the sun and then rises into the atmo- sphere as water vapor
condensation water vapor forms water droplets on dust particles
