1 Heating of the Atmosphere Chapter 15 Section 2Heating of the Atmosphere
2 Energy in the Atmosphere Radiation is the transfer of energy as electromagnetic waves50% of the sun’s radiation is absorbed by the Earth’s surface.5% of the sun’s radiation is reflected by the Earth’s surface20% of the sun’s radiation is absorbed by ozone, clouds and atmospheric gas25% of the sun’s radiation is scattered and reflected by clouds and air
3 Energy in the Atmosphere Conduction is the transfer of thermal energy from one material to another by direct contactNear the Earth’s surface, air is heated by conductionConvection is the transfer of thermal energy by the circulation of movement of a liquid or gasConvection currents are caused by the unequal heating of the atmosphere
4 The Green House EffectThe greenhouse effect is the process in which the gases in the atmosphere trap thermal energyGlobal warming is a rise in the average global temperatureThe balance between incoming energy and outgoing energy is known as the radiation balance
