Chapter 11 : The Earth’s Global Energy Balance
Pages : 212
PREVIEW
1. What will this chapter cover? (What important ideas will be covered?)
This chapter will talk about where the earth’s energy that powers all life process in our planet comes from, how the earth absorbs the energy, what is the process that of greenhouse effect, and how does the earth manage to balance the energy.
2. List five (6) major topics that will be covered in this chapter. Explain important details in each topic.
a. Topic : Electromagnetic Radiation
Details : Radiation and temperature, solar radiation, characteristic of solar energy, long-wave radiation from the earth, and the global radiation balance.
b. Topic : Insolation Over the Globe
Details : Daily insolation through the year, annual insolation by latitude, and world latitude zone.
c. Topic : Composition of the Atmosphere
Details : 97% air, mostly gases such as oxygen, nitrogen, carbon dioxide, and water vapour.
d. Topic : Sensible Heat and Latent Heat Transfer
Details : Heat storage and transfer, hidden heat, and flow of heat between earth surface and atmosphere.
e. Topic : The Global Energy System
Details : Solar energy loses in the atmosphere, albedo, counterradiation and the greenhouse effect, global energy budget of the atmosphere surface, climate, and global change.
f. Topic : Net Radiation, Latitude, and Energy Balance
Details : Net radiation, solar energy input, energy surplus, and poleward heat transfer.
