2.  Discuss the energy-atmosphere system. Include in your discussion what you learned more about atmosphere and surface energy balances; global temperatures; and atmospheric and oceanic circulations. Also discuss how geoscientists study the planet to come to the conclusions they do. Finally discuss why you think it is significant to study these topics.

Note: This question asks you to summarize chapters 4, 5 and 6. Chapter 4 (“Atmosphere and Surface Energy Balances”) covers pathways for solar energy through the atmosphere, clouds, and energy interactions. Chapter 5 (“Global Temperatures”) covers the effects of latitude, elevation, cloud cover on global temperatures. Chapter 6 (“Atmospheric and Oceanic Circulations”) covers how the atmosphere and oceans circulate and interact to influence conditions on Earth.

I. Overview

IV. Atmospheric and Oceanic Circulations

·        Describe and discuss atmospheric circulations

·        Describe and discuss oceanic circulations
