Question

108 Amount of Incoming Energy from the Sun (Sunlight)-342 Amount of Energy Esited by Earth's Surface that Goes Directly Out into Space 40 Amount of Energy Emitted by Earth's Atmosphere that Goes Directly Out into Space- 195 Amount of Sunlight Amount of Sunlight Reflectod by Earth'sReflected by Earth's Surface that Goes Directly Out into Space 30 Atmosphere that Goes Directly Back Out into Space- 77 Amount of Energy Emmited by Earth's Surface that is Absorbed by Earth's Atrsesphere 452 Amount of Sunlight Absorbed by Earth's Atmosphere 67 Amount of Energy Emittied by Earth's Atmosphere that is Absocbed by Eath's Amount of Sunlight Amount of Energy Sbsorbed by Earts Surface 168 Enuted by Earth's Surface-402 Figure 3 Figure 3 shows how light/energy flows through the Earth system for the "greenhouse effect. The numbers listed describe the amount of energy flowing through the system (units of watts per square meter), A larger number indicates that more energy is flowing through that labeled pathway. 12) How does the total amount of energy coming from the Sun compare to the total amount of energy leaving Earth to space? Provide numbers to support your answer. 13) What type of light primanily heats Earth's surface and where does this light come from? What type of light primarily heats Earth's atmosphere and where does this light come from?

Explanation / Answer

12.     Energy coming from the Sun :

(a)Amount of Incoming energy coming from the Sun (sun light ) 342 watts per square meter

Energy leaving Earth to space :

(a) Amount of sunlight reflected by earth's surface and goes directly out into space 30 watts per square meter

(b) Amount of sunlight reflected by earth's atmosphere that goes directly back out into space 77 watts per square meter

(c) Amount of energy emitted by the earth's surface that goes directy out into space 40 watts per square meter

(d) Amount of energy emitted by the earth's atmosphere that goes directy out into space 195 watts per square meter

13. The earth's surface heats light primarily comes from :

          (a) Amount of sunlight abosorbed by earth's surface 168 watts per square meter

         (b) Amount of energy emitted by the earth's atmosphere that is absorbed by the earth's surface 324 watts per square meter

    The earth's atmosphere heats light primarily comes from :

        (a) Amount of sunlight abosorbed by earth's atmosphere 67 watts per square meter

        (b) Amount of energy emitted by the earth's surface that is absorbed by the earth's atmosphere 452 watts per square meter
