In August, should the surface ocean water be colder off the coast of California or Massachusetts? Explain your reasoning. ___ / 10 points California is colder because it’s along the California current (5 pts) Massachusetts should be warmer because it’s along the Gulf Stream current Ø Gulf Stream current originates at lower latitudes that receive more solar radiation, making ocean water warmer Ø California current originates at higher latitudes where ocean water is colder (Explanation – 5 pts) 2. What is the infrared window, and why is it important to the Earth’s energy balance? Do greenhouse gases that absorb in this window have a larger or smaller effect than in other regions of the infrared region? Why? ___ / 15 points The infrared window is the portion of the electromagnetic spectrum (8-12 micrometers) where the % absorption by the earth’s atmosphere is low and transmittance is high (5 pts) This region allows infrared radiation to be transmitted to space with limited absorption by CO2 and H20. Necessary for earth to maintain energy budget (5 pts)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
