expensive calculators have a “mode” button and there is an option where you can change “radians” to “degrees”. A 6 foot tall person in Davenport, Iowa has a shadow length at noon of 6/sin49 (recalling that our sun angle is 49⁰ in an above example) which is 7.95 feet long. Fill in the chart below. You may use your sun angles from the previous chart. Your location Sun is directly striking this latitude Shadow length for a 6 foot tall person 3a Murmansk, Russia, 68 degrees north latitude equator 16 3b Minneapolis, Minnesota, 44 degrees north latitude equator 8.3 3c Houston, Texas, 29 degrees north latitude equator 6.9 3d San Salvador, El Salvador, 13 degrees north latitude equator 6.2 4) We are now going to look at seasonal variation in sunlight strength. We will look at the length of a shadow once again, and this will give us a feel for how the sunlight spreads across the ground. The more the sunlight spreads across the ground, the weaker the sunlight is (the less energy we will get from the sun per unit area of the earth’s surface). 4a) Fill in this chart for shadow lengths.

Your location Sun is directly striking this latitude Shadow length for a 6 foot tall person Sun is directly striking this latitude Shadow length for a 6 foot tall person Murmansk, Russia, 68 degrees north latitude Equator First day of spring 16 Tropic of Cancer First day of summer 8.4 Houston, Texas, 29 degrees north latitude Equator First day of spring 6.9 Tropic of Cancer First day of summer 6 4b)Compare the two cities. In general, which latitudes do you see a greater seasonal variation in the strength of the sun (indicated by differences in length of shadows)? Which latitudes do you see less seasonal variation in the strength of the sun? Greater seasonal variation in the strength of sun causes greater seasonal variation in what?

    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.
