Biology 220 – Recitation 4 – 10/02/07 Answer the following questions before class 1. Which city receives more intense solar radiation, Erie PA or Tampa, FL? Why? * Tampa, Fl – Tampa receives for intense solar radiation because it is closer to the equator than Erie is and the closer a location is to the equator, the intensity of solar radiation increase. Intensity is the greatest at the equator because the angle at which the light hits the equator is very sharp (near 90 degrees) and the light will not be deflected off of the Earth’s atmosphere as much as it will if it hits Erie. Since Erie is much farther north of the equator in the northern hemisphere, when light hits Erie, much of it is dispersed through deflection due to the angle at which the light hits the atmosphere and surface. Angle of incidence. 2. What causes seasons? Tilting of the earth toward sun (summer), tilting away (winter) A beam of light (heat) that is concentrated will provide more light (heat) than one that is more dispersed. When the flashlight is directly overhead, isn't the beam of light (and heat) more concentrated than when the
