Sun Rays
This is a photo of the sun's UV rays shining through pine trees across from Osprey Hall on campus. The rate that the solar energy (solar constant) shines onto Earth is approximately 1400 Wm-2. It is believed that it takes 8 minutes for the sun's energy to reach Earth's surface. The main purpose of the sun is warming Earth's biosphere through the process of radiation. Solar radiation can be found on the electromagnetic spectrum in the 400-700 nm range. The solar energy from the sun raises temperature during the day, which explains why the temperature drops a few degrees at night. Because the sun's UV rays effect temperature, the living habits of organisms are influenced. For example, phototrophs, such as the pine trees featured in this picture, rely on solar radiation for an energy source. Photosynthesis could not occur without sunlight. So essentially, the sun is not only responsible for warmth, but partially for the oxygen we breath.
