Abstract
Atmosphere is a body, which is composed of gasses. Those atmospheric gases are located around planets because of the gravitation forced applied. Our planet’s atmosphere consists of oxygen, nitrogen, carbon dioxide and other atoms and molecules. Although each layer of atmosphere has different qualities, the most important purpose of the atmosphere is to contain gases that are vital for living organisms. If we think about oxygen releasing unconditionally to the space, could we be able to breathe? In the experiment, which I designed, I have made a model of surface waters, sun and the atmosphere of Earth. The aim of the experiment was to observe the impact of the thickness of the layer to the temperature of the earth and surface water. To achieve this aim, I took glass rings with 5 cm diameter and 5 cm height and poured 5 cm water to another glass. After measuring initial temperature of the water, I turned the light on and waited 20 minutes and measured the final temperature of water. When I recorded 3 values for same height, I added one of the glass rings, I mentioned above, to the system and recorded another 3 trial values for initial and final temperatures. When I completed the experiment, I found out that there is an exponential decrease in the change of the temperature. This curved line was caused because after some height, the light bulb was not efficient and there were no difference between initial and final temperatures. When I ignored this systematic error, I assumed that the there was a constant but oppositely proportional relation between distance between light source and surface of water- temperature change of water.
