\ Introduction to the Atmosphere (1) Starting at sea level, temperature steadily decreases while altitude increases throughout the troposphere. Here it remains constant until 20 km into the stratosphere where temperature begins to increase with altitude. This trend continues until 48 km or the bottom of the mesosphere. Then through the mesosphere temperature decreases with increasing altitude until it reaches a minimum at 80 km, or the top of mesosphere. Through much of the thermosphere it remains constant until temperature begins to increase until reaching 200 km. At ground level the prominent heat source is visible sunlight. Energy from the sun is absorbed by the lowest level of the troposphere. In the stratosphere the heat source comes from the warming of the atmosphere by ultra violet sunlight. The warm zone near the ozone layer absorbs the ultra violet rays and helps to warm the atmosphere. Finally in the thermosphere, atoms and molecules absorb the same ultra violet rays causing them to split giving off energy and acting as a heat source for the layer. (2)
