âGypsumâs main benefit for our farm is to improve soil structure and plant health, which in turn gives us better yields,â he says. âFor the cost, it gives us a good value for our economic returnâabout 10 to 20%.â
By understanding the way temperature changes with altitude, we can learn a lot about how the atmosphere works. For example, the reason that weather takes place in the lowest layer is that the Earth's surface is the atmosphere's primary heat source.n some layers, temperature increases with altitude and in others it decreases. The temperature gradient in each layer is determined by the heat source of the layer. The different temperature gradients in each of the four main layers create the thermal structure of the atmosphere.
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the earth's surface, is called the exosphere.The red line on the figure below shows how temperature varies with height (the temperature scale is given along the bottom of the diagram).n this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5Â°C per kilometre. This change of temperature with height varies from day to day, depending on the weather.
