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.
Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5 C with each increase in altitude of 1 kilometer (about 3.6 F per 1,000 feet).The rate at which the temperature changes with altitude is called the lapse rate.n the layer above the troposphere, the stratosphere, temperature rises with increasing altitude. In the stratosphere, the air is heated from above by ultraviolet light which is absorbed by ozone molecules in the air. The tropopause is the boundary between the troposphere (below) and the stratosphere (above).
