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.
Therefore, the air pressure is lower. Air temperature changes as you go higher above the earth. Since the surface of the earth heats the air above it, the air is warmer near the ground. Air pressure on the earth's surface also changes. Changes in temperature cause changes in air pressure. As the air near the surface of the earth becomes warmer, the particles becomes warmer, the the particles of the air move farther apart. The air becomes lighter and rises. The lighter air pushes down on the surface of the earth with less pressure.
