The atmosphere is composed of interent levels. The first lovol, called
troposphere, is the nearest to Earth, about 11 thick. Most clouds and weather
are found in this layer. Next is the stratosphere which is about 11-48 km above
the Earth's surface. In it is the ozone layer which absorbe the most of the harmful
ultraviolet radiation from the Sun. The mososphere is above the stratosphere
in which the atmosphere is very rarefied and the temperaturo decreases with
altitude. The fourth layer is the thermosphere which starts at about 55 km. The
temperature is so hot that it cannot be measured by a thermometer. Temperature
may be thousands of degrees high. The second to the last to the exosphere,
the region beyond the thermosphere. Finally, the lonosphere overlaps the other
layers from above the Earth. The air is iortized by the Sun's ultraviolet rays.
These ionized layers affect the transmittance and reflectance of radio waves.
All in all, there are six levels of the Earth's atmosphere.
