1.Read and understand the text. Then, answer the questions that follow.
The atmosphere is composed of different levels. The first level, called troposphere, is the nearest to Carth, about 11
km 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 absorbs the most of the harmful ultraviolet radiation from the sun.
The mesosphere is above the stratosphere in which the atmosphere is very rarefied and the temperature 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 the thermometer. Temperature may be thousands of degrees high. The second to the last is
the exosphere, the region beyond the thermosphere. Finally, the ionosphere overlaps the other layers from above
the Earth. The air is ionized 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.
