Activity 3. DIRECTIONS: Read the text below. Then, answer the questions that
follow.
The atmosphere is composed of different levels. The first level, called
troposphere, is the nearest to the Earth, 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 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 maybe a thousand 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.
