  5. The temperature here can rise to 1,727 °C.

  6. The exosphere is mainly composed of hydrogen and helium.


5. Reading the text.

SS read the text about the atmosphere and complete the text with an appropriate sentence from the video.


The outermost layers of Earth are the atmosphere, hydrosphere, and biosphere.

Our atmosphere is unique in the solar system. The atmosphere is the thin, gaseous envelope that surrounds Earth. Air is the mixture of gases that is composed of 78 % of nitrogen, 21% of oxygen, 0.93% of argon, 0.039%  of carbon dioxide, and small amounts of other gases. All of these gases combine to absorb ultraviolet radiation from the Sun and warm the planet’s surface through heat retention.

1) __________________________________________________________________.

The atmosphere is divided into the following layers: troposphere, stratosphere, mesosphere, thermosphere, exosphere. The troposphere is the lowest layer of the atmosphere. There is air here.

2) _________________________________________________________________.

The troposphere begins at the surface and extends to between 7 km at the poles and 17 km at the equator. This part of the atmosphere is the most dense. The temperature drops from about 17 degrees C to -52 degrees C. The troposphere is known as a weather layer, as the clouds and fogs appear and the weather is formed.

3) __________________________________________________________________.

The overlying layer is the stratosphere, which extends to about 50 km above the surface.

Compared to the troposphere, this part of the atmosphere is dry and less dense. The temperatures in this region increases gradually to -3 degrees C. The stratosphere is important because it contains the ozone layer. This layer absorbs much of the sun’s stronger ultraviolet rays. Many airplanes fly in the stratosphere because it is very stable.

The mesosphere extends to 85 km. The temperature there again as low as -93 degrees C.

4) __________________________________________________________.

This is the layer where most meteors burn up entering the atmosphere.

The top of the mesosphere called mesopause is the coldest part of the Earth's atmosphere. The thermosphere extends up to 600 km. There is the highest temperature in this layer that is why it is called thermosphere.

5) __________________________________________________________________

The temperature here can rise to 1,727 °C.

The thermosphere is a layer with auroras. Aurora is an interesting phenomenon; it is a polar light in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. The thermosphere is divided into the ionosphere and exosphere.

The ionosphere contains a high concentration of electrically charged particles (ions); these particles are responsible for reflecting radio signals important to telecommunications.

The exosphere is the outermost layer of Earth's atmosphere. Here the particles are so far apart that they can travel hundreds of km without colliding with one another.

6) __________________________________________________________.

The exosphere is mainly composed of hydrogen and helium.
