Question

Name the five layers of atmosphere that are considered to play main role in

communication. Write the approximate height from the surface of the earth,

frequency range and functions of these layers.​

Answer 1

Answer:

troposphere

stratosphere

mesosphere

thermosphere

exosphere

Explanation:

The TROPOSPHERE is the lowest layer of our atmosphere extending up to about 15 kilometers above the surface of the earth. This is the Lower Atmosphere.

The STRATOSPHERE is the layer above the troposphere, extending from about 15 to 50 kilometers up. The much talked about OZONE LAYER lies in this region of the atmosphere.

The next layer is the MESOSPHERE extending from about 50 kilometers  to 80 kilometers up.  "Meso" in Greek means "middle". Again, the temperature decreases as we go higher in this region of the atmosphere.

Next comes the THERMOSPHERE, extending from about 80 kilometers to about 500 kilometers.  Strangely, the temperature here is quite high - as we can understand from the name - it can reach up to 2000°C in this region.

The topmost layer of the upper atmosphere is the EXOSPHERE, from where the lighter atoms and molecules escape into space. EXO in Greek is "outside" or "beyond". This layer, being the outermost, starts at around 500 kilometers up and extends up to almost 10,000 kilometers into space.

Answer 2

Answer:

The five layers of atmosphere are :-

1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
5. Exosphere

Troposphere

Explanation:

It is extending up to 15 on above the earth ' s surface. Most clouds are formed within the troposphere.

Stratosphere

It is extending up to 15 to 50 km above the earth ' s surface . It contains a thin layer of ozone that absorbs most of the harmful ultraviolet radiator .

Mesosphere

It is extending up to 80 km above the earth ' s surface. All the heavenly bodies like meteors slow down in this layer and burn up , leaving fiery trails in the sky .

Thermosphere

It is extending up to 80 to rep km above the earth ' s surface. It receives extraordinarily large amounts of energy from the sun .

Exosphere

It is the uppermost layer of the atmosphere. It is the layer where atmosphere merges into the space .
