(B) Troposphere
C) Mesosphere
(D) Exosphere​

Answer 1

Answer:

meosphere...............

Answer 2

The layer that helps in wireless communication is the Thermosphere(not mentioned in options)

There are different layers in the atmosphere with different densities.

The atmosphere is divided into 5 different layers depending on the temperature

The Troposphere

• Lowest part of earth's atmosphere.
• In this layer all tropical changes take place.
• Dust particles and water vapor are present in this layer
• This layer is subjected to the change in weather and climate
• Tropopause is the region separating the Troposphere from the stratosphere

The Stratosphere

• It has a height of 50 km
• One of the important features of this layer is that the ozone layer is present in the Stratosphere
• The ultraviolet radiations are absorbed by this layer and thus protect our life on the earth from the harmful source of energy

The Mesosphere

• It has a height of 80km

• In this layer when the height increases the temperature decreases
• And thus it reaches at minus 100°C at a range of 80 km

The Thermosphere

• It is located at the range of 80km to 400km
• The electrically charged particles ions are present in this area
• Hence it is also known by the name Ionosphere
• Radio waves are transmitted through this layer
• This layer helps in wireless communication
• When the height increases the temperature also increases

The Exosphere

• The outermost  layer and is the highest layer
• The matters in this layer are rarefied and merge with the outer space
