Question
Explain the embarrassment cover.
✓
Answer
The first layer of the atmosphere starting from the earth's surface is called the turbulence layer.
The cover extends to a height of $16 \ km$ on the tropics, $12 \ km$ on the temperate regions and about $8 \ km$ on the polar regions.
Another notable aspect of this cover is as follows.
$(1)$ Atmospheric storms, movement of air, lightning, clouds, rain as well as whirlwind are felt in this cover.
$(2)$ The air temperature decreases as we get higher from this cover.
$(3)$ The upper surface of the turbulence cover where the temperature stops falling is called the "turbulence limit".
The air temperature in this border area remains almost constant.
$(4)$ The movement of air in this area also slows down.
Therefore, this area is considered very suitable for the flight of aircraft.
