Latitude.
Which layer of the atmosphere contains more than 90% of all water vapour?
Troposphere.
The troposphere is the …
Part of the atmosphere below the tropopause.
By volume, what percentage of the air in the lower troposphere consists of water vapour?
0 - 5%.
What is the average height of the tropopause over the equator?
16 km
How is the boundary layer between troposphere and stratosphere called?
Tropopause

-75dc.
Why are indications about the height of the tropopause not essential for flight documents in the tropics?
The tropopause is generally well above the flight level actually flown.

Which one of the following statements applies to the tropopause?
It separates the troposphere from the stratosphere.
The tropopause is a level at which temperature ceases to fall with increasing height.
.
The average height of the tropopause at 50d N is about?
11km.

Is the following statement correct?
The layer just above the tropopause is absolutely stable.
Yes

Yes.
