Atmosphere

Question 1

What is the most abundant gas and then other gases in the lower atmosphere (troposphere) in percentages?

Answer 1

Nitrogen 78%, Oxygen 21% and 1% is water and carbon dioxide

Question 2

Thunderstorms develop to a greater height in the tropics because?

Answer 2

The tropopause is higher in the tropics.

Question 3

Stratosphere isn’t used in aviation. It includes the tropopause base and extends how far?

Answer 3

50km

Question 4

The height where temp ceases to fall is the ?

Answer 4

Tropopause

Question 5

Stratosphere is most stable and has few clouds. Why?

Answer 5

Because the environment no longer gets colder with height.

Question 6

Tropopause is an isothermal layer. What does that mean?

Answer 6

Temp remains constant

Question 7

Troposphere contains mostly water vapour and temp cools with height. True or False

Answer 7

True

Question 8

Does the stratosphere include the tropopause?

Answer 8

Yes, it extends from the base of tropopause to 50km

Question 9

As you move from the equator to the poles, the height of ? decreases and the temp increase?

Answer 9

Tropopause. Hint: the temp increases in the tropics (the tropopause is fattest around its belt being the equator)

Question 10

Why is there very little convection within the stratosphere?

Answer 10

Because the air at the top layer is warmer than the bottom.

Question 11

The temp of the tropopause is -40 over the equator and the distance is 18km. What is the temp and distance over the poles?

Answer 11

-80 degrees and 8km. Note the international standard average temp is -56.5 degrees.

Question 12

50% of the total mass of the troposphere is withing ? metres from the surface?

Answer 12

5,000metres
