Select one of the following:

  • The line where the temperature no longer decreases with increase of
    height.

  • The layer between the tropopause and the stratosphere

  • The layer beyond which only CI cloud occurs.

Question 3 of 15

1

One of the most important characteristics of the atmosphere is:

Select one of the following:

  • Density is constant above 10000 ft

  • The air is a poor conductor of heat

  • Temperature lapse rate is very frequently above 3ºC per 1000 ft.

Explanation

Question 4 of 15

1

Most of the vapour in the atmosphere is contained in the:

Select one of the following:

  • tropopause

  • stratosphere

  • troposphere

  • stratopause

Explanation

Question 5 of 15

1

The captain of an aircraft needs to know the height of the tropopause because:

Select one of the following:

  • it normally represents the limit of weather

  • density starts to increase

  • there are no longer jet streams and CAT

  • it indicates the height of the thermal wind

  • troposphere

  • mesosphere

  • stratosphere

Explanation

Question 7 of 15

1

increase in height is known as:

Select one of the following:

  • The troposphere

  • The stratopause

  • The stratosphere

  • The tropopause

Explanation

Question 8 of 15

1

Which statement is correct when considering the lower layers of the atmosphere:

Select one of the following:

  • the majority of the weather is contained in the stratosphere and its upper
    boundary is the tropopause

  • the majority of the weather is contained in the troposphere and its
    upper boundary is the tropopause

  • the majority of the weather is contained in the tropopause and its upper
    boundary is the troposphere

  • the majority of the weather is contained in the troposphere and its upper
    boundary is the stratosphere

Explanation

Explanation

Question 11 of 15

1

The international (ICAO) Standard Atmosphere assumes that the sea level
atmospheric pressure is:

Select one of the following:

  • 1013,25 mbs and decreases with an increase in height.

  • 1013,25 mbs and increases with an increase in height.

  • 1013,25 mbs and falls to about half this value at 30000 ft

  • 1013,25 mbs and decreases with an increase in height up to the
    tropopause. Above the tropopause it remains constant.
