A

Troposphere

38
Q

At the stratopause, the temperature stops ______ with altitude.

A

increasing

39
Q

Why does the overlying mesosphere have a decreasing temperature with altitude?

A

increase

thermosphere

41
Q

solar radiation

heats

42

A

thin

43
Q

45
Q

What is the approximate height and temperature of the tropopause?

A

12-20 km; -56 degrees C

46
Q

What is the approximate height and temperature of the stratopause?

A

48-52 km; -2 degrees C

47
Q

What is the approximate height and temperature of the mesopause?

A

84-92 km; -86 degrees C

48
Q

The lower stratosphere is cold at about _____ degrees Celsius.

A

-60

49
Q

Why is the upper stratosphere warmer than the lower stratosphere? And, what causes that?

A

The upper stratosphere contains a layer of ozone.

The ozone in the stratosphere absorbs energy from the sun which is converted into heat and warms the air.
