12.
Which layer of the atmosphere is the warmest?
(a)
13.
Which layers of the atmosphere decrease in temperature with an increase in altitude?
a)
the troposphere
b)
the cryosphere
c)
the stratosphere
d)
the thermosphere
14.
Why does the temperature change in the stratosphere with an increase in altitude?
a)
The Stratosphere is not able to absorb sunlight very well so it cools with increased altitude
b)
The Stratosphere contains ozone which traps sunlight so it warms with increased altitude
c)
The Stratosphere is closest to the Sun so it warms with increased altitude
d)
The Stratosphere contains the magnetic field so it warms with increased altitude
e)
The Stratosphere is affected by the Earth's temperatures so it cools with increased altitude
