5. High clouds are composed primarily of ice crystals, whereas low clouds are composed primarily of water
droplets. This difference is most likely because the
average air temperature at altitudes from:
A. 0 km to 3.2 km is at or below Or whereas the
average air temperature at altitudes Trom 3.2 km to
6.0 km is above 0°C.
B. O km to 3.2 km is at or below 0°C, whereas the
average air temperature at altitudes from 6.0 km to
16.0 km is above 0°C.
C. O km to 3.2 km is above 0°C, whereas the average
air temperature at altitudes from 3.2 km to 6.0 km
is at or below 0°C.
D. O km to 3.2 km is above 0°C, whereas the average
air temperature at altitudes from 6.0 km to 16.0 km
is at or below 0°C.
