False
|
|
The capacity of air to hold water vapor is temperature dependent.
|
True
|
|
Clear skies are associated with substdence or sinking motion.
|
True
|
|
Adiabatic temperature changes refer to parcels of air that rise or sink.
|
True

|
The circulation of water vapor through the atmosphere is very small compared to the Earth's rivers systems.

|
True
