Is moisture the same as water?

Moisture refers to the amount of water vapor that is in the air. Since moisture is the presence of a liquid and often made up of small traces of water, it is safe to presume that moisture is the same as water in a sense.

Does High Humidity Mean More Moisture?

Because humidity is made up of water vapor, the higher the humidity, the more moisture that is in the air.  Once the humidity level reaches 100%, clouds are no longer able to hold anymore, which is what causes it to rain.
