Differentiate between:
(a) Humidity and clouds
(b) Relative humidity and Absolute humidity
(c) Cumulus clouds and cumulonimbus clouds
Answers
"a. Humidity is the atmospheric phenomenon. It is the amount of water vapour present in the atmosphere whereas cloud is a visible mass of condensed water vapours which are floating in the sky.
b. Relative humidity is the humidity content of the atmosphere expressed as a percentage of the amount needed for saturation at the same temperature. Absolute humidity is also the amount of water vapour in the air. The basic difference stands that relative humidity takes in account the temperature but not absolute humidity.
c. Both the clouds are more or less the same but the basic point of difference is the vertical development of the Cumulus clouds which is not there in the latter.
"
a) Humidity is the amount of water vapour present in the air whereas clouds are the formation when the relative humidity has reached its 100%.
b) The water vapour present in the air irrespective of temperature is termed as absolute humidity whereas relative humidity is the amount of water vapour present in the air relative to the temperature.
c) Cumulus clouds are the clouds which are called fair weather clouds and are observed lower in the atmosphere whereas cumulonimbus clouds are those which are produced when there is too much vertical energy in the cumulus clouds. It is the cumulonimbus clouds which cause rain, thunderstorm and etc.
