The state of atmosphere in relation to its water vapour content refers to:

A. Relative Humidity

B. Relative Density

C. Precipitation

D. Frontal Humidity

Answer: Option A

Solution(By Examveda Team)

Relative Humidity is the amount of water vapour present in air. Water vapour, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. The amount of water vapour needed to achieve saturation increases as the temperature increases.
