Which of the following is true of atmospheric water vapor (choose all that apply)? a. releases large amounts of latent heat during cloud formation b. is a potent greenhouse gas c. its atmospheric concentration is constant in both space and time d. is invisible e. enters the atmosphere via precipitation and leaves the atmosphere via evaporation f. comprises up to 4% of the air's volume near earth's surface g. the most abundant permanent atmospheric constituent

Option (A), (B), (D), (E) and (F)

Explanation:

Water vapor is one of the most important green house gas in the earth's atmosphere. It is colorless and invisible, and a small increase in the amount of water vapor can cause significant changes in the atmosphere, thereby increasing the earth's global temperature. Water vapors when forms cloud, liberates significant quantity of latent heat, which initiates the formation of hurricanes and thunderstorms.

The water vapor circulates in the atmosphere as it falls on the ground surface in the form of rainfall and also is again released into the atmosphere by the evaporation process. Atmospheric water vapor contains a maximum of 4% of volume of air near to the surface of the earth.

Thus, the correct options supporting the characteristics of water vapor are given above.

Explanation:

b. 20: 5

explanation:

20% of the worlds population lives in southwest asia, and less than 5% of the world's

land area.
