7 The water vapor present in the air is due to
The correct option is D all the above
The explanation for the correct option:
(D)-All the above
(A) Evaporation of water occurs from rivers, oceans, steam, and lakes
At the air-sea interface, water molecules change phase from liquid to vapour, resulting in oceanic evaporation. The available heat energy, the difference in humidity between the air and the surface, and the wind speed all influence the rate at which this process happens.
(B) Water vapour is given out by plants through their leaves.
Transpiration is the loss of water from plants' leaves while their stomata are open to allow and to pass through during photosynthesis.
(C) Water vapour is given out by animals when their sweat evaporates
When sweat droplets evaporate from an animal's skin, they carry a small amount of the animal's body heat with them. They, like water evaporating from plant leaves, convert into water vapour and join the water cycle.
Final answer: The correct answer is an option (D)
