The water vapour in air is due to:a)The sweat of the animals evaporate...
Explanation:
The water vapor in the air is primarily due to the processes of evaporation and transpiration. Here is a detailed explanation of each source of water vapor:
Evaporation from Oceans, Rivers, Lakes, and Streams:
- Water bodies such as oceans, rivers, lakes, and streams contain large amounts of water.
- Due to the heat from the sun, the water molecules gain energy and turn into water vapor.
- This process is known as evaporation, and it is a major source of water vapor in the air.
Transpiration from Plants:
- Plants have tiny openings called stomata on their leaves.
- Through these stomata, plants release water vapor into the air.
- This process is known as transpiration and is an essential part of a plant's life cycle.
- Transpiration accounts for a significant amount of water vapor in the atmosphere.
Sweat Evaporation:
- Animals, including humans, produce sweat as a way to cool down their bodies.
- When sweat evaporates from the skin's surface, it turns into water vapor.
- This adds a small amount of water vapor to the air.
Conclusion:
In conclusion, the water vapor in the air is due to the combined effects of evaporation from water bodies, transpiration from plants, and sweat evaporation from animals. Therefore, the correct answer is option D - All of the above.
