The concentration of water vapour in troposphere, which depends upon the altitude & temperature varies in the range of zero to __________ percent.a)1b)4c)8d)12Correct answer is option 'B'. Can you explain this answer?

Question

Answer

The concentration of water vapor in the troposphere varies with altitude. Generally, the concentration decreases as altitude increases.

At lower altitudes, closer to the Earth's surface, the concentration of water vapor is higher. This is because the surface of the Earth is the main source of water vapor through evaporation from bodies of water, such as oceans, lakes, and rivers. Additionally, plants and trees release water vapor through transpiration.

As altitude increases, the air becomes cooler and the capacity for holding water vapor decreases. This leads to condensation and the formation of clouds. Therefore, at higher altitudes, the concentration of water vapor decreases due to condensation and cloud formation.

However, it's important to note that the actual concentration of water vapor in the troposphere can also vary due to various factors such as temperature, humidity, air currents, and weather patterns.
