During the daytime the sun warms the earth's surface, thus increasing the air temperature. What would happen to relative humidity as the sun warms the earth?Group of answer choicesIt would decrease.It would increase.It would stay the same.None of these.
Solution
Relative humidity would decrease as the sun warms the earth. Here's why:
-
During the day, the sun heats the earth's surface, which in turn warms the air above it.
-
As the air temperature increases, its capacity to hold water vapor also increases. This is because warmer air has more energy, allowing more water to evaporate and exist as a gas.
-
Relative humidity is the amount of moisture in the air compared to the maximum amount of moisture the air could hold at that temperature.
-
So, if the amount of moisture stays the same, but the air's capacity to hold moisture increases (due to the temperature increase), the relative humidity decreases.
Therefore, as the sun warms the earth, the relative humidity would decrease.
