are these correct?
Since this is not my area of expertise, I searched Google under the key words "humidity and temperature" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
This might be additional help.

Yes, the answers you provided are correct.
4. The primary control of how much water vapor the air can hold is the temperature of the air. As the temperature increases, the air can hold more water vapor, and as the temperature decreases, the air can hold less water vapor.
6. Cooling the air would cause the relative humidity to increase. When the air is cooled, its capacity to hold water vapor decreases, which can lead to an increase in the relative humidity. The relative humidity is the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature.
Yes, the answers provided are correct.
To explain how to arrive at these answers:
4. The primary control of how much water vapor the air can hold is determined by the temperature of the air. This relationship is known as the saturation vapor pressure, which describes the maximum amount of water vapor that can exist in the air at a given temperature. As the temperature increases, the air can hold more water vapor, and as the temperature decreases, the air can hold less water vapor.
6. Increasing relative humidity occurs when the air is cooled. Relative humidity is a measure of how saturated the air is with water vapor, expressed as a percentage. When the air is cooled, its ability to hold water vapor decreases, causing the relative humidity to increase. Cooling the air could occur due to a variety of factors, such as adiabatic cooling from uplift or cooling from contact with a colder surface.
It's important to note that the other options listed in both questions also have influences on atmospheric moisture, but they are not the primary controls or direct causes for the specific scenarios mentioned in the questions.
