The two correct answers that can help determine air pressure are:
-
Temperature of the air - Changes in temperature can affect air pressure; warmer air is lighter and can lead to lower pressure, while cooler air is denser and can result in higher pressure.
-
Moisture in the air - Humidity affects air pressure; moist air is less dense than dry air, which can influence pressure readings.
Wind speed and cloud patterns can be related to air pressure changes but are not direct measures of air pressure itself.
