To determine air pressure, the two correct answers from your list are:
-
Moisture in the air - Humidity can affect air pressure. More moisture in the air generally leads to lower air pressure.
-
Temperature of the air - Warm air is less dense and tends to rise, which can lead to lower air pressure, while cooler air is denser and can result in higher air pressure.
Cloud patterns and wind speed are not direct indicators of air pressure but can be influenced by it.
