Answer :
On a rainy day, the air pressure tends to be lower than on a sunny day. This is because during rainy weather, the presence of low-pressure systems is more common. Low-pressure systems are associated with unsettled weather conditions like rain and storms.
On the other hand, high-pressure systems are more typical during sunny days. High-pressure systems bring about stable and clear weather conditions. Therefore, on a sunny day, the air pressure is generally higher compared to a rainy day.
In conclusion, the air pressure is typically lower on a day when it is raining compared to a sunny day when it is higher.
