Question
What are the factors responsible for the variation air pressure of a region?
Answer
There are several factors that can cause variations in air pressure of a region, including:
- Altitude: As we move higher up in the atmosphere, the air pressure decreases because the weight of the air above becomes less.
- Temperature: When air is heated, it expands and becomes lighter, resulting in lower air pressure. Conversely, when air is cooled, it contracts and becomes denser, resulting in higher air pressure.
- Humidity: Water vapor is lighter than dry air, which means that an increase in humidity can result in a decrease in air pressure. This is because the water vapor takes up space that would otherwise be occupied by dry air.
