When air pressure changes, it can affect the weather by causing winds to move from high pressure areas to low pressure areas, leading to changes in temperature and moisture. Changes in air pressure can also affect our ears, such as feeling the pressure difference when flying in an airplane or diving underwater.

Why did your ears pop during a tornado?
During a tornado, changes in air pressure can cause your ears to "pop." This happens as your Eustachian tubes try to equalize the pressure inside your ears with the changing external pressure.
What are 2 main reasons air pressure changes?
Air pressure changes mainly due to changes in elevation and changes in weather patterns such as the movement of high and low-pressure systems. As elevation increases, air pressure decreases because there is less air above exerting pressure. Changes in weather patterns can lead to alterations in air temperature and density, affecting air pressure.
What happens to air pressure when the barometer is rising?
The air pressure is rising.
What instrument measures air pressure decreases during a storm?
Barometers measure air pressure.
What causes pressure changes in the atmosphere?
Pressure changes in the atmosphere are primarily caused by the movement of air masses. When warm air rises and cooler air sinks, it creates areas of high and low pressure. Other factors like altitude, temperature changes, and weather systems can also influence atmospheric pressure variations.
What does air pressure changes with changes?
air mass
What happens to an aneroid barometer when air pressure changes?
When air pressure increases, the metal aneroid capsule in the barometer contracts, causing the needle to move towards high pressure. Conversely, when air pressure decreases, the metal capsule expands, causing the needle to move towards low pressure. This movement of the needle indicates changes in atmospheric pressure.

What is the changes in air pressure caused by?
The changes are caused by the weight of air above it.
How does air pressure changes in tornado?
The air pressure drops sharply in a tornado
What happens to air pressure when the barometer is rising?
The air pressure is rising.
What happens to an aneriod barometer when air pressure changes?
When air pressure increases, the aneroid barometer contracts, causing the needle to move clockwise or indicate a higher pressure reading. Conversely, when air pressure decreases, the aneroid barometer expands, causing the needle to move counterclockwise or indicate a lower pressure reading.
What is the tool that records air pressure changes?
Barometer is the instrument that measures air pressure
What happens with air pressure when the air is cold?
The air pressure is high when the air is cold, and it's sinking.
What happens to air pressure when you move from the troposphere to the stratosphere?
air pressure decreases
What provides the ultimate driving source for wind?
changes in air pressure cause wind, but the sun is the major factor in changes to air pressure.
