Air has pressure due to the weight of the air molecules above it pushing down. The force of gravity pulls the air molecules towards the Earth's surface, causing them to compress and create pressure. Atmospheric pressure decreases with increasing altitude as there are fewer air molecules above.

What causes air preasure?

Air pressure is caused by the weight of air molecules pressing down on a surface due to gravity. The pressure decreases with increasing altitude as the column of air above decreases. Temperature, altitude, and weather patterns can also affect air pressure.


Why did Mount Tambora erupted?

it was the sea it made cracks in the volcano and made preasure causing it to erupt !!!


How does the sun influence winds on Earth?

The energy from the Sun does not influence the global winds, it causes them. Without the Sun's energy, there would be no atmospheric movement - your question implies something else causes the global winds and the Sun modifies these. This is not the case.


What does Barometric Pressure tell us?

Barometric pressure is a measurement of the weight of the air above us. It can help predict weather changes, as high pressure often indicates fair weather and low pressure can bring in storms or precipitation. Significant changes in barometric pressure can also affect our bodies, leading to headaches or joint pain in some individuals.


How do sciestests measure air preasure?

Scientists measure air pressure using instruments called barometers. There are two main types: mercury barometers, which use a column of mercury in a glass tube, and aneroid barometers, which use a sealed, flexible metal chamber that expands or contracts with changes in pressure. The height of the mercury column or the movement of the aneroid chamber is then calibrated to provide a measurement of air pressure, usually expressed in units like millibars or inches of mercury. These measurements are essential for weather forecasting and studying atmospheric conditions.

Air moves from a point at which air pressure is to a point at which air pressure is?

higher. This movement of air is driven by the pressure difference between the two points. The air flows from areas of higher pressure to areas of lower pressure in an attempt to equalize the pressure.

Air expands when heated so therefor increases the preasure


How do hovercrafts glide and fly... what makes them fly if the air is making it hover?

their are several forces at work but the main one is a cushion of high perasure air - the fan blades do not so much act as thrust as increasing the air preasure under the hovercraft - a rubber skirt surrounds the craft to keep the air in - if the hovercraft goes to high the air flows out and air preasure is lost and no more hovering - so hovercraft arent really flying so much as just sitting on a cushion of air - forward propulsion can come from a variety of engines but can be also produced by tilting the craft slightly allowing a bit of high preasure to escape from one side of the skirt
