There is measurable atmospheric pressure at the earth's surface. The pressure must be coming from something. Air offers resistance to movement independent of the effects of acceleration. It also supplies thrust and lift to aircraft; the movement of aircraft would be hard to explain without air.
Need to know what your question is.
When air pressure rises, it typically indicates the presence of high-pressure systems, which are associated with clear skies and stable weather conditions. As air descends in high-pressure areas, it warms and dries, leading to less cloud formation and lower chances of precipitation. Consequently, residents can expect sunny and calm weather when air pressure rises.

i think i know from my science teacher... Since Liquid, and solids sometimes
as far as i know, the 2000 sport does not have one--at least mine doesn't!!
Pneumothorax-presence of air or gas in the pleural cavity.
air bladder is present which regulates buoyancy
Air is matter because it has mass and takes up space. You can demonstrate this by observing how air interacts with its environment, such as when it fills a balloon or moves leaves on a tree. Additionally, air can be influenced by forces like gravity and pressure, further confirming its physical presence as matter.
A Bunsen burner can heat a solid in the presence of air by producing a hot flame that can be directed onto the solid material for heating purposes.
Increasing air pressure usually indicates the presence of descending air, which is associated with fair weather conditions. Conversely, decreasing air pressure typically indicates the presence of rising air, which can lead to the formation of clouds and potentially precipitation.
Cloud formation requires two main conditions: saturated air, meaning the air is holding as much water vapor as it can at a given temperature, and the presence of condensation nuclei, which are tiny particles that water vapor can condense onto to form droplets or ice crystals.
When a piece of copper is heated in the presence of air, it can react with oxygen to form copper oxide. This can result in an increase in weight due to the addition of oxygen atoms from the air to the copper atoms.
The presence of air in pipes can reduce the efficiency of a plumbing system by causing air pockets that block the flow of water, leading to reduced water pressure and potential clogs.
Pneumocrania is Pneumocephalus ... The presence of air in the intracranial cavity.
Heating an orc to a high temperature in the presence of air is a long process. It is when heat is transfer through atoms or molecules that move.
Carbon dioxide (CO2) and nitrogen oxides (NOx) are emitted when fuel is burned at a high temperature in the presence of air. These emissions contribute to global warming and air pollution.
Iron is the industrially important element that contains 26 electrons and rusts in the presence of air and moisture.
