ATMOSPHERIC PRESSURES Meaning and
Definition
-
Atmospheric pressure refers to the force exerted by the Earth's atmosphere per unit area at a given point. It is commonly defined as the weight of the air above a particular location. The atmosphere is composed of a mixture of gases, predominantly nitrogen and oxygen, which exert pressure due to their combined weight.
Atmospheric pressure varies with altitude and is higher near the surface of the Earth, gradually decreasing as one moves upward. This decrease in pressure is due to the diminishing amount of air molecules present at higher altitudes. By convention, atmospheric pressure at sea level is designated as 1 atmosphere, which is equivalent to approximately 101.3 kilopascals or 14.7 pounds per square inch. However, atmospheric pressure can also be expressed using different units such as millibars or inches of mercury.
Atmospheric pressure plays a crucial role in various natural phenomena. It influences weather patterns, as areas of high pressure are generally associated with fair weather, whereas areas of low pressure often indicate stormy conditions. Atmospheric pressure also affects the boiling and freezing points of liquids, making it significant in processes such as cooking and the functioning of barometers. Additionally, it impacts human physiology, especially at high altitudes, where lower atmospheric pressure can lead to altitude sickness due to decreased oxygen availability.
In summary, atmospheric pressure is the force exerted by the Earth's atmosphere on a surface and is essential in understanding weather patterns, physical processes, and the effects of altitude on human beings.

Etymology of ATMOSPHERIC PRESSURES
The word "atmospheric" originated from the Greek word "atmos", meaning "vapor" or "vaporous exhalation". It was later adopted in Latin as "atmosphaera", which refers to the "sphere of vapor". The word "pressure" stems from the Latin word "pressura", meaning "a pressing" or "compression".
Combining these two terms, "atmospheric pressures" refers to the forces exerted by the atmosphere due to the weight of the air above.
