WebMay 9, 2016 · By Roland Pease. New evidence from ancient volcanic rock suggests Earth’s atmosphere 2.7 billion years ago was less than half as thick as it is today. NASA. Air pressure is crucial for life. Not only does it help the atmosphere retain water vapor and trap heat from the sun, but it also affects the very chemical reactions on which life depends. WebThe atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention ( greenhouse effect ), allowing life and liquid water to exist on the Earth's surface, and reduces temperature extremes between day and night (the diurnal temperature variation ).
WebJun 28, 2016 · Typically, the weather of the earth is caused by processes that occur within the lowest 20 km of the atmosphere. This includes such phenomena as fog, wind, rain, storms, snow, tornadoes, and clouds. Air and consequently, our atmosphere, do have weight. This weight decreases as you go up within the atmosphere. WebDec 8, 2024 · The pressure of an atmosphere on a horizontal surface represents the total mass of a column of atmosphere from that surface all the way up into space. Of course atmospheric pressure works in all directions; considering only the vertical force allows us to understand how that pressure arises.
