what is atmospheric pressure?

Question

distinguish between areas of high and low atmospheric pressure

Answer 1

Atmospheric pressure is the pressure at any point in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.

Answer 2

Atmospheric pressure is the weight exerted by the air above any given location.
When large areas of the upper atmosphere warm up, the air expands and becomes less dense so it doesn't weigh as much creating an area of relatively lower surface pressure. Colder denser air creates areas of relatively higher pressure. The air pressure is measured at by barometers at weather stations all across the globe to determine where the areas of high and low pressure are centered, weather maps show the areas of equal pressure with isobars and the pressure areas are pretty much self descriptive, highs and lows.

Answer 3

the answerera above me are excellent in explaining to you about atmospheric pressure. I would also like to share with you the dangers of it. if you do not have the right equipment when going to high into the atmosphere you expand and eventually explode. if you go to deep for example deep in the ocean, without the right equipment the pressure will crush you from all sides approximatly 200 ft.. that also has a lot to do with the weight of the water. ever wonder why when you go to the bottom of the deep end swimming pool and your ears pop or even hurt, that is because of the pressure. hypothetical say in the pacific was just a hole and no water, if you were to go to the bottom the atmospheric pressure will still kill you. you wouldn't be able to breath.

Answer 4

Hi, atmospheric pressure is the downward force our atmosphere puts on us. These are the layers of Earths atmosphere: Troposhere, stratosphere, mesosphere, Thermosphere, lonosphere and exosphere.

Areas with high pressure have more pressure above their location and areas with low pressure have less pressure above their location. As evlevation increases atmospheric pressure decreases.

Answer 5

normal pressure at sea level is one atmosphere ( i think it's like 14. something pounds per square inch.) As you go higher in elevation the pressure lessons, as you go lower it increases. Cold and heat can also cause fluctuations of the pressure. High pressure usually equals warmer and low pressure equals colder. Thus, if it is very cold with low pressure in say UTAH, you could have a wind blowing towards there from say Idaho where it was warmer and had a higher pressure. Make sense?
