Atmospheric pressure is a unit of measument, and measure the pressure of the air. Much like the deeper you go in the ocean the higher the pressure is. You are actually on the bottom of an ocean of air, the higher up the less atmospheric pressure and eventually there is non when you reach outer space.

∙ 12y agoWhen the wind speed increases, the air pressure decreases.
[mec3usa] the above statement is true if the wind is blowing across the surface. One example of this situation is the wind flowing across the wings of a flying airplane.
However, when the wind is blowing at an object, the opposite is true. Pressure is proportional to the square of the wind speed. One example will be you standing in front of an electric fan with three speeds. You can feel greater force applied on your body when the speed is set at high than when it is low. Pressure = force / area. The larger the force, the higher the pressure on the same surface area.

How much air pressure equals 120 psi of water?
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
What is an offshore breeze?
Wind is caused by differences in air pressure. An offshore breeze is the result of high pressure over land, and low pressure over the water. The high pressure air moves toward the lower pressure air. Or...if you just had this question on a test in the Ebus workbook, then the correct answer is B) Land mass has cooled down.
What air movement of air that causes the winds?
The movement revolves around the Low Pressure System. At the center of a Low, air rises. That air descends in High Pressure Systems, that exist wherever Lows do not. This means that the Low Pressure System is the active feature of the [lower 10 km's of the] Atmosphere.
What happens when air is humid?
Humidity (relative) is the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature; the ratio of the actual water vapor pressure to the saturation vapor pressure. So pretty much the air is moist and heavy.
What happens to air pressure when water vapor increases?
Atmospheric pressure is reduced with increasing water vapor because the water has a lower molecular weight than dry air. The same number of molecules occupy a given volume at a given pressure, so the total mass of water vapor laden air is lower than dry air. If you add up the weight of a column of the wet air it will weigh less than the same column filled with dry air, hence, wet air has a lower air pressure.
What are some similarities between traveling through air and traveling through water?
Both air pressure and water pressure are measured in pounds per square inch. {Or some similar label in different parts of the world.}
Why does water have to do with air pressure?
In a well system, water is propelled by air pressure.
How a pressure difference is responsible for the movement of air?
The pressure pushes it around depending on how high or low the air pressure is.ANSWERAir moves from areas of higher pressure to areas of lower pressure. If you have a water balloon and you squeeze it, the area where your fingers are is similar to a high pressure zone. The water then flows away from your fingers to the lower pressure areas of the balloon. That is how air flows in the atmosphere. Things such as humidity and temperature differences cause the different pressure zones, and the air flows from high pressure areas to lower pressure ones.
Why is water pressure stronger than air pressure?
Think of it this way, if you had a plastic bottle filled with water and you poked a hole in the side, would water squirt out or would air squirt in? If air squirted in, then the air pressure would have to be higher. But since we know that the water would squirt out, we know that the water's pressure must be stronger. Of course, this is under normal conditions. If you pumped the air pressure up enough, then the air pressure may become stronger than standard water pressure. So actually, water pressure is generally stronger than air pressure.
Does deep sea have high air pressure or high water pressure?
High water pressure.
What is similar about the air pressure in a hurricane and a tornado?
Both produce intense low pressure.
Why is atmospheric pressure and water pressure different?
The big reason is because air is air, and water is water. The second reason is because air is compressible, while water cannot be compressed. What that means is that if you compress air to twice the pressure, it will be one-half the volume. If you compress water to be twice the pressure, the volume won't change.
Air pressure becomes lowet as water molecules are addrd to the air because water molecules?
Air pressure becomes lower as water molecules are added to the air because water molecules have less weight.
How is the modern flush toilet similar to the three hole experiment?
It is similar because they are both to do with water pressure - when you take the tape off the first hole, no water comes out because there is no air in the bottle. But there is when the second hole is released.
How does air pressure changes altitude increases?
It decreases. Air pressure is simply the pressure of all the other air on top of it. As you increase in elevation, there is less air on top of you. Therefore, the air pressure is less. As your altitude decreases, there is more air on top of you, therefore, the air pressure increases. Same with water. As you descend, water pressure increases. More on top of you.
How does water get into an air pressure tank?
If you mean a well tank, the water is forced in by the pump. The residual air pressure pushes the water out to the faucets.
What is a example of air pressure?
an example of air pressure would be 45% of water vapor outside.
