Yes.
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
False. The air pressure decreases and gets thinner as you go up. That is part of the reason why you can get nose bleeds as you go higher.
Yes air is denser near the earth's surface than high in the atmosphere. The farther up air rises, there are less molecules of air between the outer edges of the atmosphere. This means there is a lot less air weighing down. A general rule of thumb is the higher the altitude, the lower the pressure: the lower the altitude, the higher the pressure.
Its the hydrosphere
The air pressure is lower the higher the altitude. That is basically how an altimeter works.
yes
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
air grows thinner so it gives less pressure on the earth's surface
Inversely with altitude, the higher up you go the less air pressure
makes 40% oxygen than lower altitude
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.
Air pressure is the amount of pressure exerted by Earth's atmosphere in a specific place, while altitude is the vertical distance of an object or place from sea level. Air pressure decreases as altitude increases, since there is less atmosphere to exert pressure.
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
decrease as if you go deep into the earth the pressure increases If you blow a balloon up at sea level, and take it up to the top of the largest mountain, if the balloon hasn't pop, it would be bigger there than at sea level, because there is less air pressure as you increase your altitude, so the air within the balloon was "compacted" more or less at sea level and brought to a altitude where air was thinner and the air within the balloon would expand to try to compensate for the difference in pressure.
air grows thinner so it gives less pressure on the earth's surface
As altitude increases, air pressure decreases. As altitude decreases, air pressure increases.
