Air (atmosphere) goes up to only a few miles from the surface of the earth. Imagine a column of air as felt on the surface of the earth. Every square unit of area experiences the force exerted by this enormous column of air. As you travel upwards the column of air above from that point up is smaller and so exerts less force per unit area. Force per unit area is pressure and that is why the pressure decreases as we travel up.
To give you something you can relate to easily, the pressure at the bottom of a swimming pool will be more than the pressure half way up from the bottom because in the first case a larger column of water exerts its weight whereas in the second case it exerts only half the weight.
What else can I help you with?
How does air pressure change as altitude change?
Increased altitude means decreased air pressure.
How does altitude affect phase change?
The change in pressure is highly affected by altitude.
Does air pressure change as altitude increases?
Yes, air pressure decreases as altitude increases.
How does barometric pressure change with altitude?
Because pressure decreases as you go up in altitude and increases when you go down in altitude. Hope this helped!
What happens to air pressure's rate of change as altitude increases?
As altitude increases, the rate of change of air pressure decreases. This is because the air becomes less dense at higher altitudes, leading to a more gradual decrease in pressure with increasing altitude.
How does air pressure change in the atmosphere as the altitude change?
By farting
What could cause a change in air pressure?
Altitude
Can air pressure falls drastically at high altitude?
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
What happens to pressure as altitude increased?
As altitude increases (i.e. when you get higher) pressure falls off inversely; a change near the higher reaches will not have as much of a pressure differential as the same distance change lower down.
Does melting point change from altitude to altitude?
Yes, the melting point of a substance can change with altitude due to the variation in atmospheric pressure. As altitude increases, atmospheric pressure decreases, which can affect the boiling and melting points of substances. Generally, lower pressure at higher altitudes can result in lower melting points for many substances.
Does air pressure change with altitude?
The higher up you are the lesser the air pressure in the atmosphere.
How does pressure change as you increase in altitude within your atmosphere?
it decreases
