That is correct. If you think of the air as being a column of molecules, you can visualize that the mass of molecules in that column is forced downward by gravity. A 1cm square column extending upward to the top of the atmosphere weighs approximately 2.2 pounds. At an altitude further up the column where fewer molecules comprise a lesser mass they would exert proportionately less force. Another way to measure the weight of this column of air is by the pressure it exerts at a given point.
Temperature also has an effect on the pressure of air due to a change in the density of the air mass, thus two columns of air at at the same altitude might have different pressures because their temperatures are different. Generally, cold air has a higher pressure than warm air at the same altitude.
The decrease in pressure as altitude increases is called the pressure lapse rate, and has been tabulated for a "standard atmosphere" (one where the pressure and temperature at sea level are 29.92 in Hg (inches of Mercury) and 15 deg C respectively). Obviously, this varies in real world conditions but is approximately 1 in Hg per 1000 ft. The term lapse rate also applies to temperature changes with altitude and is approximately 2 deg C per 1000 ft on average depending upon the the moisture content of the air.
What else can I help you with?
As altitude increases in the Troposphere does the temperature increase?
No, as altitude increases in the Troposphere, the temperature generally decreases. This is because the Troposphere is the layer of the Earth's atmosphere where weather occurs, and the temperature decreases with altitude due to the decrease in air pressure and thinning of the air molecules that can store heat.
What happens to atmospheric pressure as altitude increase?
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.
What does the temperature do as you increase in altitude?
Temperature decreases as altitude increases because there are less molecules in the atmosphere to hold in the heat.
How does the temperature of the troposphere change as altitude increases?
In the troposphere, temperature generally decreases as altitude increases. This is due to the decreasing air pressure and the fact that the upper regions of the troposphere are cooler due to their distance from the Earth's surface.
How does the boiling temperature of water change with altitude?
Depending on the altitude the boiling point will differ. This calculator will give you the boiling point of the altitude that you desire to discover: http://www.csgnetwork.com/h2oboilcalc.html

What happens to air pressure when the altitude goes up?
When the altitude increases, the air pressure decreases (or "GOES DOWN") and vice versa. This is due to the fact that air is affected by gravity, therefore there is more of it at a lower altitude than at a higher altitude.
What does the temperature do as you increase in altitude?
Temperature decreases as altitude increases because there are less molecules in the atmosphere to hold in the heat.
How does the temperature of the troposphere change as altitude increases?
In the troposphere, temperature generally decreases as altitude increases. This is due to the decreasing air pressure and the fact that the upper regions of the troposphere are cooler due to their distance from the Earth's surface.
Do you get denser when you gain altitude?
No, you do not get denser when you gain altitude. In fact, air density decreases as altitude increases due to reduced pressure and gravity. This is why it can be harder to breathe at higher altitudes.
How does water pressure change with temperature variations?
As temperature increases, water pressure also increases. Conversely, as temperature decreases, water pressure decreases. This relationship is due to the fact that water expands when heated and contracts when cooled, affecting the pressure it exerts within a closed system.
What is the relationship between propane tank pressure and temperature?
The relationship between propane tank pressure and temperature is direct. As temperature increases, the pressure inside the tank also increases. Conversely, as temperature decreases, the pressure inside the tank decreases. This is due to the fact that propane is a gas and its molecules move more rapidly at higher temperatures, exerting more pressure on the walls of the tank.

Where is air pressure the greatest in the atmosphere?
Air pressure is the amount of force exerted on an object by the atmosphere. It is greatest at sea level.It is greatest in the exosphere, due to the fact that air pressure is greater as the altitude rises; the exosphere is the highest level within the atmosphere.Air pressure is greatest in the areas that are small and enclosed. This is because there is no way to escape.
What does Boyle's law say about the relationship between pressure and volume of gas?
Boyle's law describes the fact that, at constant temperature, the pressure and volume of a particular sample of gas are inversely proportional. As one quantity increases, the other decreases, and vica versa.
Is negative correlation bad?
No, the "negative" simply refers to the fact that one variable increases as the other decreases.
