As altitude increases, the weight of the atmosphere above decreases, leading to lower pressure. Essentially, there are fewer air molecules at higher altitudes exerting pressure downward.

What happens to the air as you go up in elevation?

maybe its when the air of the atmosphere gets thiner and thiner.


Why is the air pressure lower at higher altitude?

Same reason water pressure is higher the deeper you go. There's more stuff above, pressing down. Air has density and weight too.


What happens to the temperature as you increase in altitude in each layer of the atmosphere?

The temperature in the atmosphere decreases as altitude increases. The reason for this is there is less warmth from the surface of the earth reaching the higher altitudes because there are fewer particles of the atmosphere to transfer the heat. The temperature begins to increase, however, around 100km in altitude because of the heat and radiation from the sun.


What happens to pressure as you move outward from earths interior?

Pressure decreases as you move outward from Earth's interior. This decrease is due to the weight of the rock layers above exerting less force as you move towards the surface. The pressure gradient is part of the reason why we have different layers within the Earth.


Can you use P1V1 P2V2 to find the volume of a weather balloon at a certain altitude?

Yes, you can use the combined gas law formula P1V1 = P2V2 to calculate the volume of a weather balloon at a certain altitude. This formula relates the initial pressure and volume of the balloon to the pressure and volume at a different altitude, given that the temperature remains constant. By manipulating the formula, you can solve for the unknown volume at the new altitude.

Why does atmospheric pressure start to decrease around midnight when with the temperature decrease pressure should increase?

The reason for temperature being lower in high altitude regions (as compared to places at sea-level) is due to the decrease in atmospheric pressure as we go up in altitude. So decrease in atmospheric pressure causes the temperature to decrease, which might be a reason for the decreased pressure at night. --- Diurnal temperature fluctuations vary by location, but follow a twice-daily cycle of general rise and fall, corresponding to the "atmospheric tide" induced by the eastward rotation of the planet.


Why does a helium-filled balloon rise to a certain altitude in the atmosphere and float there instead of rising further?

The helium-filled balloon rises to a certain altitude in the atmosphere and floats because at that point, the buoyancy force (upward force) of the helium inside the balloon equals the gravitational force pulling the balloon downward, resulting in equilibrium. This balance of forces causes the balloon to stay at a stable altitude instead of rising further. Additionally, the surrounding air pressure and density decrease with altitude, affecting the balloon's ability to rise further.


Is it true that atmospheric pressure decreases with increased altitude?

Yes, it is true that atmospheric pressure decreases with increased altitude. This is because there is less air above pushing down on the air below as you go higher in the atmosphere. This is why it becomes harder to breathe at high altitudes due to the lower pressure.


How high can the altitude be before you burn in the heat of the earths atmostsphere?

When the altitude on Earth increases, the temperature decreases. The reason spacecraft are incredibly hot upon re-entry into the Earth's atmosphere is due to the friction of the molecules in the atmosphere on the spacecraft, which are traveling at extremely high speeds.


How do you use the Mitsubishi Pajero altimeter gauge?

An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. The altimeter uses the changes in atmospheric pressure to determine the changes in altitude. Why does pressure change with altitude? Simply put, the pressure at any given point in the atmosphere around the earth is a result of the weight of the atmosphere above it (pulled down by gravity). For this reason, the higher in the atmosphere you are, the less atmosphere you have above, and the less pressure exerted on you. Measuring altitude with barometric pressure is not free from difficulties, however. Atmospheric pressure can also change with changes in weather patterns. On an uneventful weather day it is not too unusual for an air pressure change of 1 mbar, caused by temperature changes alone. This 1 mbar change in pressure could result in a skewed altitude reading of up to 26 feet (8 meters). But on an afternoon full of weather changes, like an approaching cold front, air pressure could change by as much as 5 mbar, or more. This could result in a skewed altitude reading of up to 130 feet (40 meters), or more. Typically, when bad weather is approaching, the pressure will be falling. And the altimeter thinks this decrease in pressure is due to an increase in altitude, so it will read higher than you really are. And the opposite is the case when the weather conditions are improving - the altimeter will read lower than you really are. In order to compensate for weather changes, an altimeter must be calibrated using a known altitude or a known pressure value. A known altitude can typically be taken from a specific landmark on a topographic map. But if you do not have a known altitude to use, you will need to use a known pressure value. This is typically done with a barometric pressure value. "Barometric Pressure" is the current air pressure at sea level, for a specific location. Barometric pressure is measured several times per day, and can usually be obtained from flight service stations or aviation weather reports. With all of the changes that affect an altimeter, your elevation can easily be skewed by a few hundred feet in as little as one day's time. You will want to calibrate your unit at least once per day, but for improved accuracy (especially in changing weather conditions), you may want to calibrate it every couple of hours at a known elevation.


Does the atmosphere get colder the higher up you go?

Yes, the temperature generally decreases with increasing altitude in the atmosphere. This is due to the fact that the atmosphere becomes less dense at higher altitudes, leading to a decrease in the amount of air molecules that can trap heat.


How the temperature changes as you travel up through the atmosphere.?

The temperature in the atmosphere decreases as altitude increases. The reason for this is there is less warmth from the surface of the earth reaching the higher altitudes because there are fewer particles of the atmosphere to transfer the heat. The temperature begins to increase, however, around 100km in altitude because of the heat and radiation from the sun.

Why doe the amount of water vapour decrease rapidly with altitude?

To know the reason behind it remember one thing that with increasing altitude the temperature decreases eg. in may month there will be high temperature in mumbai that is at low altitude and comparatively low temperature in himalayan region (eg. srinagar) that is at high altitude.Now as we know that high temperature increases the rate of evaporation and if the rate of evaporation is increased through leaves then more water will go into atmosphere and humidity will increase and this gives us our answer that is...............at high altitude because of low temperature the evaporation rate decreases and thus there are less water vapour in atmosphere as compared to low altitude areas where there is high temperature and high vapour rate in air due to evaporation


Why is the air pressure lower at higher altitude?

Same reason water pressure is higher the deeper you go. There's more stuff above, pressing down. Air has density and weight too.


How is air pressure related to altitude?

The higher you go, the lesser the air pressure becomes. This can be logically understood. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.
