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.
Does a parcel of air that rises undergo isothermal expansion?
It expands as a result of the decrease in pressure. In that respect it's isothermal, but it's also cooling for the same reason.
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 the air as you go up in elevation?
maybe its when the air of the atmosphere gets thiner and thiner.
An ecosystem has experienced a recent decrease in its plant populations. which ofthe following is a possible reason for the decline?
A decrease in the availiable water
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.
How high can the altitude be before you burn in the heat of the earths atmostsphere?
Altitude alone does not determine the heat experienced in the Earth's atmosphere. While temperatures generally decrease with higher altitudes in the troposphere, other factors like direct exposure to sunlight and weather conditions can impact how hot it feels. The atmosphere also contains different layers where temperatures can vary significantly.
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.
Is it true that atmospheric pressure decreases with increased altitude?
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.
Why does a helium-filled balloon rise to a certain altitude in the atmosphere and float there instead of rising further?
the reason is that as the balloon gradually goes up the density of air in the upper atmosphere decreases
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.

What is dry ice what will happen when the pressure is released on dry ice?
solid carbon dioxide (CO2) is stored under high pressure. Solid CO2 gets converted directly to gaseous state on decrease of pressure to 1 atmosphere without coming into liquid state. This is the reason that solid carbon dioxide is also known as dry ice
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 atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
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 does air pressure change with altitude. Why?
For the most part, it decreases. How technical do I need to be? There is less volume? The gravitional pull of the Earth isn't as strong? Do I need to take into account temperature? Wind speed? Is it a controlled enviornment? Because vaccumes suck?
