Does the atmospheric pressure increase or decrease as you move upward away from sea level?

Atmospheric pressure decreases as you move upward away from sea level due to the decrease in the weight of the air above pushing down. This means that atmospheric pressure is lower at high altitudes and higher at lower altitudes, such as at sea level.


Does pressure increase or decrease with altitude?

Because as you climb higher there is less air above you pressing down on you with its weight.


How would the reading of a barometer change as you decrease in altitude?

As you decrease in altitude, the reading of a barometer will increase. This is because atmospheric pressure is higher at lower elevations due to the greater weight of the air above. Consequently, a barometer measures this increased pressure, resulting in a higher reading as you descend.


When warmer air rises above the frontal surface expands and cools as it ascends does it relative humidity increase or decrease?

When warmer air rises above the frontal surface, it expands and cools as it ascends. As the air cools, its relative humidity increases because cooler air has a lower capacity to hold moisture, leading to saturation and potentially precipitation.


Above the bubble-point pressure the oil formation volume factor increase or decrease?

Above the bubble-point pressure, the oil formation volume factor decreases. This is due to the expansion of gas released from the oil as pressure decreases, causing the volume of oil to increase for a given mass.

Are above or over the same or different?

Different.because over is increase,above is decrease.


How do you find percent increase and decrease?

If you start with a value x and end with a value y thenPercentage change = 100*(y/x - 1)If y > x then the above is positive and is a percentage increase andif y < x then the above is negative and is a percentage decrease.


Does water volume increase when it is refrigerated?

If the water is above 4C in temperature ( above 40F) it will decrease in volume if refrigerated. When it reaches 40F then it will start to increase in volume, and when it freezes at 32F (0C) it increases a lot in volume when it becomes ice. After that, below 32C, it starts to decrease again.


In a pressure chamber filled with gas above a liquid solution a decrease in volume causes?

AN increase n pressure, an increase in gas concentration in the solution


Why does eRV decrease during exercise?

Inspiratory Reserve Volume is the excess volume above the tidal volume that can be inspired. During exercise, there is an increase in demand for oxygen which leads to a decrease in IRV.


Why the density of air decrease with the increase in height?

Because the higher you go, the less air there is above to push down and compress the air around you.


Does a base increase or decrease pH?

Anything above 7 is basic, anything below 7 is acidic. So a strong base will have a high pH.


Does temperature increase or decrease with altitude in the mesosphere?

Temperature decreases with altitude in the mesosphere due to the decrease in atmospheric pressure with height. This is because the mesosphere is above the stratosphere where the ozone layer absorbs incoming solar radiation, leading to a decrease in temperature as altitude increases.


Why is the percent increase from forty five to seventy five not equal to the percent decrease from Seventy five to forty five?

Because percentage changes increases or decreases - are calculated relative to the starting value, which appears as the denominator in the calculations. In the above example, the increase will be relative to 45 whereas the decrease will be relative to 75.


How does temperature affect the growth and yield of crops?

When annual temperatures increase sharply above the ideal crop temperature, it can cause a decrease in a crop's yield. Likewise, other factors like an increase in carbon dioxide levels can cause an increase in the growth of crops.


Does air pressure increase or decrease as you go higher?

Air pressure decreases as you go higher in the atmosphere. This is because there is less air above pushing down. As altitude increases, the air becomes less dense, resulting in lower pressure.


If you're traveling from Colorado to Mississippi is the elevation increasing or decreasing?

It would decrease markedly. Mississippi's highest point is only 806 feet above sea level. Colorado's lowest point is 3,315 feet above sea level and its average elevation is 6,800 feet above sea level.It would be all downhill.
