Name three things that effect air pressure?

temperature, water vapor, and elevation.


Does vapor water contribute to global increase in temperature?

Yes, vapor water does contribute to the global increase in temperature. Water vapor is a greenhouse gas, meaning it can trap heat in the Earth's atmosphere. As the Earth's temperature rises, more water evaporates and enters the atmosphere, creating a positive feedback loop that amplifies the warming effect.


What gas is the most important?

This depends on what you mean by important. For instance chlorinated fluorocarbons at a given concentration have an effect thousands of times that of the same concentration of Carbon dioxide. Fortunately their concentration is very low. On the other hand water vapor has a lower effect than an equivalent amount of carbon dioxide but its concentration is very high (not surprising since two thirds of the earth's surface is water) so with the current composition of the earth's atmosphere water vaporhas the greatest effect. However the concentration of water vapor varies with the temperature and is not directly affected by human activities. If we were to increase the level of water vapor in the atmosphere and leave everything else unchanged, the water vapor would fairly quickly condense out as rain, snow, frost or dew and there would be no lasting effect on global temperaturesCarbon dioxide comes second after water vapor and its concentration in the atmosphere is heavily affected by burning of fossil fuels. As the CO2 concentration increases, the temperature of the atmosphere increases, as does its ability to hold water vapor. So an increase in CO2 results in an increase in water vapor and a further increase in temperature. Because CO2 does not condense out it has a lasting effect which is amplified by the ensuing increase in water vapor.


How does temperature affect amount of vapor in the air?

The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.


Carbon dioxide and water vapor act like a blanket over the earth?

greenhouse effect


How does temperature affects the amount of water vapor in the air?

The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.


What will happen to the water vapor in the air if the temperature drops as predicted?

When the temperature drops the less water vapor in the air


What will happened to the water vapor in the air if the temperature drops as predicted?

When the temperature drops the less water vapor in the air


What increases as water vapor increases?

Scientists studying the Earth's climate changes have found that increased temperatures lead to increases in water vapor in the atmosphere, which adds to global warming. This means that increases in temperature and water vapor feed each other.


How did condensed water vapor form the oceans?

It condensed water vapor to form the oceans by the Earth's vapor into the water.


Relative humidity changes with?

Addition of water vapor into the air, removal of water vapor in the air, decreases in temperature, and increases in temperature.


What do you call the temperature at which water vapor occurs because of cooling?

I believe you mean the temperature at which water vapor condenses due to cooling. This is the dew point temperature.
