Do cold air masses have higher or lower air pressure than warm masses?
KyleMarshall15
Yes. Cold air masses have higher density, because the molecules are closer together. That makes them have higher pressure because there is more mass per unit volume pressing down.
The molecules are closer together because they are colder, and, with less energy, which is the same as temperature, they vibrate less, so that causes them to move closer together.

∙ 12y agowarm air has more energy so it goes around a lot faster than cold air so warm air spreads out more so there is less warm air in an amount of space than there would be cold air and less air particles = less pressure.

Do currents of cold sinking air produce regions of higher pressure or lower pressure at the earths surface?
Sinking air would add air to the surface, raising the pressure.
When a warm air mass overtakes a cold air mass it form a?
Yes. Cold air masses have higher density, because the molecules are closer together. That makes them have higher pressure because there is more mass per unit volume pressing
What happens in cold and warm air masses?
what happens in cold and warm masses pressure
What is a cold air mass with high pressure called?
When two air masses collide, it is called a front.
Is barometric pressure connected to the temperature?
Barometric pressure has everything to do with temperature. There is a simple way to understand the relationship... The higher the temperature is, the lower the pressure. The lower the temperature is, the higher the pressure. Reasoning: Barometric pressure is caused by expansion and contraction of gaseous molecules(the air we breathe). Heat causes the molecules to expand, and become less dense, causing the warm air to rise, and pressure to be dropped. Cold causes the molecules to contract, making the air become more dense, and fall closer to the ground. Heat is rapidly moving, generously spaced molecules. Cold is slower moving, closer spaced molecules.
Do cold air masseshave higher or lower air pressurethan warm air masses?
higher
Does most cold air masses have higher air pressure than most warm air masses?
true
Why do balloons deflate in cold weather?
Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.
If you are on top of a mountain is the air pressure higher because of the cold temperature or lower because you are higher up?
lower because you are higher up
Why does a balloon deflate in cold air and expand in hot air?
Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.
Do currents of cold sinking air produce regions of higher pressure or lower pressure at the earths surface?
Sinking air would add air to the surface, raising the pressure.
When you are on top of a mountain is the air pressure higher dou to the cold temperature of lower due to the high altitude?
Higher than what? As you go up a mountain the air pressure gets lower simply because there is less air above you weighing down on you.
When a warm air mass overtakes a cold air mass it form a?
Yes. Cold air masses have higher density, because the molecules are closer together. That makes them have higher pressure because there is more mass per unit volume pressing
Pressure differences between warm and cold air masses cause what?
Pressure differences between warm and cold air masses cause fronts or high/low pressure systems. A warm front is when a warm, moist air mass slides up and over a cold air mass, and a cold front is the opposite.
What happens in cold and warm air masses?

Will temperature be higher or lower in a mountain?
it is lower temperature when you to mountain,because its cold there
