When warm air expands and rised it creates an area of what?
Low pressure
Describe the path of air as it travels into a low-pressure area in the northern hemisphere?
Winds in the Northern Hemisphere tend to blow clockwise out of areas of high pressure and counterclockwise into areas of low pressure.
When is a hot air balloon behaving like an air mass in a low pressure area?
g
What causes the drop of a wall cloud?
A wall cloud marks an area of low pressure within a mesocyclone. The pressure drop causes a temperature drop, which in turn causes water vapr to condense.
Do clouds form easily when the air pressure is high or low?
Clouds only form when the air pressure is low.
Are winds stronger near a high pressure area or a low pressure area?
low pressure
Do clouds rise in the center of a low pressure or high pressure area?
Air rises in a low pressure area and sinks in a high pressure area.
Area of low pressure where masses meet and rise?
Cyclones is the area of low pressure
Why is cool air an area of low pressure?
Cool air is an area of low pressure because temperature is directly proportional to pressure. So when the pressure is low, the air is cool (low temperature).
Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
Does vacuum refer to an area that has high or low pressure?
Low pressure
What moves from a high pressure area to a low pressure area?
Air.
What is a stationary front an area of high or low pressure?
A stationary front would be associated with an area of low pressure (high pressure does not have fronts).
What is produced from an area of high pressure to an area of low pressure?
Diffusion occurs when an area of high pressure meets an area of low pressure. They mix together and create an equilibrium, all particles spread out equally.
How are the air masses and fronts different?
Air mass - refers to any area of high or low pressure. A front - is the point at which an area of high pressure meets an area of low pressure.
Winds are generated when air flows from a high pressure area into a what?
low pressure area.
What is the name of air flowing from a high pressure area to a low pressure area?
Wind
