Define Air Pressure

• The weight of a column of air pushing down on an area

• The Amount of Mass in a given volume

• The force pushing on an area

• The distance above sea level

_________________ increases as the density of air increases.

• Air mass

• Air pollution

• Atmospheric pressure

• Precipitation

Define air pressure

• Air pressure is the force exerted on a surface by the weight of the air above it.

• Air pressure is the force exerted by the weight of the ground on a surface

• Air pressure is the force exerted by the weight of water on a surface

• Air pressure is the force exerted by the wind on a surface

Warm air is ____________ than cold air so it ______________ and forms _____________________.

• less dense; rises; high pressure

• more dense; rises; low pressure

• less dense; rises, low pressure regions

• more dense; sinks; high pressure

• less dense; sinks; low pressure
