Science Air Pressure Review

What is air pressure?

• altitude

• wind

• Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.

• horizontal moving

What are the 3 factors of Air pressure.

• Altitude

• Heat

• Wet

• Humidity

What is a Barometer?

• A tool to measure air pressure

• a tool to measure Humidity

• a tool to measure height

• a tool to measure food

A falling barometer is followed by several days of rainy weather. Is the Air Pressure Increasing or decreasing and why?

• The barometer is falling after several days of rain because the air pressure is decreasing. It would decrease because their is less hydrogen in water,

• The barometer is falling after several days of rain because the air pressure is increasing. It would increase because their is more hydrogen in water.

Some people find it hard to breathe at high altitudes. Why is it hard to breath, and is the air pressure increasing or decreasing, and Why?

• It is harder to breathe at high altitudes because the air pressure is increasing. It would be increasing because the air get thinner and it is further away from the earth's gravitational pull.

• It is harder to breathe at high altitudes because the air pressure is decreasing. It would be decreasing because the air get thinner and it is further away from the earth's gravitational pull.

A rising barometer indicates a spell of cool, dry weather. Is the air pressure increasing or decreasing?

• A rising barometer indicates that dry weather is coming because there is an increase of more air pressure because the weather is cool and dry.

• A rising barometer indicates that dry weather is coming because there is an decrease of less air pressure because the weather is cool and dry.

A series of hot, humid days is preceded by a falling barometer. Is the air pressure increasing or decreasing?

• A series of hot days is coming because the air pressure is decreasing because the molecules are more spread apart.

• A series of hot days is coming because the air pressure is increasing because the molecules are more close.

A southern coastal area tends to have lower air pressure than an inland area farther north. Why does the north have higher air pressure?

• A southern coastal area tends to have lower air pressure than an inland area farther north because the north is a lot cooler than the south.

• A southern coastal area tends to have high air pressure than an inland area farther north because the north is a lot hotter than the south.

Rapidly dropping temperatures are accompanied by rising barometers. Would rapidly dropping temperatures have an increasing or decreasing amount of air pressure.

• Rapidly dropping temperatures would have an decreasing amount of air pressure because the temperature is hotter and the molecules are spread out from one another.

• Rapidly dropping temperatures would have an increasing amount of air pressure because the temperature is colder and the molecules are closer together.
