Air Pressure
This is the force of air pushing down on Earth.
What is air pressure?
This word means how high you are above Earth's surface.
What is altitude?
The main source of energy for Earth's atmosphere.
What is the sun?
Earth heats unevenly because different surfaces _________ heat differently?
What is absorb?
Warm air is more or less dense?
What is less dense?
Air pressure is higher when there are _______ particles above you.
What is more?
At higher altitudes, the air is more or less dense?
What is less dense?
This type of heat transfer happens when warm air rises?
Land heats up faster or slower than water.
What is faster?
Cool air rises or sinks?
What is sinks?
This happens to air pressure as you go higher in altitude.
What is decreases.
This is why it is harder to breathe on a mountain.
What is less oxygen/fewer air particles?
An example of this type of heat transfer is the suns rays traveling to Earth.
What is radiation?
What is water heats and cools slowly?
This movement of air is caused by differences in air pressure.
What is wind?
This type of air (warm or cool) creates higher pressure.
What is cool air?
At sea level, air pressure is higher or lower?
What is higher?
When particles bump into each other to transfer heat?
What is conduction?
This causes differences in air temperature across Earth.
What is uneven heating from the Sun?
This is why the warm air broke up with the cool air?
What is because it needed some space ... things were getting too heated?
This happens to air pressure AND air density as warm air rises.
What is both decrease?
Air pressure is lower at high altitudes, so there are fewer air particles and less oxygen available to breathe.
Name all three types of heat transfer and an example of each.
conduction, convection, radiation
Explain how uneven heating of Earth leads to differences in air pressure.
