ATMOSPHERIC LAYERS
What is the transfer of heat by the circulation of air due to density differences?
Convection
What type of pressure is found at the poles?
High pressure.
Cold Air sinks
What local breezes occur at night when the air over cooler land flows toward the warmer water?
Land breezes.
What are the two permanent (most common) gases in our atmosphere?
Nitrogen and oxygen
What is the layer in which we live, and where planes fly?
The troposphere
Why is low pressure found at the equator?
Because that is where warm air is found.
Warm air rises.
What type of pressure is found over the water during the day time and why? (sea breeze)
High pressure because the water is colder than land
What are the percentages of nitrogen and oxygen in our atmosphere?
78% nitrogen, 21% oxygen
What is the hottest layer where the auroras occur?
The thermosphere
What is the transfer of heat in waves but NOT direct contact?
Radiation
Daily Double: Give two reasons why Local winds are different from Global winds
1. Local winds cover small areas
2. They change Directions
What type of pressure is found over the water at night and why? (land breeze)
Low pressure because water is warmer.
What is the measure of the force with which air molecules push on something?
Air pressure
Which layer has the ionosphere and is below exosphere?
The thermosphere
Why does equator increase faster than the poles of the Earth?
The equator receives more direct sunlight than the poles.
What causes the Coriolis effect?
The rotation of the Earth.
What local breezes occur during the day because the air over the land heats up faster than the air over the water?
Sea breezes
Which layer is known to absorb the UV rays of the Sun?
Ozone Layer
Heat always moves from _________ to _________
From warm to cold.
Due to the angle of the sunlight hitting the Earth, unequal heating of the Earth's surface occurs. This unequal heating produces __________.
Winds
Chance Double: What does air pressure have to do with winds? Which way does the Wind Blow?
It causes them. Winds blow from high to low pressure.
PICTURE:
Which station has the most direct heat transfer?
Station A
