Does the Equator get direct or indirect sunlight during the year?
Direct sunlight
100
What letter is Maritime represented with when showing air masses?
lowercase m (m)
100
What is the transfer of energy through electromagnetic waves?
Radiation
100
What is it called when the relative humidity is at 100%?
Saturated
100
What month is aphelion in?
July
200
What is it called when the Earth is at its furthest point from the Sun?
Aphelion
200
What letter represents Arctic when showing air masses on a map?
capital a (A)
200
What is the transfer of thermal energy through contact?
Conduction
200
What is the formula (water vapor in the air/total capacity) for?
Relative Humidity
200
What type of air mass can hold more water vapor, Tropical or Polar?
Tropical
300
What is insolation?
Exposure to the sun's rays
300
What conditions would a cT air mass bring?
Warm temperatures and low moisture
300
What is convection?
Convection is when the air circulates in the atmosphere
300
What is humidity?
A measure of the amount of water vapor in the air.
300
What color absorbs the most radiation?
Black
400
What shape does indirect sunlight make on the Earth?
What shape does direct sunlight make on the Earth?
Indirect- Oval
Direct- Circle
400
Where is a cP air mass's source region in North America?
Canada
400
Name two types of energy transfer.
Radiation and Conduction
400
What allows for the air to have a higher capacity for water vapor?
Warmer temperatures have higher capacities for water vapor.
400
What can be used to measure humidity?
A psychrometer
500
What is the angle of insolation and how does it affect different areas of the Earth?
The angle of insolation is the angle at which the sun's rays hit the Earth. If the angle of insolation is a right angle with the Earth's surface's tangent, then the area gets direct sunlight and it is warmer.
500
What type of air mass would bring very hot and wet conditions?
Maritime Equatorial (mE)
500
What causes convection?
Warm air is less dense causing it to rise and cool air is more dense causing to sink which creates convection.
500
What kind of a relationship do relative humidity and temperature have if the amount of water vapor stays the same?
They have an inverse relationship. (As temperature rises, relative humidity decreases)
500
CHALLENGE: Name six different types of air masses.
