10 QUESTIONS ONAIR MASSES AND FRONT
Eric Angat
Science teacher
EEN 2.5.2
Essential Question:
How do I explain the movement of air masses and their effect on weather?
Comparing Weather and Climate
Weather Climate
Both weather and climate deal with the condition of the atmosphere.
Day to day (shorter time)
Years(longer time)
1. What is the major difference between weather and climate? A. air temperature B. air pressure C. humidity D. time
2. Which of the following is an example of climate?
A. The current temperature in Pinehurst, NC B. The relative humidity in Atlanta C. The average current temperature in a region D. The average temperature in Winston
Salem,NC over the past 30 years
3.Decribe the 4 different types of air masses?
Maritime air mass
Tropical air mass
Polar air mass
Continental air mass
Cold air coming from the North, North East, NW
Humid air coming from the oceans
Warm air coming from the South, South East, SW
Dry air coming from Canada and Mexico
Warm or hot region because of its nearness to the equator.
Cold region because of its nearness to the North pole.
4. What are the common characteristics of the air masses in United States?
Warm or hot region because of its nearness to the equator.
Cold region because of its nearness to the North pole.Maritime
Polar (cold and humid)
ContinentalPolar (cold and dry)
Maritime Polar (cold and humid )
Maritime tropical(warm and humid )

5. Which type of heat transfer moves warm water away from the equator?A. conductionB. convectionC. radiationD. inversion
Weather front
A weather front is a place where air masses meet.
Cold air mass
Warm air mass
WeatherFront
Results to Changes in
Weather.
Cold front
A weather front is a place where air masses meet.
Cold air mass
Warm air mass
Results to thunderstorms,
tornado, storms
WeatherFront
Warm front
A weather front is a place where air masses meet.
Warmair mass
Cold air mass
Results to mild to
moderate precipitation

6. How are hurricanes and tornadoes related to air masses? A. They form where air masses
meet. B. They form where air pressure is
the same. C. They form where air temperatures
are the same D. They form within air masses.
Most violent weather. Thunderstorms and tornadoes.
Less violent weather (light to moderate precipitation)
changes from higher to lower temperatures
Characterized by storms that are dissipating or dispersing.
Causes flooding due to continuous rain.
7. What are the four types of fronts and the weather they bring?
Occluded Front
Warm Front
Cold Front
Stationary Front

8. Describe the direction of the following weather fronts?
Cold front-violent weather
Moves to the direction of the cold air mass
Cold air mass
Warm front - light or moderate rain.
Moves to the direction of the warm air mass
Warm air mass
Moves to the direction of the cold air mass
Occluded front-appears when storms disperse.
Stationary or does not move.
Stationary front- long days of rain ( flood).
