100
Is the picture showing conduction or convection?
Convection
100
Which direction is the wind blowing in the southern hemisphere?
Counterclockwise
100
What is this weather symbol?
Hurricane
100
Define Wind
movement of air from areas of high pressure to areas of low pressure
100
Type of weather at a high pressure system
Warm, clear and sunny skies
200
The sun's energy hits Earth...
Unevenly
200
True or False
A Jet Stream is a narrow band of strong winds that blow in the upper troposphere. Jet Streams influence local weather by causing the shifting around of warm and cold air masses.
True
200
Which devastating hurricane made landfall in Texas and Louisiana in August 2017 and was a category 4 hurricane?
Harvey
200
Define Air Mass
large body of air that has similar temperature and humidity throughout
200
Define Sun
The primary source of energy that drives convection within the atmosphere and oceans is
300
What does atmospheric convection produce?
Weather
300
Identify each type of weather front
1) Cold Front
2) Warm Front
3) Occluded Front
4) Stationary Front
300
Which type of pressure system causes the warm, moist air to rise and supplies the hurricane with fuel?
Low Pressure System
300
La Nina
global wind phenomenon will increase the likelihood of hurricanes forming
300
Define Hurricane
large, rotating storm system that forms over water, bringing high winds, rough seas, and heavy rain
400
How do temperatures at the poles differ from temperatures at the equator?
Temperatures at the poles are much lower
400
Which direction is the wind blowing in the northern hemisphere?
Clockwise
400
Where do hurricanes occur/develop?
ocean water is the warmest, near the equator in the late summer
400
Define Coriolis Effect
result of air flowing in a curved pattern because of the Earth's shape, tilt, and uneven heating of the Earth by the sun
400
Define El Nino
In years when the winds are blowing East to West die down and warm ocean water moves West to East bringing more rainfall than normal.
500
Earth's atmosphere and oceans transfer heat through the evaporation and movement of water, producing
wind and ocean currents
500
Describe the type of weather that the Northwest is and was experiencing over the last few days?
Cold, rainy, low pressure system
500
Changes in ocean temperature affect weather because they influence interactions between the?
air and water at the ocean surface
500
Define Front
what it is called when two air masses of different temperature and densities meet but do not mix. Also known as the boundary between two air masses
500
Type of weather at a low pressure system
cloudy and possible precipitation
