Atmosphere Basics
What is the name for a large body of air with similar temperature and humidity?
air mass
Which cloud type is thin, wispy, and often indicates fair weather but can precede storms?
cirrus
Which front is the leading edge of a mass of hot, moist air overtaking cool, dry air?
warm front.
What large, rotating storm forms over the ocean with strong winds and low pressure?
hurricane
The heat transferred from the Sun to the Earth by waves is called what?
radiation
Winds are named according to the direction from which they blow. (True/False)
True
Snow, sleet, hail, and rain are all examples of what process in the water cycle?
precipitation
On weather maps, what symbol typically represents a quick-moving cold front?
a solid blue line with triangles pointing in the direction the front is moving (teacher note: quick-moving cold front symbol typically is blue with triangles).
Doppler radar shows a vertical rotating column of air with high wind speeds. What is most likely occurring?
formation of a tornado
A pot is placed directly on a stove and gets hot. Which heat transfer process primarily causes the pot to heat up?
conduction (teacher note: stove-top heating is conduction between pot and burner; some answers list convection for liquids)
Which force causes winds to be deflected to the right in the Northern Hemisphere and left in the Southern Hemisphere?
Coriolis effect.
Which cloud type is most associated with severe weather and thunderstorms?
cumulonimbus
Which front is most likely associated with several days of continuous snowfall?
stationary front (or occluded depending on context; document's answer: cold front — check class emphasis).
How can a cold front cause severe weather when it moves into a warm air mass? (short explanation)
Cold, dense air moves under warm air, forcing it up rapidly; rising moist air cools and condenses, producing strong convection and thunderstorms
Order these EMS waves from lowest to highest energy: Ultraviolet, Visible, X-ray, Radio wave, Infrared, Gamma, Microwave.
Radio wave, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma
What term describes the narrow zone of strong winds high in the troposphere that influences weather patterns?
Jet stream
Which cloud type is most associated with tornado formation?
cumulonimbus
Given a scenario: A cold front moves into a warm, moist region. Explain the sequence of weather events that can lead to thunderstorms (3–4 short points).
Low-pressure systems typically bring clouds, precipitation, and unsettled weather.
Which conditions are most associated with hurricanes? (choose the best set)
low pressure, high winds, and warm water temperatures.
Which section of the electromagnetic spectrum is the only one visible to the human eye?
Visible light
Describe how air moves between high- and low-pressure areas (short answer).
Winds move from high-pressure areas toward low-pressure areas, often causing air to rise in low-pressure zones.
A weather map shows a curved line with semicircles attached to a low-pressure system. Which type of front does this symbol indicate and what change in temperature is most likely?
Warm front (semicircles on the map) — temperatures will generally increase (warm front approaching).
Given a scenario: A cold front moves into a warm, moist region. Explain the sequence of weather events that can lead to thunderstorms (3–4 short points).
Cold air undercuts warm air, forcing warm moist air upward, leading to rapid condensation and possible thunderstorms/tornadoes.
Compare blizzards and thunderstorms — name one major similarity and one major difference.
Similarity — both can include high winds; Difference — blizzards involve heavy snow and cold temperatures, thunderstorms involve rain and often lightning.
What happens to frequency when energy increases? (choose and justify in one sentence)
Frequency increases as energy increases.
