100

This layer of the atmosphere is where all weather occurs.

Troposphere

100

This causes weather systems to form on Earth.

Sunlight heating the Earth's atmosphere and surface unevenly

100

These two types of air currents meet to form a tornado.

Hot, fast, upward-moving air and cold, downward-moving air

100

A falling barometer indicates this

Storm approaching / air pressure dropping

100

A red sky at sunrise signals this.

Bad weather approaching

200

This gas is known as the greenhouse gas because it traps heat.

Carbon dioxide (CO₂)

200

Clouds are classified by these two things.

Appearance (shape) and height in the atmosphere

200

This scale rates tornado intensity, and this scientist created it in 1971.

Enhanced Fujita (EF) Scale, created by Dr. Tetsuya Fujita

200

What is The Doppler Effect? 

Change in frequency of a wave as its source moves toward or away from an observer

200

This letter on a weather map indicates stormy weather is likely.

L (Low pressure)

300

Name all four layers of the atmosphere from bottom to top.

Troposphere, Stratosphere, Mesosphere, and Thermosphere

300

These are the three ingredients needed to form a cloud.

Water vapor, rising air, and dust particles

300

This is the difference between a tropical cyclone and a hurricane

Location — hurricanes are in the Gulf of Mexico and the Atlantic

300

Closely spaced isobars on a weather map indicate this.

Strong winds / a sharp change in pressure over a short distance

300

Name any five types of clouds.

Cirrus, stratus, cumulus, cumulonimbus, nimbostratus, altostratus, altocumulus, cirrostratus, stratocumulus, cirrocumulus

400

This is the most important factor in determining an area's climate.

Latitude

400

This is the difference between fog and smog.

Fog is a cloud at ground level; smog is caused by air pollution

400

This is what conditions are like inside the eye of a hurricane.

Calm winds, clear skies, and very low pressur

400

A weather front is this — name both main types.

Boundary where two air masses meet — warm front and cold front

400

On Doppler Radar, precipitation rotating with some moving toward the station and some moving away indicates this — and a meteorologist would do this next.

Mesocyclone — she would issue a tornado warning for the storm's path

500

These two factors influence Earth's overall climate.

Energy from the sun, and ocean/atmosphere currents that circulate heat

500

These are convection currents, and this is what they do in the atmosphere.

Cycles of warm air rising, cooling, and sinking — they circulate heat and drive weather

500

This is why you should never shelter under a highway overpass during a tornado.

The overpass acts like a wind tunnel, accelerating the winds and increasing danger

500

This is how Doppler Radar detects a possible tornado before it touches down.

It detects rotating precipitation — some moving toward the station, some away — indicating a mesocyclone

500

Buys Ballot's Law: stand with your back to the wind — the storm is in this direction.
