100

Water vapor is given off through the leaves in this process...

What is Transpiration 

100

When cold and warm air fonts meet, but neither one can move the other

Stationary front

100

Form over oceans and are very humid

Maritime air masses

100

Meteorologist

A person who studies and predicts weather

100

Process where water vapor becomes liquid

Condensation

200

Sunlight heats up the earth's surface and draws water out into the atmosphere 

What is evaporation 

200

Forms when a cold air mass runs into a warm air mass and may cause heavy rains, wind, thunderstorms, and even tornadoes.

Cold Front

200

This air mass has less exposure to moisture, and are drier. 

Continental Air Mass

200

Precipitation

Falls from the clouds in the form of hail, snow, rain, or sleet. 

200

Band of high-speed winds about 10km above Earth's surface. 

Jet stream

300

Water can stay below ground for a very long time in large what? 

What is Aquifers
300

Forms when a fast-moving war air mass overtakes a slower-moving cold air mass. This may cause rain and clouds for a few days. 

Warm Fronts

300

form in the tropics and have low air pressure. 

Tropical Air Mass

300

Air Mass

a huge body of air that has similar temperature, humidity, air pressure at any given height.

300
high-pressure center of dry air

Anti-cyclone

400

What is the process in which water seeps into the ground and stays for periods at a time. 

What is infiltration

400

A warm air mass get caught between two cold air masses

Occluded front

400

What would a warm air mass passing over the ocean most likely cause?

Rainfall

400

Cyclone

swirling center of low air pressure

400
Boundary where air masses meet

Front

500

Toxic runoff can pollute a stream and also what? 

Groundwater

500

What is the major cause of ocean waves? 

Wind

500

What moderates air temperatures?

Large bodies of water. 

500

Coriolis Effect

The invisible force that appears to deflect the wind and is responsible for currents' circulation pattern.
