200
This is created by differences in air pressure and temperature.
What is wind?
200
The percentage of water vapor in the air compared to the maximum amount of water vapor the air can hold at a particular temperature.
What is relative humidity?

When water vapor in a cloud is converted directly into ice crystals.
What are snowflakes?
300
This instrument has two thermometers and can measure relative humidity.
What is a psychrometer?
400
This type of heat transfer is made by rising warm air and sinking cool air.
What is convection current?
400
This type of breeze forms at night because land cools faster than the ocean.
What is land breeze?

400
When rain drops freeze in the air into ice particles smaller than 5 millimeters in diameter.
What is sleet?
400
In this cycle, water moves from oceans, lakes, and plants into the atmosphere, then falls back to Earth.
What is the water cycle?
500
A type of heat transfer that takes place when one touches a hot cup of tea.
What is conduction?
500
The trade wind, the polar easterlies, and the prevailing westerlies.
What are global wind belts?
500
Clouds that form near the ground when the ground cools at night after a warm, humid day.
What is fog?
500
When raindrops freeze when they touch a cold surface.
What is freezing rain?
500
The way Earth's rotation makes wind curve.
