This type of radiation can cause health problems including sunburn and even cancer. Luckily for us, most of it is absorbed by the earth's ozone layer before it ever reaches us.
What is ultraviolet radiation?

While we in the United States still use the Fahrenheit temperature scale, most of the world uses this alternate scale in which water boils at 100 degrees.
What is Celsius?
100
Don't let this "blow" your mind, but air moving from areas of high pressure toward areas of lower pressure is also known by this name.
What is wind?
100
When clouds form in a solid layer that spreads across the sky, we say that this type of cloud is present.
What is stratus?

This form of precipitation is the most common form found on earth.
What is rain?

Objects that reflect every wavelength of visible light back toward your eye appear to be this color.
What is white?

When the temperature of a substance increases, its molecules move faster and do this.
What is expand (or spread apart)?
200
This process, caused by the rotation of the earth, causes wind to travel in a curved path.
What is the Coriolis effect?
200
This measurement will let you know how much water vapor is in the air.
What is humidity?
200
The crystals of this type of precipiation can take on many shapes, but they are always six-sided.
What is snow?
300
In this process, energy from the sun is trapped by certain gases in our atmosphere, causing the planet to get warmer.
What is the greenhouse effect?
300
The Kelvin temperature scale begins at this impossible temperature at which molecules become completely motionless.
What is absolute zero?
300
This type of wind begins over an ocean or lake and blows toward land?
What is a sea breeze?
300
This step of the water cycle can keep you cool when it happens to the sweat on your skin.
What is evaporation?
300
This sometimes destructive type of precipitation which only forms in cumulonimbus clouds consists of many-layered pellets of ice.
What is hail?
400
Energy from the sun heats the earth's surface. Some of that energy travels back into the atmosphere in the form of this type of radiation, causing the air to get warmer.
What is infared radiation?
400
Much of the atmosphere is warmed by this process involving rising and sinking currents of air.
What is convection?
400
This piece of equipment can tell you how fast the wind is blowing.
What is an anemometer?
400
When the air cools down to this temperature, clouds or other forms of condensation begin to occur.
What is the dew point?
400
This type of precipitation forms when raindrops freeze before they hit the ground.
What is sleet?
500
Methane and water vapor, along with this other gas help keep the earth warm by trapping the sun's energy.
What is carbon dioxide?
500
A barometer would show an increase in this atmospheric measurement when cool air sinks toward the ground.
What is air pressure?
500
This global wind belt is the reason that storms in the United States tend to approach mainly from the west.
What are the prevailing westerlies?
500
This prefix, when used in the name of a cloud, indicates a cloud of medium altitude.
What is alto?
500
Nimbostratus clouds sometimes produce this type of rain made up of very small drops.
