This type of radiation is dangerous, potentially causing sunburns and skin cancer.
What is ultraviolet radiation?
100
While the United States still uses the Fahrenheit scale for measuring temperature, most of the world now relies on this scale based on the behavior of water.
What is the Celsius scale?
100
Wind always flows between two areas where there is a difference in this.
What is air pressure?
100
In this step of the water cycle, water falls from the sky in the form of rain, snow, sleet or hail.
What is precipitation?
100
This type of "puffy" cloud indicates fair weather.
What are cumulus clouds?
200
Of all of the colors of visible light, this one has the longest wavelength.
What is red?
200
On the Fahrenheit scale, water boils at 212 degrees and freezes at this temperature.
What is 32 degrees?
200
During the daytime, the land is typically warmer than the ocean resulting in this salty-smelling local wind.
What is a sea breeze?
200
This measurement indicates how close the air is to being completely full of water vapor.
What is relative humidity?
200
These wispy high-altitude clouds are so cold they are made of ice crystals.
What are cirrus clouds?
300
An object that reflects all colors of visible light appears this color to our eyes.
What is white?
300
In this type of current, hot air rises leaving an area of low air pressure while cooler air sinks creating a region of higher air pressure.
What is convection?
300
In the United States, prevailing winds tend to blow from the west, but this easterly wind belt dominates weather in the tropics.
What are trade winds?
300
When air cools down to this temperature, the water vapor in it begins to condense.
What is the dew point?
300
A sheet of clouds that covers the sky at a mid-level altitude would be known by this name.
What are altostratus clouds?
400
Gases such as water vapor, methane and this gas - caused by the combustion of fuel - help to trap heat in the earth's atmosphere.
What is carbon dioxide?
400
When heat moves between two objects that are in direct contact, we say that this type of heat trasfer is occuring.
What is conduction?
400
This area of low pressure around the equator is known for its lack of wind as well as heat and heavy precipitation.
What are the doldrums?
400
This process which naturally cools your body happens much more slowly on days where the relative humidity is high.
What is evaporation?
400
These clouds, also known as thunderclouds, can bring hail and tornadoes if the storm is strong enough.
What are cumulonimbus clouds?
500
During this process, the earth absorbs energy from the sun and releases it back into the atmosphere in the form of infrared radiation.
What is the greenhouse effect?
500
At this temperature, molecular motion would completely stop.
What is absolute zero? (zero Kelvin)
500
Winds travel in a curved path due to the earth's rotation, a process known by this name.
What is the Coriolis effect?
500
Relative humidity can be measured using one of these devices which consists of two thermometers, one wrapped in a piece of wet cloth.
What is a psychrometer?
500
These clouds look like tiny puffs of cotton from the ground because they form at such high altitudes.
