This is the process by which water vapor is changed back into liquid water.
What is condensation?
100
This is air moving in a specific direction.
What is wind?
100
A violent, whirling wind associated with thunderstorms.
What is a tornado?
100
Rain, sleet, snow, or hail.
What are types of precipitation?
200
A person who studies weather.
What is a meteorologist?
200
These are puffy, white clouds with a flat base that usually signal fair weather, or if they grow large and dark, signal thunderstorms.
What are cumulus clouds?
200
Rain drops that pass through a layer of freezing air near Earth's surface forming pellets.
What is sleet?
200
Stratus clouds that form near the ground.
What is fog?
200
A boundary between 2 different air masses.
What is a front?
300
A measure of the average amount of motion of molecules.
What is temperature?
300
These are high, thin, white clouds made mostly of ice crystals that usually signal fair weather.
What are cirrus clouds?
300
The amount of water vapor in the air.
What is humidity?
300
A severe storm that forms over tropical oceans.
What is a hurricane?
300
A large body of air with the same properties as Earth's surface over which it develops.
What is an air mass?
400
The measurement of the amount of water vapor in the air compared to the amount needed for saturation at a specific temperature.
What is relative humidity?
400
These are low altitude clouds that usually appear in layers or sheets that can signal fair weather, rain, or snow.
What are stratus clouds?
400
The type of pressure system typically seen when the weather is severe (think thunderstorms and tornadoes).
What is a low pressure system?
400
These changes usually occur at fronts. (There are 4, but you have to name 2 in order to get the points for this question.)
What are a changes in temperature, wind direction, pressure, and precipitation?
400
The temperature at which air is saturated and condensation begins.
What is the dew point?
500
Air holding all the moisture if can at a particular temperature.
What is saturated?
500
These are dark rain clouds that can signal rainfall, snow, or stormy conditions.
What are nimbus clouds?
500
Caused by the interaction of air, water, and the Sun.
What is weather?
500
Objects that form as warm, humid air rises, expands, then cools, condensing water vapor into water droplets.
What are clouds?
500
These 2 types of lines connect equal points on a weather map. (In order to receive the points, you must tell me the 2 terms and what equal things they connect.)
What are isobars (pressure) and isotherms (temperature)?
