Water & Weather
When moisture falls from the sky as rain, snow, sleet, or hail, it is known as this.
What is precipitation?
These are low, gray clouds that often bring drizzle or light rain.
What are stratus clouds?
These forms where warm and cold air masses meet.
What are fronts?
This is a violent, rotating column of air that moves in a narrow path over land.
What is a tornado?
This is a scientist who studies and forecasts the weather using data from many sources.
What is a meteorologist?
When water changes from a liquid to a gas, the process is called this.
What is evaporation?
These are high, white, feathery clouds usually linked with fair weather.
What are cirrus clouds?
This is a large body of air that has the same temperature and humidity throughout.
What is an air mass?
These forms as balls of ice inside strong thunderstorms.
What is hail?
This is the amount of water vapor in the air.
What is humidity?
These are thick, puffy clouds often associated with fair weather.
What are cumulus clouds?
This compares how much water vapor the air is holding to how much it can hold at a certain temperature.
What is relative humidity?
This is a line on a weather map that connects places with the same temperature.
This is the temperature at which air becomes saturated and condensation forms.
What is the dew point?
These clouds produce the majority of precipitation.
What are nimbus clouds?
When water vapor cools and changes back into liquid droplets, it is called this.
What is condensation?
Tornadoes often form from a part of a thunderstorm called this.
What is a wall cloud?
This forms when snow melts as it falls and then refreezes near the ground.
What is sleet?
Air is this when it holds all the water vapor it possibly can.
What is saturated?
These usually bring fair weather because air sinks, making it difficult for clouds to form.
What are high pressure systems?
A hurricane is a powerful storm that forms over these.
What are warm tropical oceans?
This results from the interaction of air, water, land, and energy from the sun.
