The Water Cycle
This describes the way that water moves through the Earth's systems
What is The Water Cycle
This is a major factor in condensation
What is temperature
A measure of the amount of water vapor in the air
What is humidity
Any form of water that falls from clouds and reaches Earth's surface
What is precipitation
This is used to measure rain fall
What is a rain gauge
This heats the land, ocean, and lakes
What is the sun
Liquid water that condenses from the air onto a cooler surface
What is dew
The ability of air to hold water depends on this
What is temperature
The most common type of precipitation
What is rain
One way to measure snowfall
What is a simple measuring stick
These are formed through evaporation, transpiration, and respiration
What are clouds
These form when water vapor in the air condenses to form liquid water or ice crystals
What are clouds
The percent of water vapor in the air compared to the maximum amount of water vapor the air can hold at a certain temperature
What is relative humidity
This forms when water vapor in a cloud is converted directly into ice crystals that clump together
What is snow
Another way to measure snowfall
What is melting collected snow and measuring the depth of water it produces
This falls from clouds towards Earth's surface
What is precipitation
The temperature at which condensation begins
What is the dew point
This device can measure relative humidity
What is a psychrometer
A round pellet of ice at least 5 millimeters in diameter
What is a hail
A scientist who studies weather
What is a meteorologist
Together these drive the never-ending water cycle
What are gravity and the sun
This occurs when water vapor changes into liquid water
What is condensation
This term describes air that has reached 100 percent relative humidity
What is saturated
Rain starts out as these
What are cloud droplets
On average 10 centimeters of snow contain this amount of water
What is 1 centimeter of water
