The Water Cycle
How is a cloud formed?
A cloud is formed when warm air rises and water vapor in the atmosphere within it condenses.
What structures are formed when warm air rises and the water vapor within it condenses?
Clouds
Clouds form through the process of:
Condensation
The process of water changing from liquid into gas is called:
Evaporation
Name and define the process that occurs when the water in a mud puddle disappears.
Evaporation is the process that occurs when water disappears from a mud puddle.
Clouds form via the process of sublimation.
False. Clouds form via the process of condensation.
Snow and rain are forms of condensation.
False. Snow and rain are forms of precipitation.
The water cycle only occurs at certain times during the year.
False. The water cycle occurs all the time.
Farmers use water to __________ their crops.
Irrigate
Ice melting into liquid water is an example of this process:
Phase change
Rain and snow are examples of this process:
Precipitation
Define precipitation and list the forms that it can take.
Precipitation is water that comes back to Earth. It can take the form as rain, snow, sleet, or hail.
List the three forms, or phases, in which water exists.
The three phases are solid, liquid, and gas.
In how many forms does water exist on Earth?
Three
Describe three ways water vapor can be created.
Three ways water vapor can be created is transpiration, boiling, and animals breathing out air.
The process by which plants give off water is called:
Transpiration
A great deal of water vapor evaporates from the oceans.
True.
Approximately 60% of the human body is made up of water.
True.
The continual movement of water between Earth and the air is called (the):
Water cycle
What do animals produce when they breathe out?
Water vapor
