The Atmosphere
The higher you go into the atmosphere, the temperature will....
decrease/get colder
When water goes from a liquid to a gas its called...
Evaporation
When water goes from a gas to a liquid its called
condensation
Humidity is the
total amount of water in the air
What two variables must be included in a hypothesis?
IV and DV
in the atmosphere, water condenses onto
dust particles
When water falls to the earth as rain, sleet, ice, hail, or snow, what is that called?
Precipitation
What FORCE causes precipitation to fall?
gravity
Heat always moves from
hotter objects to cooler objects
What is your IV?
IV - I change
What YOU control as the scientist
Condensation happens faster in _________ air
cooler
Why is the water cycle considered a cycle?
Its the continuous movement of water/never stops
Precipitation falls because the droplets...
become to heavy
Heat moves until what is reached?
an equillibrium
What Axis does the Dependent Variable go on?
The Y axis
When water vapor rises into the troposphere, the water vapor will change into...
condensation
When water vapor is cooled, the movement of the molecules will...
slow down
When water vapor heats up, molecules will move...
faster and faster
Warmer air can hold...
more water vapor
Name at least 3 things you MUST include in your data table
Title
Labels
IV
DV
Multiple Trials/Trial and Control
Averages (if needed)
Weather only happens in what layer of the atmosphere?
The troposphere
Where does the water cycle need an energy INPUT
during evaporation
Where does the water cycle LOSE energy?
During condensation
Why are Missouri summers MUCH more humid than in the winter time?
Because warmer temperatures can hold more water vapor in the air due to the increase in energy.
Colder temperatures do not hold onto as much air due to the decrease in energy
What is a control variable?
what you compare your results to
