Science weather test review Flashcards
What is weather?
A system of interacting energy
What is solar energy?
The type of light energy that comes from the sun
What is thermal energy?
Energy that has to do with temperatures
Describe conduction
When molecules transfer thermal energy from one end of an object to another by conduction
Describe convection
When warmer, less dense air rises, and cooler, more dense air moves and takes its place
What is a barometer?
A tool scientists use to measure air pressure
What is evaporation?
When liquid water changes into water vapor gas
What is condensation?
When water vapor changes into liquid water
What is precipitation?
When water is released from a cloud back down to earth
What are some examples of precipitation?
Snow, rain, hail, sleet, ect
What are isobars?
Lines on weather maps that represent patterns of Air pressure
What is a front?
When cooler, denser air moves under warmer, less dense air
What is a lift?
When warmer air rises at the front
What type of energy does the sun produce?
Solar energy
What type of energy does the earth’s surface absorb?
the sun’s solar energy
The earth’s crust transforms ______ energy into ______ energy.
Solar energy into thermal energy
The earth’s crust heats the air molecules through the process of . . .
conduction
As a cold front moves in, what happens to the warm air
The warmer air rises
What forms when cold and warm air masses meet?
A front
What direction does warm air go?
Up and rises
What direction does cold air go?
down
Warm air molecules are further apart making the air more or less dense?
less dense
Cool air molecules are closer together making the air more or less dense?
more dense
Do cold or hot air molecules move faster?
Hot
Does cold air have high or low air pressure?
high air pressure
Does warm air have high or low air pressure?
low air pressure
What component of weather does an isobar map show?
Low and high pressure areas
What unit of measurement is used to measure air pressure?
Millibars
What type of clouds are associated with a storm?
cumilonimbus
What device is used to measure air pressure?
barometer
How does a barometer work?
As the air pressure increases, it pushes up the liquid in the tube. The higher the liquid, the higher the air pressure.
