The direct transfer of heat from one substance to another substance that it is touching.
radiation
density
conduction
volume
a measurement that describes how closely packed the air particles are
volume
density
conduction
temperature
A thin layer of gases surrounding Earth
atmosphere
molecules
particles
altitude
height above the ground
atmosphere
air
density
altitude
How is air temperature related to altitude?
the higher up the warmer it is
the higher up the colder it is
there is no relationship
How does air warm up?
the sun hits the air molecules and they heat the earth's surface
air molecules get energy from the surface of earth by conduction
the center of earth gives off heat
What happens to air for it to become more dense?
It loses energy
It gains energy
Precipitation is
how closely packed water molecules are
how fast air molecules move
water falling from clouds
the reason air warms up
Air particles that gain thermal energy will move faster, spread farther apart and become
more dense and sink
less dense and rise
turn into a cloud
Air particles that lose thermal energy will slow down, come closer together to become
more dense and sink
less dense and rise
turn into a cloud
Evaporation is when
molecules of water filter into the ground
molecules of liquid water escape as water vapor
ice meltis to a liquid
water vapor sticks to dust in the atmosphere
when water vapor molecules in the air slow down and "stick" together to form droplets of liquid.
evaporation
condensation
precipitation
density
These are what water vapor needs to condense on to form clouds
oxygen
air
condensation nuclei
hail
What is the start of cloud formation?
wind blowing
the sun's energy
cold air sinking
warm air rising
What is the process called when liquid water gains enough energy and some of the molecules escape as vapor (gas)?
condensation
evaporation
freezing
melting
When a parcel of air rises it gives energy to the surrounding air, cools off and becomes _______ dense.
more
less
Water droplets attach to ______________ to form clouds.
dust
gas
rain
water vapor molecules lose energy, stick together and form a liquid?
evaporation
relative humidity
melting
condensation
Millions of tiny ___________________ clump together to form a cloud.
water droplets
gases
cotton balls
Clouds are made of
water droplets or ice crystals
Water vapor molecules
cotton
Warm air rises becasue
it loses energy and becomes more dense
gains energy and becomes less dense
the wind blows it around
