100
the three things needed to form a cloud
What is water vapor, small particles (dust, pollen, salt), and a drop in air pressure
100
what are the four types of precipitation?
rain, snow, sleet, & hail
200
the constant cycling of water between the atmosphere and the hydrosphere
What is the water cycle
200
you have to wear an oven mitt when you pick up a boiling pot of water because of this
What is conduction
200
places near the equator are generally hotter because
the sun hits those areas more directly
200
what are cirrus clouds made of and where do they form
ice crystals; high in the troposphere
200
what temperature does it have to be for rain to form?
it has to be above freezing near the cloud and near the ground
300
when the heat from the sun changes a liquid to a gas.
What is evaporation
300
cold air is ________ dense so it _________
more dense so it sinks
300
air moves from ________ pressure areas to ______ pressure areas.
high to low
300
what do cumulus clouds look like?
fluffy cotton
300
what temperature does it have to be for snow to form?
it has to be below freezing near the cloud and near the ground
400
When water vapor cools and turns into water droplets
What is condensation
400
a microwave cooks your food because of
radiation
400
the amount of water vapor in the air
What is humidity
400
which cloud can cause thick fog
stratus
400
what temperature does it have to be for sleet to form?
it is above freezing near the cloud (leaves as rain) but below freezing near the ground (freezes up)
500
when water infiltrates the Earth and collects underground. This is where we get our drinking water.
What is groundwater
500
steam rises out of your cup of hot chocolate. Steam is formed by ___________. It rises because of _________.
condensation; convection
500
when water droplets combine and become heavy in the clouds, they fall as ___________
precipitation
500
how do clouds form
warm air rises, cools off, and condenses around dust and salt.
500
what temperature does it have to be for hail to form?
it is below freezing near the cloud. Wind pushes the ice back up into the cloud before it finally falls. It can be above freezing near the ground.
