100
blanket of gases that surrounds a planet
What is atmosphere
100
a very large body of air that has a similar temperature and humidity throughout
What is air mass
100
precipitation that falls from clouds through above freezing temperatures
What is rain
100
how do the gases in the Earth's atmosphere differ from place to place
they are about the same from place to place
200
the measure of force with which air particles push on matter
What is air pressure
200
the boundary that forms between air masses
What is front
200
flat, white cloud that can produce a steady drizzle
What is stratus
200
How would air pressure change as you drove up a mountain road
air pressure is greatest at the Earth's surface, so air pressure going up a mountain would decrease
200
what do you do in each of the following: thunderstorm hurricane tornado
find shelter in building or car have a disaster kit & plan already made, evacuate find shelter underground-basement, go to inside room
300
the amount of water vapor the air actually contains compared with the amount it could hold at a given temperature
What is relative humidity
300
scientist who studies weather
What is meteorologist
300
precipitation that falls from clouds through below freezing temperatures
What is snow
300
thermosphere, mesosphere, stratosphere, troposphere
What are the layers of the Earth's atmosphere
300
what is difference between weather and climate
weather is condition of atmosphere at a particular time climate is pattern of weather in an area over a long period of time
400
the amount of water vapor in the air
What is humidity
400
a pattern of weather that occurs in an area over a long period
What is climate
400
thin, feathery could that forms high in the atmosphere
What is cirrus
400
when clouds form, why don't the water droplets in them fall to the ground immediately
a cloud must have a lot of moisture (be full) before it can produce precipitation - drops must be large enough to fall
400
which moves more quickly - a cold front or a warm front
What is cold front
500
condition of the atmosphere at a particular time and place
What is weather
500
dark, heavy cloud that can result in a thunderstorm
What is cumulonimbus
500
raindrops that freeze when they hit a freezing surface
What is freezing rain
500
how are air masses and fronts related
a front is a boundary between air masses
500
what type of clouds help keep the Earth warm by trapping heat from solar radiation in the atmosphere
What is cirrus
