Atmosphere
This is the first layer of the atmosphere, where most of our weather occurs, and planes fly
Troposphere
This cloud is big and puffy
Cumulus cloud
Heat energy comes from where?
The sun
Liquid water falls as what?
Rain
The air that surrounds Earth or another body in space is called this
The atmosphere
This is the last layer of the atmosphere, it has the thinnest air.
Thermosphere
This is a low-lying gray cloud
Stratus cloud
This is the first step in the water cycle. Liquid turns into a gas(creating water vapor)
Evaporation
This is what we call moving air
Wind
This is an instrument that measures air pressure
Barometer
21% of our atmosphere is made up of this
Oxygen
This is a high-altitude cloud made of ice crystals
Cirrus cloud
This is the second step in the water cycle (when clouds form)
Condensation
The form that water takes depends on what?
The temperature of the air
This is the weight of gasses pressing down on the Earth (it changes)
air pressure
This is a thin layer of gas within the stratosphere that filters out much of the harmful radiation from the sun
Ozone
Cumulus clouds usually signal what type of weather?
Good weather (sunny, nice)
This is the last step in the water cycle (when liquid falls from the sky)
Precipitation
When water is below freezing it can fall as these types of precipitation: (List all 3)
Snow, sleet , and hail
When air becomes less dense and moves up (warm air) and colder air sweeps into the empty space
convection current
This layer of the atmosphere helps provide radio signals
Ionosphere
Stratus clouds are often a sign of what type of weather?
Rain!
The temperature when water vapor turns back into a liquid
dew point
The amount of water in the air at any given time is called the level of what?
Humidity
This is when warm air over land rises and the cooler air over water (lakes, rivers, and oceans) rushes in
Sea breeze
