These are the three main types of clouds classified by Luke Howard.
What are cumulus, stratus, and cirrus?
This is the name for the state of the atmosphere at a specific place and time.
What is weather?
This is the lowest layer of the atmosphere where we live.
What is the troposphere?
This is what warm air does: rise or sink.
What is rise?
This instrument is used to measure air pressure.
What is a barometer?
This type of cloud is thin, wispy, and found high in the sky.
What is a cirrus cloud?
This tool is used to measure air temperature.
What is a thermometer?
This atmospheric layer is where airplanes usually fly.
What is the stratosphere?
This is denser: warm air or cold air.
What is cold air?
When this drops, stormy or rainy weather is likely.
What is pressure?
This cloud type is known for bringing thunderstorms.
What is a cumulonimbus cloud?
These violent, spinning columns of air extend from a thunderstorm to the ground in flat areas and can cause major destruction.
What is a tornado?
In this atmospheric layer, meteors burn up.
What is the mesosphere?
This force allows hot air balloons to float.
What is buoyancy?
This is the main source of heat for Earth’s atmosphere.
What is the sun?
This type of cloud forms in flat layers and often brings overcast skies.
What is a stratus cloud?
This is the process of water vapor cooling and forming clouds.
What is condensation?
This is the hottest atmospheric layer, where auroras occur.
What is the thermosphere?
This happens to the density of air as altitude increases.
What is "it decreases?"
In the troposphere, this happens to air temperature as altitude increases.
What is "it decreases"?
This cloud type is a combination of cumulus and stratus and brings steady rain.
What is a nimbostratus cloud?
This is the scientific term for when liquid water turns into a gas.
What is evaporation?
This atmospheric layer fades into space.
What is the exosphere?
This happens to an object when its density is greater than the fluid it is placed in.
What is it sinks?
When warm air rises and cool air sinks, this process is occurring.
What is convection?
