Atmosphere Basics
How many layers does Earth's atmosphere have?
5
This layer of Earth's atmosphere is where most weather takes place and air pollution collects
What is the troposphere
The layers of the atmosphere are separated based on their _________.
What is temperature variations?
These puffy clouds form below 2000m.
What are cumulus clouds?
Water droplets that fall and have a diameter of at least 0.5 mm
What is rain?
The ozone layer absorbs _____________.
What is UV radiation?
This outermost layer of Earth's atmosphere has no clear boundary at the top.
What is the exosphere?
What is 21%?
These layered clouds form low in the atmosphere.
What are stratus clouds?
This precipitation forms irregular lumps of ice in cumulonimbus clouds
What is hail?
What gas makes up 78% of Earth's atmosphere?
What is nitrogen?
This layer of Earth's atmosphere is located above the tropopause and is made up primarily of concentrated ozone.
What is the stratosphere?
These clouds produce no precipitation
Cirrus
These high, often wispy clouds are made of of ice crystals that form at heights of 6000 meters.
What are cirrus clouds?
This precipitation forms fluffy 6 sided ice crystals
what is snow?
All solid and liquid forms of water that fall from clouds is called...
What is precipitation?
This atmospheric layer is just above the stratosphere.
What is the mesosphere?
Why does air pressure decrease as altitude increases?
Gravity pulls gas molecules closer to Earth.
These clouds can signal both fair weather and severe storms.
cumulus clouds
This precipitation falls as a liquid and freezes upon impact with an object
What is glaze?
What is the trend of air pressure in relation to altitude?
Air pressure decreases as altitude increases
Air pressure increases as altitude decreases
This atmospheric layer, just above the mesosphere, has temperatures that increase with altitude due to the absorption of solar radiation
What is the thermosphere?
What heats the bottom of the troposphere?
This is the time when the rate of evaporation and condensation occur at the same time
dew point
This precipitation falls as thin translucent pieces of ice
What is sleet?
