The layer with the highest pressure and weather occurs here.
Troposphere
Condensed water in the clouds gets heavy enough to fall back to earth.
Precipitation
Thunder can be heard and lightning can be seen.
Thunderstorm
This front has cold, dense air. Thunderstorms or ice storms can occur during the front.
Cold front
This weather tool measures wind speed
Anemometer
The Ozone layer is here.
Stratosphere
Plants releasing water vapor into the air.
Transpiration
A huge twister that creates large masses of destruction.
Tornado
This front has warmer and less dense air. Light rain occurs in the front.
Warm Front
This weather tool measures air pressure
Barometer
This is the coldest layer. This is also the 3rd layer in the atmosphere.
Mesosphere
Water changing from a liquid to a gas
Evaporation
Large amounts of rain and are classified in categories.
Hurricanes
Warm and cold air mass meet but don't have enough force to push the other one. The resulting weather is light rain for days.
Stationary Front
This weather tool measures wind direction
Wind Vane
This is the hottest layer and right above the mesosphere.
Thermosphere
Water will always try to make its way to the lowest point
Surface Water Flow
These clouds are thunderstorm clouds.
Cumulonimbus clouds
This pressure system has rain and stormy weather and also colder than usual.
Low pressure system
This weather tool measures relative humidity
Sling Psychrometer
This is the highest layer in the atmosphere.
Exosphere
Water will continue to run downward even if it is underground
Ground Water Flow
These clouds indicate fair weather. They are long thin clouds.
Cirrus Clouds
This pressure system indicate fair weather, warm temperatures, slight breeze, cirrus and cumulus clouds.
High Pressure System
This weather tool measures actual humidity
Hygrometer
