This is the lowest layer of the atmosphere. It has the highest air pressure, and it extends from earth up to 16 km. This makes it the layer we live in and the lowest layer. It is the densest layer and is heated from the ground up.
What is trophosphere
100
This is the layer of the atmosphere in which the ozone layer is found. The temperature increases with altitude in this layer and this is the layer in which airplanes fly.
What is stratosphere
100
This layer of the atmosphere is the coldest. As the altitude in this layer increases the temperature decreases. Most incoming meteors from space burn up when they enter this layer.
What is mesosphere
100
This is the largest layer of the atmosphere. The temperature of this layer depends on the solar activity. The temperature of this layer increases with altitude.
What is thermosphere
100
The force per unit applied on a surface by the air above the it.
What is air pressure
200
Low lying, grey clouds that can be the result of a thick fog that has been lifted. Fairly low at 1.2 miles high.
What is stratus
200
Cotton candy like clouds with flat bottoms. About 2.5 miles high.
What is cumulus
200
Thin wispy clouds indicating a day with fair weather. Have a high elevation of about 6 miles.
What is cirrus
200
The movement caused by the tendency of hotter, and therefore less dense material to rise, and cooler, more dense material to sink.
What is convection
200
A storm with thunder, lightning and normally also heavy rain or hail.
What is thunderstorm
300
This forms when a warm and cold air masses meet and the cold air mass pushes the warm air mass and causes the warm air mass to rise. Brings steady rain or snow.
What is cold front
300
A large quantity of air in which temperature and humidity are almost the same.
What is air mass
300
This forms when a cold air mass and a warm air mass meet. The warm air mass pushes the cold air mass and slowly rises over it. Brings short but heavy storms.
What is warm front
300
This occurs when a warm and cold air mass meet and remain at a stand still. Brings cloudy skies for as long as it remains.
What is stationary front
300
the state of the atmosphere at a given time
What is weather
400
Any rain, sleet, snow or hail that falls to the ground.
What is percipitation
400
A form of precipitation consisting of ice pellets mixed with rain or snow.
What is sleet
400
water that falls from the sky
What is rain
400
atmospheric water vapor frozen into ice crystals and falling to the ground in flakes.
What is snow
400
Ice pellets that fall from the sky
What is hail
500
The movement of water on earth. Goes through the steps: evaporation, transpiration, condensation, precipitation, and groundwater/ runoff.
What is the water cycle
500
How hot or cold something is.
What is temperature
500
How fast and in what direction wind is blowing
What is wind speed and direction
500
This forms from two clashing air masses that have different conditions. Require polar air from the north and moisture from the north Atlantic, the pacific ocean and the gulf of mexico.
