A layer extending an average of 12 km above Earths surface.
Troposphere
When air temperature increases with altitude an the air becomes stable.
Temperature inversion
A natural process in which certain gases in the atmosphere warm a planet as they absorb and emit infrared radiation.
Greenhouse effect
How are the atmospheres divided into their layers?
Based on composition and temperature.
What is the atmosphere air mainly made up of.
Nitrogen:78%, Oxygen: 21%
What is the remaining 1% of other gases left in the atmosphere called?
Trace gases majority is argon.
Does temperature increase or increase with altitude in the troposphere.
Decrease.
How many layers are in Earths atmosphere.
5
What are the names of the layers from close to earth going up?
Troposphere, stratosphere, Mesosphere, Thermosphere, exosphere
Which layer is the Ozone found in?
Stratosphere.
In the stratosphere does the temperature increase or increase with altitude?
Increase.
Does the temperature increase or decrease with altitude in the Mesosphere.
It decreases in the lower parts of the Mesosphere the higher part of the Mesosphere increases.
Does the thermosphere and Exosphere impact weather?
No
A narrow ban of fast moving, high-altitude air.
Jet stream
The apparent reflection of an object due to Earths rotation.
Coriolis effect
A large volume of air with uniform moisture and temperature throughout.
Air mass
Air masses interact in these zones.
Weather fronts
How many jet streams are there in the world?
4
How many pressure systems are there?
2
What is a low pressure system also known as?
Low(L)
Which direction does a low pressure system flow?
counter-clockwise
What are some results of a low pressure system?
Since air rises clouds will form and precipitation can happen.
What is a high pressure system also known as?
High (h)
Which direction does a high pressure system flow?
clockwise.
