What are the layers of the earth
Troposphere Stratosphere Mesosphere Thermosphere Exosphere
What are 3 features of the troposphere
Layer closest to Earth, containing half of earths atmosphere Almost all water and dust are found here Most of earths weather is controlled here
What are some features of the stratosphere
the air in this layer is thin and dry Aircrafts fly here
What are features of the mesosphere
This layer protects earth from meteors
What are features of the Thermosphere
satelites orbit in this layer Auroras take place in this layer
What are features of the Exosphere
Least dense atmospheric layer Merges with space Satelites orbit in this layer
What are some features of the ozone layer
Made of three oxygen atoms Absorbs most harmful UV from the sun Ozone is found in the troposphere and stratosphere
What is UV radiation
Is radiation emitted by the sun UV-A UV-B UV-C
What is UV-A
Ozone is transparent to this UV it reaches the Earth
What is UV-B
Partly blocked by ozone layer but is concentrated and strong
What is UV-C
Highest energy UV radiation but entirely blocked by oxygen and ozone
