Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
The statement, “An arid or
semi-arid climate occurs where precipitation is greater than potential evaporation”,
is false. A semi-arid climate occurs where the recipitation is below the
potential evaporation. Regions that experiences arid climate receives less than
10 inches of rainfall in an entire year.
Deforestation, that would be clearing the land leading to desertification
