6th question explanation [#permalink]
6th question it says about reductive system in the beginning of the second paragraph that that its amount will be lower in the stratosphere than on the Earth. Could someone explain why it is not B? It cearly says more about reductive system than about interaction which it barely touches.

Hi Elmar91,

Quote:
(B) a reductive system


Answer to 6th question can be inferred from lines:
"In the stratosphere, ozone is continuously being made and destroyed by natural processes. During the day the Sun breaks down some of the oxygen molecules to single oxygen atoms, and these reacting with the oxygen molecules that have not been dissociated, form ozone. However, the sunlight also breaks down ozone by converting some of it back to normal oxygen. In addition naturally occurring nitrogen oxides enter into the cycle and speed the breakdown reactions. The amount of ozone present at any one time is the balance between the processes that create it and those that destroy it.".

The above highlighted lines imply that the process that determines the amount of ozone in the stratosphere is an based on interactive relationship. Nothing about "reductive system" can be inferred from the passage. What's mentioned at the start of the 3rd para is: "The amount of ozone near the Earth is only a small percent of the amount in the stratosphere", but we cannot infer that is a reductive system, but from the 1st and 2nd para, we can definitely that the amount of ozone breaking and forming is based on an interactive relationship.


Hope This Helps.
Thanks.
