Ozone depletion consists of two related events observed since the late s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere the ozone layer , and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events. The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants , solvents , propellants and foam- blowing agents chlorofluorocarbons CFCs , HCFCs, halons , referred to as ozone-depleting substances ODS. These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle.

In every competitive exam, Odd Man Out type questions are very common. In odd man out problems all the items given in the question except one follow a certain pattern or a group. That means out of the all given elements, one will not fall into the group due to some difference in the property. That is the odd element. Hence, it is the odd one. From the above, the second one is the feminine of the first one except the first pair. So the answer will be a.

In this type, a group of messed letters consisting 3 letters are kept together. The pattern in which they are grouped is to be analysed and we have to find which group out of this have the same pattern or relationship between the letters. In this type, different items which belong to common properties like places, parts of speech, professions, etc. But moon is a satellite. So moon will be the right answer.

Number classification means a group of numbers which follows the same pattern. In this case we will see that there are numbers given in question from which we have to find the odd one. The numbers may belong to a particular set i.

One choice will not follow the rule and that will be our answer. The following steps are required to analyse the question. Try remaining Mathematical Possibilities like tables, divisibility rules. If you are not able to find any link among given options, try to catch out correlation among the digits of every number it encounters. Here, choice d will be the answer because 15 is not a prime number but all others are prime numbers.

Emissions were increasing rapidly until the s. Since then the world has achieved rapid progress: the near-elimination of ozone-depleting substances and the trend towards recovery of the ozone layer are arguably among the most successful international environmental collaborations to date.

We've made some changes to EPA. Scientific Assessment of Ozone Depletion: Twenty Questions and Answers about the Ozone Layer. Addressing Ozone Layer Depletion.
