The correct answer is (d), Antarctica.
The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth’s atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometers (12 to 19 mi) above Earth, although its thickness varies seasonally and geographically.
The ozone layer is important because it protects life on Earth from harmful ultraviolet radiation. Ultraviolet radiation can cause skin cancer and other health problems, as well as damage plants and animals.
The ozone layer is being depleted by human activities, mainly the release of chlorofluorocarbons (CFCs) into the atmosphere. CFCs are chemicals that were once widely used in refrigerators, air conditioners, and other products. When CFCs reach the stratosphere, they break down and release chlorine atoms. These chlorine atoms react with ozone molecules, destroying them.
The depletion of the ozone layer is a serious problem, but it is one that we can solve. We can reduce our use of CFCs and other ozone-depleting substances. We can also support policies that promote the use of ozone-friendly products and technologies. By taking these steps, we can help to protect the ozone layer and the life on Earth that it protects.
The other options are incorrect because they are not places where the ozone layer is depleted the most. India, Africa, and Europe are all places where the ozone layer is depleted, but not as much as Antarctica.
