"The ozone hole is steadily repairing itself".
A.What is the reason behind this?
B. What do you mean by ozone hole?
C. What are the reasons for formation of ozone hole?
Answers
Answer:
scientists got sufficient data to confidently reveal proof that the ozone layer was indeed on a path to recovery. The 2016 study, which tracked the evolution of the size of the ozone hole over Antarctica, observed that stratospheric ozone concentrations were continuing to increase and that the size of the Antarctic ozone hole had declined by half the size of the continental U.S. between 2000 and 2015. The authors of the study also noted that they expected the ozone layer to fully heal sometime between 2040 and 2070.
Explanation:
a region of marked thinning of the ozone layer in high latitudes, chiefly in winter, attributed to the chemical action of CFCs and other atmospheric pollutants. The resulting increase in ultraviolet light at ground level gives rise to an increased risk of skin cancer.
Answer:
- formation of oxygen
- breakage of layer in ozone due to global warming
- CO2 and some green house gases
