Ozone hole refers to
1 Reduction in the thickness of ozone layer in troposphere
2 Hole in ozone layer in stratosphere
3 Increased concentration of ozone
4 Reduction in the thickness of ozone layer in stratosphere
Explanation:
Ozone layer is present on stratosphere of atmosphere. Ozone layer is destroyed by release of many substances like CFC. Hole in ozone layer allows UV rays to reach earth by which it causes skin cancer.
