Question

Why is ozone layer called ozone umbrella/shield? What would be the effects on widening of ozone hole?

Answer 1

Ozone layer refers to the region of the Earth's atmosphere, which has a relatively higher concentration of ozone. This layer is also called ozone layer/umbrella because it acts as a shield and prevents the propagation of harmful ultraviolet radiation to the Earth's surface.

The widening of the ozone hole can have following consequences:
1. The chances of skin cancer will be increased.
2. The overall crop yield will be profoundly decreased.
3. The populations of zooplanktons and phytoplanktons will be severely reduced.
