(a) Ozone hole is a hole formed in stratosphere
from which ozone oozes out.
(b) Ozone hole is a hole formed in the
troposphere from which ozone oozes out.
(c) Ozone hole is thinning of ozone layer of
stratosphere at some places.
(d) Ozone hole means vanishing of ozone layer
around the earth completely.

Answer 1

Answer:

(c). is the answer.......

Answer 2

(c) Ozone hole is thinning of ozone layer of stratosphere at some places.

Explanation:

The ozone layer or ozonosphere contains relatively high concentrations of ozone (O3) molecules. Approximately 90% of atmospheric ozone occurs in the stratosphere, which extends from 10-18 km to 50 km above the earth's surface. The ozone layer protects us from the harmful effects of the ultraviolet radiations of the sun by blocking these UV rays. Without the ozone layer, these UV rays would reach the Earth's surface and cause injury and may even kill most living things. The thinning of ozone layer of stratosphere at some places is called ozone depletion.

Option C is the answer.
