Answer 1

QUESTION:

Give Scientific reasons:

Ozone layer is a protective shell of the earth.

ANSWER:

• The ozone layer acts as a protective layer for life on the earth because it absorbs harmful ultraviolet radiation of the sun.
• These radiations, if reach the Earth's surface, can cause skin cancer.
• The ozone layer of the atmosphere protects life on earth by filtering out some of the harmful ultraviolet radiation from the sun.
• Thinning of this layer therefore poses a threat.
• Thinning is a result of the release into the atmosphere of substances which destroy ozone.
