Question

At the upper level of the atmosphere (stratosphere), ozone shields the surface of the earth from the __________ radiation of the Sun.

Answer 1

Ozone

1. A naturally occurring layer of ozone at stratosphere absorbs potentially damaging ultraviolet radiations from sun.
2. Therefore, this ozone layer is important for life forms on the earth but the amount of ozone in the stratosphere has dropped sharply in the recent past.

Final answer: At the upper level of the atmosphere (stratosphere), ozone shields the surface of the earth from the ultraviolet radiation of the Sun.
