Question
Ozone gas is heavier than air. Why does ozone layer not settle down near the earth?
✓
Answer
Ozone layer is formed at an altitude of 25-30km from earth's surface by action of U.V. light on oxygen.
At this altitude force of gravitation is negligible that is why ozone does not settle near the earth.
At this altitude force of gravitation is negligible that is why ozone does not settle near the earth.
