Question

What are the difference between ozone in the stratosphere and ground-level ozone?

Answer 1

Ground-level ozone is an air pollutant and is harmful to animals as it produces respiratory problems whereas stratospheric ozone protects us from the harmful ultra violet(UV)radiation of the sunlight by absorbing it.

In the stratosphere,some oxygen molecules absorb energy from the sun's UV rays and split to form single oxygen atoms

.These atoms combine with the remaining oxygen to form ozone which is effective in absorbing UV rays.

At ground level ozone is produced when oxygen is exposed to high energy(usually electrical or ultra-violet)

.Further action of sunlight on primary emissions mainly from automobiles also produce ozone at ground level.

Answer 2

Explanation:

Unlike stratospheric ozone, which forms naturally in the upper atmosphere and protects us from the sun's harmful ultraviolet rays, ground-level (or tropospheric) ozone is created through the interactions of man-made (and natural) emissions of volatile organic compounds and nitrogen oxides in the presence of heat and
