Detailed explanation-1: -90% of the planet’s ozone is in the “ozone layer” which exists in the lower level (20-25 kilometres above sea level) of the stratosphere. The stratosphere is the region of the atmosphere which exists between 10 and 50 kilometres above the surface of the earth.

Detailed explanation-2: -The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB.

Detailed explanation-3: -Ozone occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
