GENERAL KNOWLEDGE

Detailed explanation-1: -The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth’s surface, in the stratosphere.

Detailed explanation-2: -The ozone layer is located in the stratosphere around 15-30 km above to the earth’s surface.

Detailed explanation-3: -About 10% of atmospheric ozone is in the troposphere, the region closest to Earth (from the surface to about 10–16 kilometers (6–10 miles)). The remaining ozone (about 90%) resides in the stratosphere between the top of the troposphere and about 50 kilometers (31 miles) altitude.

Detailed explanation-4: -The natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it. Ozone is created when the kind of oxygen we breathe-O2-is split apart by sunlight into single oxygen atoms.
