The ozone layer is present in the atmosphere approximately ____?

1. 5 to 10 Km high up the ground
2. 16 to 20 Km high up the ground
3. 12 to 50 Km high up the ground
4. 16 to 50 Km high up the ground

The ozone layer is not a thin, concentrated layer but a region within the stratosphere where ozone concentrations are relatively high. This region spans from approximately 15 to 35 kilometers (9 to 22 miles) above Earth’s surface, with maximum concentration typically found between 20 and 25 km. The option “12 to 50 Km” provides the most accurate and encompassing range.
