where is the protective ozone layer located

The protective ozone layer is located high above us in the stratosphere , mostly between about 15 and 35 kilometers (roughly 9–22 miles) above Earth’s surface.

Quick Scoop: Where It Sits

• The ozone layer is not at ground level; it forms a thin “shield” in the stratosphere, the second layer of the atmosphere above the troposphere.

• Most of Earth’s ozone (about 90%) is concentrated in this band, typically from around 15 km up to about 35–40 km, depending on latitude and season.

• A common textbook way to say it: the protective ozone layer is in the lower stratosphere, roughly 15–35 km above the surface, where it absorbs most of the Sun’s harmful ultraviolet (UV) radiation.

Why That Location Matters

• At those heights, ozone molecules can form and persist long enough to build up, creating an effective UV “sunscreen” for the planet.

• If you could somehow squish all that high-altitude ozone down to sea-level pressure, the entire ozone layer would only be a few millimeters thick—thin but crucial for life.

TL;DR: The protective ozone layer is a thin band of ozone gas in the stratosphere, mainly between about 15 and 35 km above Earth’s surface, where it blocks most harmful UV radiation.
