The correct answer is
Stratosphere

Ozone Concentration in Atmosphere

The majority of atmospheric ozone is found concentrated in a specific layer of Earth's atmosphere.

Ozone Layer Location

  • Ozone (O3) is a molecule crucial for absorbing harmful ultraviolet (UV) radiation from the sun.
  • While ozone is present in small amounts throughout the atmosphere, its highest concentration occurs in the Stratosphere.
  • This region is commonly referred to as the "ozone layer".

Atmospheric Layers Overview

The atmosphere is divided into several layers based on temperature trends. These include the Troposphere (lowest layer), Stratosphere, Mesosphere, Thermosphere, and Exosphere. The ozone layer is predominantly situated within the lower to middle portion of the Stratosphere, typically between 15 to 35 kilometers (9 to 22 miles) above the Earth's surface.

Therefore, the Stratosphere is the atmospheric layer where most ozone is concentrated.
