Ozone layer, which absorbs the ultra-violet radiation, is found in which one of the following layers of the atmosphere ?

The ozone layer is primarily located in the stratosphere, extending from approximately 10 km to 50 km above the Earth's surface [7]. While ozone exists in trace amounts throughout the atmosphere, about 90% of it is concentrated in the stratosphere [3]. This layer plays a vital role in safeguarding life by absorbing and filtering out harmful ultraviolet (UV) radiation from the sun, particularly UV-B and UV-C [6]. The absorption of this radiation by ozone molecules leads to a temperature increase with altitude, a phenomenon known as a negative lapse rate, which distinguishes the stratosphere from the troposphere below it [4]. The highest concentration of ozone, often referred to as the ozone layer or ozonosphere, typically occurs between 15 km and 35 km [5]. In contrast, the troposphere contains 'bad' ozone formed by pollutants, while the mesosphere and ionosphere lie at much higher altitudes with different physical properties [3].
