Which layer of the atmosphere contains the ozone layer and minimal water/clouds?

The stratosphere is the layer of the atmosphere that contains the ozone layer, which is crucial for absorbing the majority of the sun's harmful ultraviolet radiation. This layer extends from about 10 to 50 kilometers above the Earth's surface. One of the defining characteristics of the stratosphere is its relative stability compared to the troposphere, leading to a minimal presence of water vapor and clouds. The stability results in fewer weather phenomena occurring in this layer, which is why clouds are not commonly found here.

The ozone layer within the stratosphere is vital for protecting living organisms from UV radiation, while the lack of significant water vapor contributes to the unique conditions of this layer, such as temperature increases with altitude, a phenomenon known as temperature inversion, which helps to maintain its structure. Understanding the dynamics of the stratosphere is essential for grasping broader concepts in atmospheric science and environmental studies.
