The stratosphere is the atmospheric region located directly above the troposphere and below the mesosphere. It starts at the tropopause and extends upward to an altitude of about fifty kilometers. Unlike the layer below it, the stratosphere is characterized by a temperature increase with height, primarily due to the absorption of solar ultraviolet radiation by the vital ozone layer. ANSWER: (B) Regions located above the troposphere
Which part of the atmosphere is the stratosphere? (A) Lower region of the atmosphere (B) Regions located above the troposphere (C) Central region of the atmosphere (D) Upper region of the atmosphere

Positioned between the troposphere and the mesosphere, the stratosphere is the second major layer of Earth’s atmosphere. It begins at an altitude of roughly twelve kilometers and reaches up to fifty kilometers. This layer is distinct because it contains the ozone layer, which plays a crucial role in absorbing harmful ultraviolet rays. This absorption causes the air in the stratosphere to warm up as you go higher, reversing the cooling trend found in the troposphere. Because it is largely free of weather-producing water vapor, the stratosphere remains stable and clear, serving as a distinct atmospheric boundary.
