उत्तर
Mesosphere
Explanation:
The mesosphere lies above the stratosphere and extends up to around 85 km altitude. It has the coldest temperatures in the atmosphere, dropping as low as −90°C. This temperature decrease in the mesosphere is due to increasing altitude and decreasing absorption of solar radiation. The mesosphere is colder than the troposphere, stratosphere, and thermosphere, making it the coldest atmospheric layer.
