Q: The layer where the decrease in temperature with increasing altitude is totally absent is
  • A. Troposphere
  • B. lonosphere
  • C. Stratosphere
  • D. Mesosphere
Correct Answer: Option C - The stratosphere defines a layer in which temperatures rises with increasing altitude. At the top of the stratosphere the thin air may attain temperatures close to 0⁰C. This rise in temperature is caused by the absorption of Ultraviolet (UV) radiation from the sun by the ozone layer, such a temperature Profile creates very stable atmospheric conditions. Consequently, the stratosphere is almost completely free of clouds or other forms of weather.
