There are five concentric layers within the atmosphere which is differentiated on the basis of temperature. The atmospheric layer which lies close to the earth’s surface in which human being along with other organisms live is called troposphere. The rate at which air temperature in the troposphere gradually decreases with height is about _____________ °C/km?
Correct answer: C
Explanation
The temperature in the troposphere generally decreases with altitude at a rate known as the lapse rate. This standard rate is approximately 6.5 °C/km.
