<em><u>The troposphere is the lowest layer of the atmosphere, which is most influenced by human activities. (d)
</u></em>
Further Explanations:
Atmosphere of the Earth is the layer of gases covering the earth, held by the gravitational force of the Earth. The atmosphere is characterized by high pressure and low temperature. As we go up higher and higher temperature decreases. The atmosphere comprises of many gases such as nitrogen (78%), carbon dioxide (0.04%), Oxygen (21%), Argon (0.09%) and the rest other gases among which oxygen is used by the living organisms on earth.
The earth's atmosphere is differentiated into five layers based upon its temperature namely exosphere, the troposphere, the thermosphere, the stratosphere, and the mesosphere with troposphere as its lowest layer and the most affected by exosphere, the troposphere, the thermosphere, the stratosphere, and the mesosphere. The width of the layer varies with the landforms and the time of the day. Human activities like industrial and vehicle emission are affecting the troposphere. Other several human activities also affect the troposphere and lead to the depletion of the Ozone layer that had resulted in global warming.
