Answer:
Option (C)
Explanation:
CO₂ is one of the main green house gases on earth. A small increase in its concentration can lead to significant changes on earth. When the incoming solar radiations are incident on the earth's surface, some of the energy is absorbed by the atmosphere and the earth's surface. And some of the energy from the land surface after absorption is released into the atmosphere in the form of infrared radiations. The escaping of these radiations from earth is directly dependent on the concentration of CO₂. An increase in the amount of CO₂ will not allow these IR radiations to be removed, and this will result in the global rising of the temperature, leading to catastrophic changes.
Thus, the correct answer is option (C).

Seismometers are tools which measure motion in the ground including seismic waves generated by earthquakes, volcanoes, and other activities which might create seismic waves. Seismometers measure any movement of seismic activity in the earth and today this is done by electronic means whereby the machine measures any changes in seismic activity in the surrounding areas of the seismometer. The first seismometer is believed to have been invented by Zhang Heng of China's Han Dynasty in 132 AD.
