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).
<span>The equator is 0 degree latitude. This imaginary line, which runs through parts of South America, Africa, and Asia, is officially the halfway point between the North Pole and the South Pole.</span>
<span>The prime meridian is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica.</span>
By using the equator and prime meridian, we can divide the world into four hemispheres, north, south, east, and west. For instance, the United States is in the Western Hemisphere (because it is west of the prime meridian) and also in the Northern Hemisphere (because it is north of the equator).
<span>These lines are merely for the identification of where things are on a map or a globe.</span>
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. ... Scientists are studying exactly how ice caps disappear.
