Question

There is a possibility of melting of polar ice caps and increase in the level of sea water due to:
A. Depletion of ozone layer
B. Greenhouse effect
C. Acid rain
D. All of these

Answer 1

Hint: The melting of ice in the polar region is because of the elevated temperature of our environment which is increasing from year to year due to various human activities. The increasing temperature melting occurs and is affecting the natural habitat of certain polar animals prevailing there and is leading to their extinction from nature.

Complete step by step answer: The temperature of the atmosphere is increasing due to the greenhouse effect. The greenhouse effect is the trapping of solar energy in the environment which is not able to leave the atmosphere leading to elevated temperature of the atmosphere. The trapping of the solar rays is due to increased carbon dioxide gas content in the atmosphere due to various human activities such as cutting down of trees, increased burning off fuel, pollution, excessive use of electronic devices such as air conditioners. These activities produce enormous amounts of carbon dioxide which are responsible for the elevated temperature and the melting of the polar caps.
The melting of ice at Polar Regions is increasing the sea water level which is creating the risk of flood in the coastal areas and the areas which are near are seas or the drowning or certain islands. The major effect is seen in the polar animals which need ice for their survival but due to melting of ice they are at the verge of being extinct. Example: polar bear.
So, the correct answer is “Option B”.

Note: The effect of this greenhouse effect can be decreased with the reduced use of automobiles and planting more trees, and by avoiding the methods which will produce more carbon dioxide gas in nature, such as the smoke coming out of industries which can be filtered into harmless particles.
