Question

The effects of global warming are:
1. The sea level may rise.
2. It will prevent the stirring up of the oceans.
3. Fish population will migrate towards the Tropics.
4. Precipitation will be frequent.
Select the correct answer from the codes given below.

• A. 1, 2, 3 and 4
• B. 1 and 3
• C. 1 and 4
• D. 1, 2 and 4

Answer 1

The correct option is C 1 and 4

Global warming refers to heating up of earth's atmospheric due to increased absorption of terrestrial radiation by greenhouse gases due to increase in their concentration. It may lead to sea level rise and rise in temperature may increase the capacity of air to hold moisture which in turn may lead to increased precipitation.

It is uncertain whether global warming can prevent the stirring up of oceans, although it may have a significant impact on the circulation pattern. Moreover, due to higher temperature in the tropics, fishes may move towards the poles in search of cooler waters instead of the other way around.
