Frequent tropical storms and melting of polar ice are the effects of which of the following options?
Answer & explanation
Correct answer: option 2
The correct answer is option 2: Global warming
Global warming refers to gradual increase in the average temperature of planet. Some of the effects of global warming are:
- Melting of polar ice which results in rise in the sea level and coastal flooding
- Disruption of drinking water supplies which are dependent on snow melts
- Frequent tropical storms due to change in the temperature
- Increase in the incidence of tropical diseases
Note : Global warming leads to a rise in Earth’s temperature. This increase in temperature causes polar ice caps and glaciers to melt and also makes oceans warmer, which increases the frequency and intensity of tropical storms. Deforestation, on the other hand, is a cause of global warming, not the direct effect responsible for these changes. Therefore, the correct option is Global warming, not “Both 2 and 3.”
