Question

High concentration of greenhouse gases has resulted in maximum rise of atmospheric temperature in
A) Tropic region
B) Middle latitude
C) Polar region
D) Temperate region

Answer 1

Hint:As a major adverse effect of greenhouse effect, the ice glaciers melt over time. The water bodies like oceans and the land becomes more exposed, leading to certain conditions.

Complete answer:
Greenhouse effect refers to the trapping of heat close to the surface of Earth, eventually warming it, by the greenhouse gases. A balanced concentration of greenhouse does no harm to our Earth. But when it exceeds, that is when it becomes a real threat, hence trapping more heat, causing the rise in global temperature.
So now let us look into each of the options given to us, and get into the right option:-
>Option A: Tropic region- In the equatorial region, there is not much effect as in other regions. Therefore, this is the incorrect option.
>Option B: Middle latitude- Even though there is a rise in temperature, it is not the maximum. Therefore, this is the incorrect option.
>Option C: Polar region- There is maximum effects and temperature rise in this region, and hence is the most affected. Due to the melting of ice caps, there is a significant rise in the sea levels. There is an approximate rise of eight degrees Fahrenheit in this region. Therefore, this is the correct option.
>Option D: Temperate region- As we have already found the right option, this is the incorrect option.

Thus, the correct answer is option (C) Polar region.

Note:According to estimates, the famous Kilimanjaro is said to have melted more than 80 percent since 1912.
>Due to the rise in temperature and melting of ice, the rise in average global sea level ranges from four and eight inches in the past hundred years.
