Question

Which most likely happened if the Earth’s average global temperature changed to 16°C?

Answer 1

I would think that the answer would be the first one, because of the ice melt from the glaciers and other sources, the water would reflect the solar energy/radiation a lot better than the soil, which would absorb the solar energy. I'm not entirely sure if this is right, but I think it might be correct.

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

Temperature of Earth increases due to the radiations from the Sun which are basically absorbed by the Earth.

Whereas when less radiation is absorbed then it means more heat is removed from the surface of Earth.

When more number of radiations are radiated back by the Earth into the space then there will be decrease in the temperature of Earth.

Hence, we can conclude that if the Earth’s average global temperature changed to 16°C then more energy was reflected back to space.
