Which of the following are effects of melting sea ice? Select the two correct answers. (1 point)
The exposed water reflects back more sunlight than did the ice.

Final answer:

Melting sea ice leads to a significant decrease in albedo, causing the exposed water to absorb more solar energy, subsequently increasing Arctic temperatures.


Explanation:

When sea ice melts, the albedo of the area affected changes dramatically from around 80% down to less than 10%. This change causes the exposed water to absorb more solar energy than ice did. As a result, the Arctic temperatures increase due to more heat being absorbed by the open water.
