A The dark ocean reflects more sunlight, cooling the planet down.
B The dark ocean absorbs more solar radiation, accelerating further warming and melting.
C The dark ocean water prevents clouds from forming, reducing rainfall.
D The dark ocean increases the Earth's overall albedo, stabilizing the climate.

Show answer and explanation

Answer: B. The dark ocean absorbs more solar radiation, accelerating further warming and melting.

Correct Answer: B
Explanation: Melting ice lowers the Earth's albedo (reflectivity), causing the dark ocean to absorb more heat, which triggers a dangerous loop of even more melting.
