Why has the temperature of the Arctic Ocean changed during the last 40 years? (1 point)

Question

Less snow falls in the Arctic now than 40 years ago.
More sunlight now reaches Earth than in the past.
Sea ice has melted, allowing more sunlight to hit the ocean.
Sea ice has produced more salt, causing the cold ocean water to sink.

Answer 1

The correct answer is: Sea ice has melted, allowing more sunlight to hit the ocean.

This melting of sea ice reduces the reflective (albedo) effect that ice has, allowing more solar energy to be absorbed by the ocean, which contributes to the warming of the Arctic Ocean over the past 40 years.
