Why has the temperature of the Arctic Ocean changed during the last 40 years?(1 point) Responses Sea ice has produced more salt, causing the cold ocean water to sink. Sea ice has produced more salt, causing the cold ocean water to sink. Less snow falls in the Arctic now than 40 years ago. Less snow falls in the Arctic now than 40 years ago. More sunlight now reaches Earth than in the past. More sunlight now reaches Earth than in the past. Sea ice has melted, allowing more sunlight to hit the ocean.

Answer 1

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

This melting of sea ice reduces the albedo effect (the reflection of sunlight), allowing more solar energy to be absorbed by the ocean, which contributes to the increase in temperature.
