Why has the temperature of the Arctic Ocean changed during the last 40 years?(1 point) Responses 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. 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 response is: Sea ice has melted, allowing more sunlight to hit the ocean.

Over the past 40 years, the Arctic has experienced significant warming due to climate change, resulting in the melting of sea ice. This loss of ice decreases the albedo effect (the reflectivity of the Earth's surface), allowing more sunlight to be absorbed by the ocean, which further increases the temperature of the Arctic Ocean.
