Sea ice helps determine Earth's climate. According to this, what percentage of the sunlight falling on sea ice is reflected back into space?
 

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 80%

  • Sea ice has a high albedo (reflectivity), meaning it reflects a large portion of incoming sunlight.

  • Around 80% of the sunlight falling on sea ice is reflected back into space.

  • This helps in regulating Earth’s temperature and delaying global warming.

  • When sea ice melts, darker ocean water absorbs more heat, accelerating climate change.

  • Hence, sea ice plays a critical role in the Earth’s energy balance.
