Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the phenomenon?Polar amplification
2. What is the location?Earth's polar regions (Arctic and Antarctic)
3. Why do the poles get warmer faster than other places?Because of feedbacks like ice turning into darker water or land, which absorbs more heat, and the air near the surface stays warm.
4. How does the ice‑albedo feedback work?Snow and ice reflect sunlight, but when they melt, darker surfaces show, they absorb more sunlight, making the area even warmer.

Polar amplification: The phenomenon whereby polar regions experience a greater magnitude of temperature change compared to the global average.
Radiative balance: The equilibrium between incoming solar radiation and outgoing infrared radiation that determines Earth's temperature.
Ice-albedo feedback: A positive feedback loop where melting ice reduces Earth's reflectivity, leading to increased absorption of solar radiation and further warming.
Lapse rate feedback: A feedback mechanism related to how temperature changes with altitude, which can enhance polar warming.
