Question

1. why is the albedo effect crucial in polar regions?

a. it helps regulate temperatures by reflecting sunlight
b. it supports photosynthesis in plants
c. it decreases carbon levels in the air
d. it absorbs heat to increase polar warmth

Explanation:

The Albedo effect refers to the reflection of solar radiation. In polar regions, ice and snow have high albedo, reflecting sunlight to regulate temperature. Option a matches this. Option b is incorrect as polar regions have limited plants for photosynthesis. Option c is wrong as albedo doesn't directly affect carbon levels. Option d is incorrect because high albedo reflects, not absorbs, heat.

Answer:

a. It helps regulate temperatures by reflecting sunlight
