Common Mistakes: A common misunderstanding is that melting ice caps only affect sea levels, without considering the impact on Earth's albedo and the resulting feedback loop that can accelerate warming.

Explanations: The melting of polar ice caps reduces the Earth's albedo because ice and snow reflect more sunlight than the darker surfaces of land or water. As more ice melts, less sunlight is reflected, leading to increased absorption of solar radiation and further warming, which in turn causes more ice to melt. This positive feedback loop contributes to the overall decrease in Earth's albedo.

Option Analysis:

Option A: Correct. The melting of polar ice caps decreases Earth's albedo because the exposed surfaces absorb more sunlight than the reflective ice and snow.
Option B: Incorrect. This option suggests that the melting of polar ice caps does not contribute to a decrease in Earth's albedo, which is not accurate.

Mnemonic: Ice melts, Earth gets darker.
