WebDec 17, 2024 · In the strictest sense, albedo—or whiteness —is defined as the proportion of light reflected from a surface. Seen from space, Earth is a patchwork of darkness and light, from bright white ice caps and clouds to super-dark lava beds and everything in between. On average, though, about 30% of the sunlight that falls on Earth bounces back to space. WebAlbedo is the fraction of incoming sunlight that our planet reflects back to space. If Earth was covered in ice like a giant snowball, its albedo would be about 0.84, meaning it would reflect most (84 percent) of the sunlight … patient past due balance letter
