Prompt Clouds appear white because…

Choices (one per line; prefix correct one with * ) * Non-selective scattering — water droplets ≫ wavelength, all wavelengths scattered equally Rayleigh scattering favors blue Mie scattering affects only IR Clouds absorb all visible light

Plain English answer (default view) — what you'd actually write on the test

🔬 Technical version / model bullets (revealed on click) — one bullet per line B, G, R scattered in equal proportion → white.

💡 Mnemonic / memory aid (shown on hover) 'Non-selective' literally means ALL colors treated equally → white. Big particles (droplets) = non-selective. Tiny particles (molecules) = Rayleigh = blue sky.
