Which term refers to frost, the deposition of water vapor onto surfaces as ice?

Explanation:
Frost is the term for the visible ice crystals that form on surfaces when water vapor deposits directly as solid ice. The process by which this happens is called deposition—the gas-to-solid phase change. So frost names the actual frozen deposit you see, while deposition describes how that deposit forms. Condensation would involve liquid water forming from vapor, sublimation is solid turning into gas, and neither describes the icy coating you call frost.
