What is the term for the process where ice turns directly into water vapor?

• A. Condensation
• B. Evaporation
• C. Sublimation
• D. Precipitation

Answer: (C)

The term describing the process where ice turns directly into water vapor is sublimation. This process occurs when a solid transitions to a gas without first becoming a liquid. An example of sublimation can be observed with dry ice (solid carbon dioxide), which sublimates at room temperature, transforming directly into gas. Understanding sublimation is important in various fields, such as meteorology and environmental science, as it contributes to the water cycle, particularly in cold regions where ice (such as snow or glaciers) can directly atmospheric moisture without melting into liquid water first.
