How do "de-icing" methods differ from "anti-icing" methods?

• A. De-icing removes existing ice; anti-icing prevents ice formation
• B. De-icing is more cost-effective than anti-icing
• C. De-icing is used before storms; anti-icing is used after
• D. De-icing uses sand; anti-icing uses salt

Answer: (A)

De-icing methods are specifically designed to remove ice that has already formed on surfaces, such as roads, sidewalks, and aircraft wings, ensuring safety and functionality after the ice has developed. These methods typically involve the application of chemical agents that help melt the ice and make it easier to manage, clearing away any dangerous accumulations. On the other hand, anti-icing methods are implemented with the intention of preventing ice from forming in the first place. This proactive approach often involves applying materials that create a barrier against ice formation, which is particularly useful before an anticipated snow or ice event. By using these methods, operators can minimize the accumulation of ice and make subsequent clearing more effective. The distinction between these two approaches highlights the timing and purpose of each. De-icing is reactive, addressing ice after it has formed, while anti-icing is preventative, aiming to stop ice from developing at all. This understanding of their differing objectives is critical for effective winter management and safety.
