Which description correctly defines ice accretion?

• A. The buildup of ice on exterior surfaces due to icing
• B. Ice crystals forming in clouds
• C. Ice formed on seabed
• D. Ice that breaks off from hull

Answer: (A)

Ice accretion is the buildup of ice on exterior surfaces due to icing. It happens when exposed surfaces encounter freezing temperatures and moisture, causing supercooled water droplets or moisture in the air to freeze on contact and form layers of ice. This is a surface phenomenon that increases weight, alters shape, and can affect performance and safety. In contrast, ice crystals forming in clouds describe ice suspended in the air, not accumulated on a surface. Ice formed on the seabed refers to ice in the water environment itself, not ice accumulating on a vessel. Ice that breaks off from the hull describes detachment or shedding, not the process of accumulation.
