🔍 Key Concepts

• Snow and cloud conditions that affect visibility • How shadows and horizon cues help with depth perception at sea or in polar regions • Differences between optical phenomena over ice versus open water

💭 Think About

• Which option describes a condition where everything looks the same color/brightness and you lose all sense of horizon or distance? • Which terms in the choices are associated with light reflection from ice versus light reflection from open water? • Think about which phenomenon pilots and mariners especially fear because it makes it very hard to judge surface features or obstacles.

✅ Before You Answer

• Identify which term is commonly linked with loss of depth perception and horizon in snowy or icy environments • Match each wrong-sounding option with what it actually means (for example, reflection from ice vs reflection from water vs upper-atmosphere light). • Confirm that the correct term is the one that would make it hardest to see relief, shadows, and the true position of the surface.
