🔍 Key Concepts

• Polar atmospheric and sea conditions (very cold air over relatively warmer water) • Optical phenomena such as mirages and false horizons in high latitudes • Typical precipitation patterns in polar climate zones

💭 Think About

• Which of these phenomena are specifically associated with very cold air moving over warmer open water? • Which options relate to how objects appear to your eye (visual/optical effects) rather than to weather or precipitation? • Think about what is common and expected in polar regions versus what is relatively rare or limited in extent.

✅ Before You Answer

• Identify which choices are optical phenomena (related to how you see the horizon or distant objects). • Identify which choice is primarily a precipitation pattern rather than an optical or sea-surface effect. • Consider which phenomenon is least characteristic or widespread in polar regions, even though it may occur there at times.
