🔍 Key Concepts

• Coast Pilot and nautical charts descriptions of named reefs • Differences between shoals, reefs, and islets • How tide levels (low water springs vs all stages of tide) affect what is visible

💭 Think About

• Think about what the name 'Branford Reef' suggests about its general nature and whether it is likely to be dry, awash, or always submerged • Consider which options describe features that would normally be called an 'islet' versus a 'reef' on official charts • Ask yourself which descriptions would require special chart notes or symbols for rocks, drying heights, or lights

✅ Before You Answer

• Check which options describe something that is always above water, sometimes above water, or always submerged • Verify which descriptions would typically include a light or other aid to navigation on charts for a coastal reef • Eliminate any choice that conflicts with how a reef off the U.S. East Coast near Branford, Connecticut, is commonly charted and described
