🔍 Key Concepts

• compass rose information on a nautical chart • difference between variation and deviation • how changes over time (like yearly changes) are shown on charts

💭 Think About

• Look at what information is printed around the outer and inner circles of a compass rose on a chart—what two reference directions are being related? • Ask yourself: does the compass rose show something specific to your ship’s compass, or something about the Earth’s magnetic field in that chart area? • Consider which choice is normally written as a small note near the rose (with a year and a rate of change), instead of being a separate label on the rose itself.

✅ Before You Answer

• Be clear on the difference between ship’s compass error sources (like deviation) and geographical differences (like variation). • Recall that the compass rose has an outer ring and an inner ring—what does each ring represent? • Verify which item is usually shown as a numerical value with a direction (E or W) on the rose itself, not just in a nearby note.
