Select ALL correct properties of a direct Mercator chart.
Answer
It is conformal, Rhumb lines appear straight, Great circles generally appear curved
Explanation
Mercator projection preserves local angles, making it conformal, and depicts rhumb lines as straight lines. Great circles generally curve on the chart, and the projection does not preserve area. **Key takeaway:** Mercator supports constant-bearing plotting, not equal-area comparison.\n\n**Glossary:** **Conformal**: preserving local angles; **rhumb line**: constant-bearing route.
