43. Which describes a Mercator chart?
Answer
Scale increases with latitude; great circles curved; rhumb lines straight
Explanation
Mercator projection preserves angles and represents rhumb lines as straight, while scale increases toward higher latitudes and great circles are generally curved. **Key takeaway:** A straight Mercator line is a constant-bearing route. **Glossary:** Projection: method of representing Earth on a flat chart.
