The Suez Canal, like many other large-scale engineering projects, appears flat when viewed over relatively short distances, such as the 120 miles of the canal. This perception of flatness is due to several factors:
1. **Earth’s Curvature**: The Earth's curvature is subtle at such short distances. While the Earth is approximately 24,901 miles in circumference, the curvature becomes noticeable only at greater distances. For example, the
