When meridians are straightened out?

When meridians are straightened out, it typically refers to the concept of transforming the curved lines of longitude on a globe into straight lines, often for mapping purposes. This process can distort the shapes and areas of landmasses, as seen in various map projections like the Mercator projection. Straightening meridians helps simplify navigation and improves visibility of certain regions, but it can also lead to misconceptions about the true scale and distance between places. Thus, while useful for practical applications, this alteration comes with trade-offs in geographic accuracy.
