ROUND 1
Greenland — 2,670 km
Answer: Greenland measures 2,670 km (height), which is 2.2× as big as the reference, California at 1,240 km.
The span is real, but Mercator maps still inflate Greenland’s area by about fourteen times.
Common miss: players tend to compress Greenland when it sits beside California — big things get squeezed, small familiar things get stretched.
Answer: the contiguous United States measures 4,500 km (length / span), which is 1.1× as big as the reference, Australia at 4,000 km.
The lower 48 stretch roughly 4,500 kilometres coast to coast.
Common miss: players tend to compress the contiguous United States when it sits beside Australia — big things get squeezed, small familiar things get stretched.
