Por que a Groenlândia parece tão grande?
Os mapas de Mercator esticam regiões próximas dos polos. A Groenlândia parece grande demais diante de países do equador. Compare Groenlândia e Austrália em Equal Earth. Um mapa útil para navegar não é necessariamente adequado para comparar áreas.

O que Equal Earth preserva
Achatar uma esfera muda suas propriedades. Equal Earth preserva áreas relativas, mas não todas as formas, distâncias e direções. Na borda do globo as formas se comprimem. Escolha a vista conforme sua pergunta.

Por que fronteiras e áreas diferem
A simplificação omite pequenas baías e ilhas. Usamos limites Natural Earth na escala 1:110 milhões e calculamos áreas com formas esféricas simplificadas. Dados oficiais podem incluir águas e territórios de outra maneira. ≈ indica uma estimativa.

Africa is bigger than the map in your memory
The equator crosses Africa, but familiar rectangular maps give northern regions extra space. Compare Africa with countries you know to get a sense of its size.

Why a country looks smaller at the globe’s edge
A globe avoids the familiar rectangular world, but its screen image still compresses the edge. Separate spherical area from visible footprint.

Why the shortest flight looks curved on a map
A straight line on the screen need not be the shortest path around Earth. Compare great-circle paths with compass bearings, and see what a route illustration can tell you.

The map edge is not the International Date Line
Longitude wraps around, a flat map has a seam, and calendar dates have a boundary. These three ideas are related but not identical.

Antarctica is a continent, not the bottom border
A stretched southern strip can hide the shape of a whole continent. Compare Antarctica on Mercator, Equal Earth and a polar globe view.
