identify and describe each of the four major flat-map projections.
mercator projection-developed by gerardus mercator in the 1500's streches the poles out as wide as the wpuator to form a map that accurately shows directions and shapes but distorts distane and size, millweide projection- and equal-area map; shows the cor
how can the shortest distance between two points be a curve.
a flat map shows the distance flat but a globe shows the actuall form of the earth and the distance is actually curbed
