An equal-area map is created by treating the earth like an orange. To get the orange peel to lay flat, it is necessary to make a lot of cuts (Fig. 1.8 A). To make a cylindrical-projection map, think of the earth as a clear globe with black outlines of its features lit from within. To make a flat map, the globe is wrapped in a paper cylinder and the projections of the outlines are traced (Fig. 1.8 B).
Using two maps of the world, determine approximately how much of the surface of the earth is land and how much is covered by water.
