why can't a map portray the earth as accurately as a globe?

A map is two-dimensional whereas the planet happens to be a sphere. Therefore, you have to distort the globe in order to make it somehow fit on a flat piece of paper.

Because a map is actually a projection of a three dimensional almost spherical planet on to a two dimensional flat piece of paper.
In a Mercator projection map, for example, the map is produced by imagining a very bright light at the very centre of the Earth projecting all the surface features of the Earth on to the inner surface of a cylinder of paper wrapped round the planet which it only touches at the Equator. The cylinder is then unrolled, opened up and laid out flat. In this type of projection, all lines of Longitude are straight and parallel just like lines of Latitude. Because of this, the map produced is only really accurate close to the Equator and becomes more and more distorted the further North or South you look.

A map is 2-dimensional, and the Earth is 3-dimensional. You have to make changes to convert a sphere into a flat piece of paper.

Nice use of copy and paste Doshieal, but we didn't really need all of that.

Because....we already have globes to do that for us.
