Geographers use maps to show important features of Earth, such
as its oceans and continents.

But every flat map of Earth involves some distortion.

As a result, the size or shape of landmasses or large bodies of water may be distorted, and the distance
between places may not be accurately shown.

To deal with distortions, mapmakers use different map projections. Many
projections are named after the mapmakers who designed them.

For example, Arthur Robinson designed the Robinson projection. It is a popular
projection because it balances the distortions of size and shape, resulting in a fairly accurate picture of the world.

Lambert Projections show polar areas that other maps distort. A Lambert projection is a circular
map.

It shows size accurately at its center, but not distance or
shape. It is good for showing the areas around the North and
South pole.

Most other map projections distort the shape and size of the Arctic
and Antarctica.

Mercator Projections show direction but distort size. Gerardus Mercator
designed his map projection in 1569. It shows directions between places
accurately near the equator.

But it distorts the size of continents, especially near the North and South poles. This is
called area distortion.

Eckert IV Projections show size but distort shape. The Eckert IV
projection is an equal-area map.

Equal-area maps show the sizes of places accurately. However,
they distort shape near the poles. This is called shape distortion.

Goode’s Homolosine Projections show continents but distort oceans. These
maps use a trick to help us see how the continents compare in size.

It deletes bits out of the oceans. This allows the continents to stretch
without distorting their shapes. But it distorts the shape and size of the
oceans.
