1 Maps and Map Projections

2 Map Projections -A globe is the most accurate portrayal of the Earth and the size of its land masses -For obvious reasons, globes are not as convenient as flat maps (i.e. size, shape) -However, there is difficulty portraying a spherical object on a flat surface -For that reason, three map projections have been developed to portray what we see on a globe -Interrupted, Mercator and Mollweide

3 Mercator -Mercator maps are most commonly used however drastically distort objects farther away from the equator.

4 Mollweide -Mollweide distorts landmasses however not the proportions of those continents and countries.

5 Interrupted -Interrupted does not distort land masses and maintains accurate proportions. Interrupted does not however allow for accurate measurement of distance.
