directions are accurate, uses lines of latitude and longitude

what are some things mercator map projection distorts?

distance in the lines of longtitude, and the land closer to the poles seems bigger

What are some strengths of robinson map projections

no major distortion, oval more like globe than rectangle

what are some things robinson map projection distorts?

area, shape, size and direction are all slightly distroed

What are some strengths of peters map projection

sizes of landmasses are accurate

what are some things peters map projection distorts

the shapes around the poles are innaccutre
