1. Map Projections

2. Every map of the earth has some kind of distortion
Every map of the earth has some kind of distortion. It could be distance, shape, size or direction.

3. Mercator
The big flaw is that size and distance near the poles is greatly distorted. It’s old (1500s)

4. Robinson
Polar areas are flattened, but it generally just has minor distortions.

5. Goode’s Interrupted Equal-Area
Shows true size and shape of landmasses but distances are distorted.

6. Winkel Tripel Projection
Most used projection in reference maps because it does the best of balancing distortions. Even the poles have little distortion.

7. Latitude and Longitude
Latitude lines run laterally across the globe to show distance from the equator. Longitude lines run up and down the globe and converge at the poles to show how far something is east or west from the Prime Meridian (which runs right through London).

9. International Date Line
Let’s hope the good people at YouTube can take care of this one:
