Okay, I'm not sure I believe the diagrams either, particularly the atmosphere one. To the top of the thermosphere, you've got about 100km. Multiply that by the earth's surface area of 510,065,600 km2, and you get a volume of 51,006,560,000 km3. Radius of a sphere with this volume is 2298 km, diameter 4596km. (If anyone better at math want to check my volume to radius calculation, I wouldn't mind at all.)
On the map, the atmosphere bubble fits between London and Istanbul, which is only 2505 km apart. If you drew a sphere with about twice the diameter (stretching from London to around maybe Baghdad), you'd have a more accurate depiction.
