Ever notice that on many maps, Africa tends to be much smaller than Asia, Europe, and definitely the United States. Maybe this has changed some from when I was a kid and had more of a requirement to look at maps.
All That Is Interesting also provides a table adding up the areas of the countries shown - China, the USA, India, Mexico, Peru, France, Spain, Papua New Guinea, Sweden, Japan, Germany, Norway, Italy, New Zealand, the UK, Nepal, Bangladesh, and Greece - and Africa is still a bit bigger!
