    I must thank civfanatic for telling me about how the African landmass on maps is not properly depicted.

    This is how a normal map of the world looks

    Africa is the second largest continent, then why does it look smaller than North America?

    This is how big Africa really is

    Trackwhack, let me just point out that in most cases Africa is the one that is represented in its true form and size. Other landmasses like N. America, Antarctica, Northern Asia, Greenland etc are heavily distorted. For example, in most world maps, Greenland will be about the size of Africa, while in reality Africa is about 15 times bigger.
    It depends on where the center of the map is and what projection is used. Normal maps that we see in our daily lives usually have minimal distortion for regions near the equator and maximum for polar regions.

    There are several varieties of projections. Check them out:

    This is a trick of the mercator projection, where we try to depict a spherical mass on a flat surface. Places closer to the equator will look much smaller than they really are, and places away from the equator will look much bigger than they really are.

    So, Russia is not as huge as it looks (though it still is pretty huge), Greenland is not as huge as it looks, India is not as small as it looks, and Africa is not as small as it looks.

    Also, try this - open google maps and "travel" Northwards and Southwards of the equator, and see how the scale of the map changes.

    Off topic, but the map of Africa with all the countries and continents placed inside it reminded me of this:




    I think he is using the Mercator projection, check out Africa in southeast Russia. :D

    Why does India look so big next to USA? I think without Alaska then USA is only twice as big as India?

    I guess only by adding Alaska does USA get to 9,000million squire kilometers?

    Also does any one know how many people have Dark Skin(africa and equatorial regions), Brown Skin and Pale Skin(Europe and East Asians).

    Is there any way to know the proportions of this?

    The USA is about 9.6 M Sq. km or about 9.8 M sq. km. (I suspect the second measurement takes into account territorial waters). And Alaska is about 1.7 M sq. km.
    So, 9.8 M - 1.7 M = 8.1 M ~ 8 M

    Area of India = (just over) 3.2 M sq. km
