    Default Draining the oceans

    Hi folks

    I just ran into this XKCD-What-If:
    http://what-if.xkcd.com/53/

    And thought, it could be quite interesting, speculating about how the earth looked like, if the oceans get drained ..


    A contest revolving around this topic would include the creation of several maps:

    1.) The basic map

    2.) Drain the oceans by X meters

    3.) Drain the oceans by Y meters

    4.) Drain the oceans by Z meters

    Or whatever number of maps you deem appropriate.



    Just a thought



    Kind regards,
    Kai

    I think it could work, as a generalized 'present a map showing sea level drop' topic. Then folks could interpret that many different ways, from Earth with lowered ocean levels to dead seas, etc.
