    Paragraph? For some reason I don't even see a link to the site.

    Great compilation of statistics, a bit worrisome that it's "Procuded" by a "Childcare and early learning" company. :eek: :tongue:

    WMO has dissallowed the 'hottest temperature' record of ElAzyzia. Now the record is officially the 134F of Death Valley, CA, 1913.

    I thought that the dryiest place on Earth was the Atacama desert and not the Antarctica.
    "Up to 1 millon species live in the world's oceans and 2/3 have yet to be described" then 3 bubbles are showed with one with an interrogation mark instead of 2. :)

    I think one of the coolest things in that list was the "Door to Hell" in the ground section

    had never heard of it and after doing some googling ... thought, WOW interesting place to visit :smile:

    There is a town in Pennsylvania that was evacuated due to a coal mine being set on fire and has been burning for over 50 years, I'm surprised that they missed that.

    I had read about the underground fire in Centralia Pennsylvania, it is one of the most dangerous toxic ghost towns in the world. http://io9.com/10-of-the-worlds-most-dangeous-toxic-ghost-towns-1552144947

    Btw, the earth magnetosphere I think should be included in the fact sheet about earth. And that auroras is dazzling, but it's a manifestation that the magnetosphere is failing some of the times to do what it is supposed to do.

    Interesting information.

    Underground coal fires are a worldwide fact of life. I believe there are over 50 known big ones, the biggest in China. Colorado had (has?) one a couple of years ago when a forest file (was it the fatal Thermoking fire?) lit it.

    But....

    On the average worldwide, an acre-foot of soil contains 2 kg of uranium.

    I didn't believe it either, but based on the numbers in the Wikipedia page for Uranium, it seems to be the right order of magnitude.

    You might think about the health hazards from radon gas, and where that comes from.

    As for the Geiger counter, how much shielding would you get from a meter thickness of earth?

    The setting in the Silent Hill movie was largely inspired by that town. I wouldn't recommend seeing it, though.

    Well, he did say "on average," so it's possible there are some very high density locations throughout the world most of us won't ever encounter.
