Comeuppance I don't understand how anyone could ever type a question like that when most search engines have a google searchbar built in.
It's like writing a letter asking for someone's phone number, using the phone book page that contains their number.
That's not even a good analogy. There's no good analogy for it because it's so goddamned stupid.
godot It should be "banded iron foundation". For the curious, they're thick sedimentary deposits of rust formed over more than a billion years as dissolved free iron was oxidized by trace oceanic oxygen from early photosynthesis. Only after this sink was exhausted could levels rise enough to support our kind of animal life.
