    which is the one statement that correctly provides a piece of evidence that the continents have drifted in the geological past.

    .................................................. .................................................. ..................




    The presence of humans on all the continents indicates that the continents were once all joined together.

    The current lattitude of climate sensitive sedimentary deposits is inconsistent with the latitude where they were originally deposited.

    The Hawaiian hot spot has been stationary for the last 70 Ma.

    Basalts are erupted at mid-ocean ridges.The asthenosphere can flow at a very slow rate.

    Rather than give you the answer, perhaps I can teach you to find it (which is the point of your homework assignment anyway).

    You should really start with the assigned text(s) of your class and consider reading the relative chapter. This should take only an hour or so (and is the best use of your time since there is far more information to be gained).

    If the answer doesn't stand out, check the index for "continental drift" and flip to the page(s) indicated. I've no doubt the answer will be at one or more of these pages.

    If, on the off-chance you don't have access to the text, you might find the following links, which I've applied to your questions, helpful. Move your mouse around a bit since there might be more than one link per sentence.

    If you fully read each of these WikiPedia links, one answer will stand out from the rest.
