I mean, technically, "seismology" is all about shaking the earth.

  The next level of pedantry is pointing out that it’s not limited to the earth.

    And the level after that is making the distinction between "earth" and "Earth". And before the quartic pedants say "well, all earth is on Earth", there's some in planes, on the space station and probably a few molecules scattered by impacts and human space exploration. Quintic pedants will then question if, after being in space environments for long enough, a scrap of outgassed irradiated earth is still properly called earth? So isn't all "real" earth still gravitationally bound to the Earth? Sextic pedants may be the first to notice everyone else has left them to squabble and gone to the pub.

      > isn't all "real" earth still gravitationally bound to the Earth Another (sub)level of pedantry: earth will always be bound to the Earth because gravitational force never really reaches zero no matter how far the objects are from each other thus earth can still be called earth?
