This is probably a dumb question but I was wondering if the earth had a frequency. I would think with such a massive object there would be a certain background vibration from tectonic plates moving around.

Yes - and the vibrations from earthquakes and such tell us about the structure of the earth

cool. Does it vibrate at a certain frequency or is it just random?

That's a great link, Mr. Special. I don't currently have time to peruse it, but will in the near future.

The first part to your question "I was wondering if the earth had a frequency" can also be answered from an electromagnetic standpoint. Schumann resonances are frequencies in the EM field of the earth. Essentially, the ground the ionosphere create a waveguide and is excited by current induced from lighting. The peaks are at 7.83, 14.3, 20.8, 27.3 and 33.8 Hz.
