Subject: RE: Tides: Why do seas 'bulge' on the side of earth away from the moon?

I understand lunar and solar gravity tugs at the oceans' waters and
makes them "bulge" into high tides on the faces of the earth both
toward and opposite the moon.  I can't find a clear explanation for
the bulge on the "back side" of the earth.  Does gravity depress the
ocean floor?  Is centrifugal force involved?  Is acceleration of
the earth toward the moon and inertia of the water responsible?
I can't find a clear explanation for my 8th grade science classes.
Thank you for your help.  Lou Taylor
