If a large planetoid hurled through the solar system and came near enough to Earth?

Question:

What kind of disruption would occur. What about Gravity? What about the EMF? Could it cause polar changes? could it cause a massive geologial disruption like world-wide volcanic and earthquake activities? Could it ostensibly change geographic features like land masses, ocean depth mountain ranges/

Could it be sufficiently catastrphic to cause an event as major as Noah's flood?

Answer:
Yes

It could pull the moon out of orbit AND If we lost the moon, man that would be bad. The earth would lose its stability and the poles would shift.

the entire climate would be messed oceans would no longer have tides...things would be very ugly.

Oh but life could still exist.

And without the moon how would people change into werewolves?!??

That would directly depend on the mass of the object, and the proximity to earth. If its big enough and close enough, it could be a total extinction event, but the probability of that happening is astronomically small. You're far more likely to get struck by lightning right after you win powerball.
