If the moon were knocked out of orbit. What affect would that have on the Earth?

"The Earth would lose sea tides and other water tides. This would mean the sea receding in some parts of the world and flooding in other parts. I also think that the Earth will ""wobble"" on its axis and its path of revolution around the sun would change. That would mean change in the duration of the day and the year, I guess that would mean toal destruction."
