Pretty major upheaval, First there wold be no tides other than solar ones. This wold have a major impact on the weather. Probably more earthquakes at first, then probably fewer. (yes, I'm guessing}

That's an excellent question. Obviously, the Earth's tides would subside for one. (Ninja'd by Windrider53 )

It has been surmised that having a relatively large moon was a prime factor in providing its stabilization for life to evolve on Earth, as well as tidal pools forming to aid in the process.

And, in current events, it provides a goal to provide incentive for our space adventures and exploration. Life just wouldn't be the same without it.

Just think of how many more songs would have been written if we had two moons, first comes to mind, Good Moon Rising.

The mechanism of tidal locking to the best of my understanding:
Tidal forces from Earth's gravity cause the Moon's surface to bulge very slightly. If the Moon's rotational period were not exactly the same as its orbital period, the rotation would cause the bulge to be rotated slightly away from the line between the Earth's and Moon's centers. This asymmetry would then cause the tidal forces to induce a torque, which would work to slow down the rotation. After a long enough period of time, the rotation would become slow enough as to become exactly equal to its orbital period, at which point there would be no more torque to slow it down further. That is the case today. Early on in the Moon's history, it was not tidally locked to the Earth.

As Zaurak3 said, the Moon is not the only thing in the solar system that is tidally locked. In fact, most of the moons in the solar system that are relatively close to their host planet are tidally locked. Pluto and its moon Charon are mutually tidally locked. And tidal forces from the Moon are gradually slowing down the Earth's rotation so that, given enough time, it too would become mutually tidally locked with the Moon.
Very interesting, thanks.

Don't look at me like that....

We picked up a new moon a couple of years ago. A rock about 1.5 miles diameter (?) Has been in orbit. Although others have come and eventually left, this one may not leave for a while.
