Away by an inch a year due to tidal drag. The moon is what keeps our day at 24 hours. Eventually as it moves farther and farther away the Earth's rotation will slow to about a 47 hour day.

you're the two incorrect. The moon isn't pulling the Earth everywhere, and the Earth isn't being pulled into outer area. The moon's gravity motives tides on earth, and those tides reason friction between the sea and the seafloor. And this friction is extremely steadily slowing the Earth's rotation (via some seconds a century). The regulation of conservation of momentum states that the full momentum of a gadget (the rotation of the Earth and the moon and the orbits of the two products around the centre of gravity) has to stay an identical. So if the Earth is slowing down, then something has to alter to safeguard momentum. that would desire to be the moon rushing up (which it won't be in a position to do) or the moon moving extra desirable from the Earth (which it may do, and is doing). The Earth/Moon gadget is held in orbit via the solar's gravity, and the only way the Earth would desire to be pulled into outer area exchange into via yet another great merchandise's gravity (and there is not any great merchandise everywhere close to via to pull the Earth everywhere). The moon truthfully does not have the mass or gravity to pull the Earth everywhere (its the Earth that keeps the moon in orbit).

The moon is slowly moving away from the earth and is making the earth tilt a little more off its axis.Eventually the moon will be too far away to affect the worlds tides. The gravity that the earth and moon share will be non existant and bad things will happen to the worlds vegetation and climates! The axis of the earth will be really weird and the climates will change almost daily depending on where you are on the planet. You may not want to be here when this happens existance will be extreme in the least!

Although the moon moves closer, then farther, then closer, etc to the Earth as it orbits, the average distance (the semi-major axis) is getting farther by about an inch per year. This was confirmed by laser instruments set up on the moon from the Apollo missions. (to answer a question that will undoubtably follow, yes, people landed on the moon (might as well answer the next, the sky is blue because of reyleigh scattering)).
The moon getting closer and farther and closer and such is a result of the moon's orbit not being a perfect circle.

Yes, the moon is slowly moving away from the earth, a couple inches every year

Do not be concerned by the above answer, the moon is moving away, but it has always been moving away from the Earth.
It has been quite happy for 4 billion years, and even though the day will get less [slightly] it is nothing to worry about in terms of human existance!

it is moving away at a miniscule rate but technically for it to orbit the Earth it is actually falling toward the earth, but its angular momentum causes it to go around.
