what would happen if the moon got closer to Earth?
Everything will change but why?

Jeez people, this guy ask what would happen if the moon got closer to Earth, and what kind of answers do you give em? "It's getting further away".
Anyway, if the moon would get closer by time, it will increase it's pull on Earth oceans first. The tides become more extreme. Most coastal area's would be flooded two times each day. What happens after that I cannot imagine. I guess our atmosphere will be extreme and finally if the Moon hits Earth, nothing will survive. Earth crust and the entire moon will be completely destroyed and the Earth will be covered in one big lava ocean. No one on Earth would survive that impact.

The main thing to understand is that it would only be temporary, because normal physical forces are moving the moon away from us, and would do so again. The mechanism for this is tidal friction. The moon raises tides on the earth - but the highest point of the tides is not precisely under the moon - it lags a little. There is therefore a modest 'sideways' force between the tidal bulge and the moon, and that causes an energy transfer.
Of course, the closer the moon is, the higher the tides it causes, and so the greater the tidal friction. So the 'problem' of the moon being closer would be self-correcting qualitatively and quantitatively, if you see what I mean.
Note that the erath and the moon actually raise 'land tides' on each other as well as the oceans rising and falling. However, since the land is pretty rigid (at least compared with the oceans), these are very small. All the same, tidal forces are suspected of being responsible for at least some earthquakes. That would be more likely, of course, if the moon were closer to us.

The high tides would get higher and low tides lower. And the daily and monthly peaks would get closer together. If it happened quickly enough that tidal breaking lagged we'd see the Moon to orbit in apparent retrograde; and the far side of the Moon would come into view for the first time ever to the Earth bound.
You would need to specify how much closer to specify any detail. If we only shorten the lunar month by a day I'd not think there'd be much of a change; shorten it to a week and there'd likely not be a sea side resort left at the end of the year.

It could happen, say, if a massive-enough body collides with Earth and either caused it to get closer to the moon or to stop spinning as quickly on its axis. It could also happen if a massive body collides with the moon in such a way as to cause its orbital path with Earth to diminish sufficiently.
If that happens, the moon would eventually collide with the Earth. It would certainly change many things and could even result in cessation of all life on planet Earth. Certainly, many life forms on Earth would die due to the change in Earth's atmosphere. How does anyone know this? Because there's evidence that something similar happened before.
About 65.5 million years ago, the age of the dinosaur ended abruptly as a result of a change in the atmosphere that blocked sunlight and caused an immediate and traumatic ice age as temperatures dropped rapidly and severely. The culprit? Scientists seem to believe it was either an asteroid that hit the Earth's surface at high velocity and kicked up a lot of dust into the atmosphere, or that a super-volcano erupted and spewed enormous amounts of ash into the atmosphere.
A colliding satellite the size of the moon could do the same, and would change everything!

Earth's tides could be tousled and all human beings might run away and products of the Moon might come to the Earth and can probably injury the Earth and kill off the human inhabitants and a few huge animals like elephants,giraffes,people and so on the only creatures could be small mammals,ocean animals,and small micro organism interior the floor. each and all the products of the Moon might come down and rain on us think of the moon's products coming down from the heavens and it replaced into raining XD which would be humorous and all that. however the no longer humorous area is that us people will according to hazard substitute into extinct. yet truly the Moon is shifting far flung from us approximately below an 0.6 centimeters a 300 and sixty 5 days and via the time of 2100 it would be 2 x 239,000 miles far flung from us the Earth.

The Moon follows an elyptical orbit with the Earth in one of the ellipse's two foci. Therefore, the Moon *DOES* get closer to Earth, then moves out and gets farther from Earth, then comes back again; this happens over the course of one month (more precisely, about 29,5 days). The closest approach is about 356 thousand kilometers, the farthest distance is about 406 thousand kilometers; so it varies in distance from Earth about 50 thousand kilometers over one month, every month, without people noticing any appreciable changes.
So the question you should be asking is HOW MUCH would you want it to get closer to get an idea of the effects?Source(s): http://en.wikipedia.org/wiki/Moon

The Moon gets closer and farther away for Earth EVERY month. Everything changes all the time. Either adapt and keep up or get left behind. Survival of the fittest.

The moon is actually moving away from the earth, very slowly.

It would be repulsed by liberals all over this planet and it would probably move farther away.
