What would happen to earth if the moon was destroyed?

First of all it would depend on how the moon was destroyed. Let’s just say the moon blew up into little pieces due to asteroids. We’d no longer watch the phases of the moon at night, but see a clouds full of debris which would probably be brighter than the full moon. But if the moon were dragged off and completely removed, there would be none of its mass left to tug gravitationally on the Earth. One of the effects would be that ocean tides would still happen, but the bulge of water would follow the sun, so you could expect high tides around noon everywhere, every day. Since the solid Earth flexes tidally, it makes sense that there might be some internal grumbling when Earth loses the moon. Like …show more content…

The worst thing would be in the long-term, regarding the Earth’s wobbling spin axis. Right now the spin axis of the Earth very slowly wobbles over 26,000 years, like a slowing wobbling top, because of the tug of the sun. The wobble causes north to not always point at Polaris, a.k.a., the North Star. Experts off the one of the websites I used agreed that the moon acts sort of like a shock absorber to this wobble, keeping it from getting out of hand. It’s possible that Earth without a moon would wobble wildly, sort of like Mars does. The Red Planet’s wobble is so extreme that it may be the cause of some cycles of climate change there. If the same thing happened here, Earth might wobble so much that seasons would become extreme and Earth would be a much less stable and habitable planet. Without the moon the tilt of the Earth’s axis could go from its current wobble of 22 to 25 degrees to a wide ride of zero to 85 degrees, zero would eliminate seasons, and 85 is basically the Earth leaning over on its side. If this happened, the current crisis we call global warming would be a very nice by comparison. Luckily, the wobbling would not
