      One of the main effects that the moon has on the earth is it’s effects on the tides. If it disappeared, the tides would be much smaller (although we still would have them a little bit, because of the Sun). It also pulls the Earth about and stretches it about, which helps to make the core of the Earth very hot, so perhaps the core would cool down a bit. That could have some pretty dramatic consequences… though geology isn’t my thing, so I don’t know in detail what would happen!

      If it were to disappear overnight, the effects would be catastrophic – the moon affects lots of things like the tides, the weather – and it is bound to the earth by gravity – the disappearance of a large massive object from our orbit could do allsorts from affecting rotation, it could disturb magma under the surface causing huge Earthquakes and volcanic eruptions – it would be devestating to the whole planet. Luckily, it is incredibly unlikely the moon would just disappear!

      Wow you keep asking great questions lwebb!
      So the Moon affect our tides, migratory patterns of birds, the shape of the Earth and the way it streches and squashes, the weather, not to mention it keeps our orbit stable.
      So if it suddenly disappear I think that the Earth would go pretty crazy as our orbit would go kerfluey, there may be more earthquakes and volcanoes erupting, the fish wouldn’t know how or where to swim to get where they need to go, there might be floods or tsunamis, end of the world type stuff me thinks!

      Tides would stop and the weather would calm down a bit. And there’d be no more werewolves.
