What would happen to the tides if there was no moon?

Answer 1

The moon is actually moving away from the earth, very slowly. This is caused by some interesting tidal effects. Someday hundreds of thousands or millions of years from now there will be no such thing as a total solar eclipse because the moon will be too distant to completely block the face of the sun. If the moon were ever to get closer, we had better hope that it also gets a little faster. If it didn't it would come crashing down eventually and catastrophically. The closer orbiting bodies are to their hosts the faster they move through their orbits. At one time it was theorized that the moon formed by being literally thrown off by the earth in the days when the earth was nothing but molten rock. Somehow, people thought, the surface bulged at one point and a clump of material broke free. One problem with this theory is that extrapolating backwards from the moon's current distance and velocity, at the time of its break from earth it would have had to be moving in its orbit at a velocity that is impossibly fast. This can't have been the moon's origin.

Answer 2

if the moon did not exist, the earth would not light up in the night. the moon gives us light in the night.

Edit : Also the tides would be much lower, caused only by the Sun.

Scientists say the Moon helps to stabilise the Earth's axial tilt, as well.

Answer 3

Tides are almost entirely caused by the moon, so without the moon there would not be any significant tides.
