How would the tides on earth be affected by the absence of the moon? there would be no spring tides. the tides would occur at a much lower intensity. the high and low tides would occur more frequently. there would be no tides. the tides would remain unaffected.

I think the best answer is: The tides would occur at a much lower intensity.
The forces that create tides include centrifugal forces from the earths rotation and also the gravitational force of the sun. Although these are much smaller than the force exerted by the moon we would still have tides.

The density would be 1.622
