The Moon's Gravitational Pull Does Not Necessarily Cause the Tides on Earth

The Moon's gravity, at its strongest point, is roughly 10 million times weaker than the Earth's gravity. What really causes the tides is the gravitational pull in the space between the Earth and the moon. The Earth's surface is 71% water, so any small pull from the gravitational field between the Earth and the moon will ever so slightly change the tides, but that is not what determines them.
