Low tides would be higher than they are now, because the Moon’s gravitational influence on the Earth’s oceans would be greater.

Volcanic activity on the Earth would decrease, because the Moon’s gravitational influence on the Earth would be similar to the Sun’s gravitational influence, and tidal forces on the Earth would decrease.

Volcanic activity on the Earth would increase, because the Moon’s gravitational influence on the Earth would increase, causing tidal forces to also increase.

High tides would be lower than they are now, because the Moon’s gravitational influence would be similar to the Sun’s gravitational influence on the Earth and would cancel each other out.

High tides would be higher than they are now, because the Moon’s gravitational influence on the Earth’s oceans would be greater.

Low tides would be lower than they are now, because the Moon’s gravitational influence on the Earth’s oceans would be greater, meaning high tides are higher, moving water away from the low tide regions.
