High tides are predominately produced by the

1) strong gravitational pull of the Sun,
2) centrifugal force created by Earth-Moon orbit,
3) differences in gravitational pulls of the Moon on opposite sides of Earth,

which is due to
4) rotation of Earth and Moon about the Sun.
5) Moon pulling with significantly more force on the closer side of Earth than on the farther side.
6) the Sun's pull on Earth being 200 times stronger than Moon's gravitational pull.

Question 2

If the Moon were covered with water, it would have

1) one high tidal bulge,
2) two high tidal bulges,
3) three high tidal bulges,
4) no tidal bulges,

which would follow from
5) the same reason that Earth has two high tidal bulges.
6) no centrifugal force tide would exist on the Moon.
7) the Moon being much less massive than Earth.
8) the center of mass of Earth-Moon system that lies halfway to the Moon.
