What would the tides on Earth be like if Earth had two moons identical in size and orbit except that they were 180 degrees apart? What if they were 90 degrees apart?
What will be an ideal response?
If the two moons were 180 degrees apart, then the moons' gravitational pulls on solid Earth would cancel each other and Earth would not be pulled more toward either moon. The forces exerted by the moons on the ocean surface would also partly counteract one another, although the ocean surface would still rise slightly toward each moon because the water on the side facing a moon is more strongly affected by that moon than it is by the moon on the opposite side of Earth.
If the moons were positioned 90 degrees apart the lunar forces would cancel each other out and Earth's oceans would only experience tides due to the sun.
