Unformatted text preview: The bulges actually occur on both sides of the Earth. The side that's closest to the Moon feels the strongest pull and bulges out, and the side furthest from the Moon feels a lesser pull and is sort of left behind (since the center of the Earth also feels the pull, more than the water on the furthest side of the Earth). This is shown in Figure 12. Figure 12. The Moon's pull on the water and the Earth produces bulges on the two sides of the Earth. The degree of the pull is shown by the arrows, with the side nearer the Moon having the largest pull, and the side further having the smallest pull. Since it takes only 23 hours and 56 minutes for the Earth to rotate, coastal locations will pass through the high water bulges (have high tides) two times each day. Remember, the motion of the Moon is much slower, so the Earth actually rotates through the tides....
