Tags: mechanical engineering See more , See less 8 Answer Add Tags Answer Interview Answer 1 Answer ▲ 0 ▼ There are two high tides because the moon's gravitational field pulls on the water around the earth and the earth itself (the earth also pulls on the moon) as it orbits. The first hight tide occurs on the side of the earth that is closest to the moon, and the second high tide occurs on the side that is farthest from the moon, where water is "left behind" by the motion of the earth towards the moon.
