How Does Gravity Affect the Tides of the Ocean?

The moon pulls the ocean, making it rise and fall like a big wave. When the moon is close to Earth, its gravity makes water on the side facing it go up, that's a high tide. On the opposite side of Earth, another high tide happens because the moon also pulls the Earth away from the water there. The sun helps too, especially during full and new moons when tides are biggest.

The moon’s gravity is like a giant magnet, it pulls the ocean toward it. When the moon is near, it makes the water go up, creating a high tide. On the other side of Earth, there's also a high tide because the moon pulls Earth away from the water there. The sun adds to this pull sometimes, making tides even bigger.
