What causes tides in the ocean?

Tides in the ocean are primarily caused by the gravitational pull of the moon and, to a lesser extent, the gravitational pull of the sun. The interaction of these gravitational forces with the Earth's oceans results in the cyclical rise and fall of sea levels known as tides. The moon's gravitational pull is the primary driver of tides due to its proximity to the Earth. The moon's gravitational force affects the water on the side of the Earth facing the moon by pulling it toward the moon, creating a "bulge" of water. At the same time, the moon's gravitational force also pulls the Earth itself toward the moon, but with a slightly weaker force due to the Earth's greater mass. This creates a second, smaller bulge of water on the opposite side of the Earth, away from the moon. <a href="https://medium.com/@ashwinpalo/what-causes-tides-in-the-ocean-ea46ce3adb4e">Website</a>
