On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
Why are there 2 tides?
This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis. ... Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes.
Why are there two tidal bulges at once?
The deformation of land and water of the earth due to the gravitational forces of the moon and sun acting on every part of the earth. This deformation results in two "tidal bulges" one on the side of the earth nearest the moon, and one on the opposite side.
