Take-Away Points 1. Tides in the ocean are caused by both the Sun and Moon 2. Tides occur because the Sun and Moon pull stronger on one side of the earth than the other 3. There are two tidal bulges on opposite sides of the Earth 4. Solar and Lunar tidal effects can reinforce or weaken each other 5. Actual tide motions in the oceans are very complex 6. Tides are gradually slowing the earth’s rotation
