Understanding Tides

The video explains how tides work, focusing on the gravitational interactions between the Earth, Moon, and Sun. The Moon is the primary influence, creating tidal bulges that result in high and low tides. The Sun also affects tides, enhancing them during spring tides and diminishing them during neap tides. Tidal patterns vary globally, with most places experiencing two high tides daily. The video clarifies that tidal waves are unrelated to gravitational tides and are usually caused by earthquakes.
