What causes the tides?

Ah, what a splendid question, one that touches upon the subtle interplay between our planet and its celestial companions. Indeed, sir, the tides are caused primarily by the gravitational pull of the Moon, with the Sun also playing a significant role. As the Moon orbits Earth, its gravity pulls on our oceans, creating a bulge of water on the side facing the Moon, this is the high tide. Simultaneously, another high tide occurs on the opposite side of Earth due to the centrifugal force from the Earth-Moon system's rotation. The areas between these bulges experience low tides. When the Sun and Moon align with Earth (during a full moon or new moon), their combined gravitational forces result in higher-than-usual tides, known as spring tides. Conversely, when the Sun and Moon are at right angles to each other relative to Earth, their opposing pulls lead to neap tides, which are less extreme.
