How do the sun causes a tides?

Tides are primarily caused by the gravitational pull of the moon, but the sun also plays a significant role. While the sun is much larger than the moon, it is farther away, so its gravitational effect on Earth's tides is less pronounced. However, during full and new moons, when the sun and moon align, their combined gravitational forces result in higher high tides and lower low tides, known as spring tides. Conversely, during the first and third quarters of the moon, when the sun and moon are at right angles, we experience neap tides, which are lower than average.
