Detailed explanation-1: -A solar eclipse happens when the Sun, Moon and Earth are perfectly aligned. The Moon blocks light from the Sun and casts a shadow on Earth. The eclipse is visible to anybody within this shadow. A solar eclipse can be either total or partial.
Detailed explanation-2: -When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.
Detailed explanation-3: -Spring tides always happen when the Moon is at the full or new phase, which is when the Sun, Moon and Earth are in alignment. Neap tides occur around the first and last quarter phase of the Moon, when the Moon’s orbit around Earth brings it perpendicular to the Sun.
