Detailed explanation-1: -Tides are highest when the Sun, Moon, and Earth are in a straight line. This happens on Full Moon and New Moon days. Such tides are called spring tides.
Detailed explanation-2: -Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That’s when lunar and solar tides line up and reinforce each other, making a bigger total tide. Neap tides occur when the moon is in the first or third quarter-when the sun, earth and moon form a right angle.
Detailed explanation-3: -During the moon’s quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide.
Detailed explanation-4: -Very high tide is caused when the sun, the moon and the earth are almost in the same line. Such high tides are called spring tides. During new moon and full moon the gravitational forces of sun and the moon work together with combined force and thus this spring tide occurs.
