Question

How is the neap tide different from the spring tide?

Answer 1

• Spring tide occurs when the Sun, Moon, and Earth are aligned in a straight line during the New Moon and Full Moon. The gravitational forces combine, causing a higher than normal high tide, about 20% higher than the normal high tide.
• Neap tide occurs when the Sun, Earth, and Moon form a right angle (quadrature) around the seventh or eighth day of the lunar cycle. The gravitational forces of the Sun and Moon work in opposite directions, resulting in tides that are about 20% lower than the normal tides.
