The Effects of the Moon Phases on Ocean Tides ... During the waxing gibbous and waning crescent phases, the Moon is approaching its full and new phases, respectively. Because of this, the resulting tidal bulges will increase in size until they reach their maximum during the spring tides.


The greatest difference between high and low tide is around New Moon and Full Moon. During these Moon phases, the solar tide coincides with the lunar tide because the Sun and the Moon are aligned with Earth, and their gravitational forces combine to pull the ocean’s water in the same direction. These tides are known as spring tides or king tides.


We call this a quarter moon because only 1/4 th of the Moon is illuminated (don’t forget the half of the Moon that you can’t see!). Compare the positions of the Sun, Moon, and Earth during spring tides and neap tides. Why might this affect the tides? Results. A full moon is when the Moon is opposite of the Earth, relative to the Sun.


The Ocean's Tides Explained The alternating pattern of rising and falling sea level with respect to land is what we know as the tides. What causes this "motion of the ocean"? In one word, gravity. Specifically, the gravitational forces of the Sun and Moon.


Less pronounced tides, called “neap tides,” occur when the Sun and Moon are perpendicular, forming a right angle with the Earth at its apex. Neap tides occur because the pull of the Sun and Moon are pulling from different directions, creating a balancing effect.


How does the moon affect the tides? Grant Petty. Gravity is what makes the ocean tides happen. Gravity is the attractive force that all matter exerts on other matter, and it’s what holds us to the Earth. All the matter that makes up the Earth attracts each other, and the result is that it pulls itself into this round ball, which we know as ...


The phases of the moon also affect tides. When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual. Called spring tides, these tides occur when the sun, moon and the Earth all line up. The added gravity of the sun can make the oceans bulge more than at other times.


Tides result from a gravitational tug-of-war between Earth, the Moon, and the Sun. The Moon's gravitational force is slightly stronger on the side of Earth that is closer to the Moon than it is on the side of Earth that is farther from the Moon. This small difference in the strength of the Moon's gravitational force pulls Earth's oceans into an elliptical shape.


Tides are affected by the gravitational forces of both the moon and sun, which cause two low tides and two high tides each day. In explaining the phases of the moon and tides to children, teachers should make the young students aware of the effect of gravitational pull on tides.


Neap tides occur halfway between each new and full moon – at the first quarter and last quarter moon phase – when the sun and moon are at right angles as seen from Earth.
