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.


Ocean tides are caused by the complex interplay of three astronomical bodies: the Sun, the Earth and the Moon. Both the Sun and the Moon exert a gravitational pull on the Earth's water. The resulting force of the Moon's gravity creates two tidal bulges on opposite sides of the Earth.


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.


Spring tides occur during the full moon and the new moon. Neap Tides 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. Neap tides are especially weak tides.


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.


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.


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.


The moon’s gravitational pull, which is much stronger than the sun’s gravitational pull causes ocean levels (tides) to rise and fall twice each day. The moon is a very different place than the Earth.


the phases of the moon don't affect tides. Tides are caused by the moon's gravity, the moon is always at the same distance from Earth. Sun also causes the tides. so if the sun and the moon are ...


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.
