Why do the phases of the Moon, affect the tides?

Asked by MrGrimm888 (13672points) May 16th, 2018

If it’s gravity, why does light matter? The Moon is the same distance from the Earth, regardless of it’s phase. So. Why does it make a “higher” tide, when full, opposed to other phases?

You know, a full Moon makes a higher than normal “high tide.” Why?...

Phase does not matter, orbital proximity does.

When the moon is full it is directly opposite the sun and the gravitational effects of the sun and the moon work together to produce a stronger effect. A new moon lies between the sun and the earth and again the gravitational forces are aligned for maximum effect. During other phases of the moon there is an angle between the sun and the moon and the gravitational forces tend to cancel out.

The gravitational pull. The moon tugs on the ocean’s surface. So, since the moon changes position around the earth throughout the day that affects the tides in the different places around the earth, and you get high tides and low tides daily.

Edit: the sun does affect ride too. When the sun, moon, and earth are in line the tides can be especially high. Being in line or out of line is what creates the phases of the moon, as the earth spins, circles the sun, and the moon circles the earth.

You should google, there is probably lots of information online.

The moon’s gravitational pull.

Also, Professor Brian Cox explains how the centrifugal force as well as the gravitational force of the Earth experiences.

The moon rotates around the earth, but there are positions that have differing effects. Perigean is especially influential to the tides as explained on this website link from the National Ocean and Atmospheric Administration.
