Does the sun play a role of effecting the tides?

Question

Sun effecting the tides

Answer 1

The strength of the sun's gravity is 179 times that of the moon's but the moon is responsible for 56% of the earth's tidal energy while the sun claims responsibility for a mere 44% (due to the moon's proximity but the sun's much larger size).

From: http://oceanlink.island.net/oinfo/tides/tides.html:

The Sun Tide
The tides are caused mainly by the gravitational attraction of the moon and the earth, but there is also a gravitational attraction between the earth and the sun. The effect of the sun upon the tides is not as significant as the moon’s effects. Basically, the sun’s pull can heighten the moon’s effects or counteract them, depending on where the moon is in relation to the sun.

In one month, the moon rotates around the earth. When the moon is between the sun and the earth (at new moon), the sun’s gravitational pull is in the same direction as the moon’s. During these days the high tides are higher and the low tides are lower than they'd be with just the moon’s pull alone. This is called spring tide.

The same thing happens when the moon is on the direct opposite side of the sun (full moon). The two gravitational forces work together to make high high tides and low low tides.
When the moon is in its first quarter or its last quarter, the sun’s gravitational pull is in perpendicular direction to that of the moon. The sun pulls water away from the areas of high tide to the areas of low tides, resulting in lower high tides and higher low tides. These are called neap tides

Answer 2

Yes. Its effect is about 40% that of the Moon.

Tidal effect is proportional to the mass of the body causing the tides (e.g., Moon vs Sun) and inversely proportional to the CUBE of the distance.

When the Moon and the Sun are in line (e.g., New Moon, Full Moon) the effects are added and we speak of 'Spring Tides' (they 'spring' onto action). When they are perpendicular (First Quarter, Third Quarter Moon), we have much smaller tides (calle 'Neap' tides); The Moon's tide wins over the Sun's.

The Sun also has an indirect effect in that the Sun's tidal effect will slightly alter the Moon's orbit: it acts as if the orbit itself were an object. When the Sun is in line with the major axis of the Moon's elliptical orbit, the orbit becomes even more elliptical (the Moon's apogee is even further away from Earth than average). When the Sun is in line with the minor axis of the Moon's orbit, the orbit is 'squished' into a more circular shape (apogee is less far than average). As the distance between the Moon and Earth has an effect on the height of tides, then this effect of the Sun on the Moon's orbit does have an influence on the tides on Earth.

Answer 3

The sun, along with many other factors all affect the tides. The larger part of these effects comes from the sun's graviational pull, but not only because the sun is putting the water towards it. The forces the sun creates as the earth rotates and orbits around the it also move those enormous massess of water. This, along with it's heat and some help from the moon also creates ocean and wind currents that determine not only the tides but the climate of the earth on various times in various locations.

Answer 4

Yes! the sun's gravitational pull shifts the water further out than Earth's rock, which causes great tides. The intensity of the tide is caused by the angle the moon and the sun are at.

Answer 5

It s more like a hack&slash with Diablo 2 elements. Those guys literally wipe out entire cities. Other books could also become hot videogames or movies: The epic of Gilgamesh, Beowulf(they made video games and movies after this), the Illiad, and the Odyssey. Maybe more, but I cant remember....

Answer 6

the sun doesn't move ( well technically it does) so it wouldn't really change anything
