Why Dont the Planets Orbit the Solar Equator?

Or at least no major one...

None strong enough to cause tides, for sure.

[ZEE]

then what causes the tides?

[ZEE]

then what does?

[Kuciwalker]

Moon's gravity

this is a very complicated topic gentlemen, and one that is HOTLY debated in MANY scientific circles... if you look up "moons magnetic pull" you are bound to find stuff on google as you will if you type "moons gravitational pull." but one is a direct result of the other. no more no less

Technically by the gradient of the moon's gravitational field across the Earth's surface.

Since the oceans are more fluid than rock they respond more quickly to this changing gravitational gradient than does land.

Local geography determines the precise magnitude and timing of tides.

Oh, and for Kuci's edification, tidal stress due to the gradient of the Sun's gravitational field accounts for a significant part of the overall effect. IIRC the Moon's tides are ~twice as strong as the Sun's tides. When the two line up you get the strongest high and low tides. This happens once a month or so.

You're an idiot.

I have to leave. Kuci, you deal with him.

[ZEE]

gee thanks, but i dont get riled that easily... and im more than capable of defending myself...

Gladly.

Here's a good diagram of the tides (the moon is off to the right):



If the Earth had no moon, the surface of the ocean would be determined solely by the Earth's gravity (it's an equipotential surface) and would therefore be basically spherical. However, the ocean and the Earth are both orbiting the moon*. On the side of the ocean closest to the Moon, the gravitational field is slightly stronger than at the center of the Earth (or the sides of the ocean facing perpedicular to the moon). Thus, the water on that side is pulled closer to the Moon than the rest of the Earth or the ocean. By the same math, the water on the far side of the Earth is less attracted to the Moon than the rest of the ocean, so it ends up going even farther away from the Moon. Result: the thing in the picture.

I don't know WTF you're getting magnetic fields from.

* well technically they are orbiting the common center of mass. Not important.

[ZEE]

not magnetic FIELDS Kuciwalker... magnetic PULL, WE pull the moon... Gravity ISNT pull, its momentum.

... WTF, kid, WTF.

Gravity is a force, kid. F = G*m1*m2/r^2 and all that jazz. Magnetism is a force, too, though the formula is a little different.

Not the left?

you learned that from Newton eh?
im quoting EINSTEIN...

an apple fell on Newton, and he thought he was einstein

PS- i know newton came before einstein did, its a joke
