Why does the Moon's gravity have a greater effect on earths oceans tides then the suns gravity?

-- The forces of gravity between two masses are inversely proportional to
the square of the distance between the masses, and directly proportional
to the product of the masses.
-- The sun is about 390 times as far from us as the moon is.
-- The square of 390 is 152,690.
-- So each little pellet of mass in the moon attracts each little pellet of water on
Earth 152,690 times as strongly as the same size pellet of solar mass does.
-- The sun has 27.08 million times as much mass as the moon has. So all the
pellets in the sun put together attract each little pellet of water on the Earth
27.08 million times as strongly as the whole moon would if it were at the same
distance from us as the sun is.
-- Put these two together, and you have 27.08 million times stronger, divided by
152,690 times weaker, = 177.4 times as much force in favor of the sun.
Surprise! The sun actually has a greater effect on the tides than the moon does.

If Earths plates and continents are constantly moving what effect does this have on Earths oceans?
it creates waves sometomes tsunami's
What is is the Smallest of earths oceans?
Arctic
What drives convection in Earth's atmosphere and oceans?
Uneven heating of the Earths atmosphere and oceans by the sun
How does the moon affect the waters of the earth?
Everything has it's own gravity. The bigger the mass the stronger the gravity. The Earth's gravity pulls the moon towards us, but the moon has its own gravity and, as it isn't strong enough to effect the planet as a whole, so instead it pulls the oceans towards it. As the earth rotates one side is always closest to the moon and is effected the most. This pulling of the oceans towards the moon is how tides work
What drives convection within earths atmosphere?
Uneven heating of the Earths atmosphere and oceans by the sun
Which out of the moon or the sun is more attracted to the earths ocean?
The moon has a greater effect than the sun on the earths oceans.
Which pulls with greater force on the earth's oceans the sun or the moon?
The gravity from the Sun is more than the gravity from the Moon. However, the Moon has a greater effect on the tides.The gravity from the Sun is more than the gravity from the Moon.

How does the moon and the sun effect the earths oceans?
The gravitational forces of the Sun and Moon, effect the earths oceans by forming tides.
How does gravity affect oceans?
Gravity can pull water in and out, causing tide like motions. The gravity of the moon and sun, for example pull on the earths oceans and cause high and low tides.
What causes the moon to pull on the earths oceans making an oval shape?
The gravity of the moon
Why does the moon gravity have a greater effect on earths oceans tides than the sun gravity?
Mainly because the sun is about 390 times farther away from Earth than the moon is. That means that there's about 153,000 times as much force between us and a piece of mass in the moon as there is between us and the same piece of mass in the sun.
What is the true relationship between oceans and earths climate?
The oceans have a major effect on climate around the globe.
If Earths plates and continents are constantly moving what effect does this have on Earths oceans?

The rises and falls in the level of earths oceans caused mainly gravity or pull of the moon is?
Tides
Why do tides appear at both sides of the earth?
It is the effect of the moon's gravity on earth's oceans.
When the Moon's orbit is at its closest to earth it has a greater effect on oceans tides?
Yes
Why doesn't water drop off on the underside of the world?
Water and everything else have mass. The Earth is a very large object with a huge amount of mass. Gravity is the attraction between any masses. The Earth wins. The center seeking effect of the Earths gravity beats the oceans and seas and you and everything else here. There is no "underside" to the World relative to the Earths center.
