The sun exerts almost 200 times more force on the oceans of the Earth than the moon does Why then is the moon more effective in raising tides?
Actually, the Sun's force due to gravity on the Earth (and thus upon the oceans) is approximately 179.5 times that of the moon. It should also be noted that the Sun's tidal forces are still present, but are only about 45.5% as strong as the moon's tidal forces.
.
The moon has a greater influence on the tides because tidal effects arrise from the difference of gravitational forces at different places on the planet, and the force due to gravity is inversely proportional to the square of the distance between two objects. The diameter of the Earth is approximately 12,700 Km. The Earth is approximately 149,000,000 Km from the Sun, so the difference of the force due to gravity from the sun at the near side of the Earth compared to the far side of the Earth is 0.0170%. The Moon, on the other hand, is approximately 384,000 Km from the Earth, so the difference of the force due to the gravity of the moon at the near side of the Earth compared to the far side of the Earth is 6.72%.
.
The moon's gravitational force difference is therefore about 395 times greater than the sun's gravitational force difference. Remember, the sun's overall gravitational force is still 179.5 times stronger than the moon's gravitational force. So to get the moon's tidal forces in proportion to the sun's tidal forces, we take 395/179.5, which is 2.2. Thus, the moon's tidal forces are 2.2 times greater than the sun's tidal forces, or as we stated at the outset, the sun's tidal forces are 45.5% that of the moon's tidal forces.
What else can I help you with?
What exerts the greatest tidal force on the oceans?
It is the moon. The sun is a weak second.
Why does the moon have a greater affect on tides then the sun does?
Though the Moon is much smaller than the Sun, it is closer to Earth than the Sun. So exerts a greater gravitation effect on Earth's oceans and seas.
What type of tides do most of the worlds oceans experince?
Most of the world's oceans experience semidiurnal tides, which means there are two high tides and two low tides of almost equal height each day.
Do other oceans have oceans?
No, there are 7 oceans and seas.
What was Jacgues Cousteau's Field of Contribution?
Jacques Cousteau was a pioneer in marine conservation and oceanography. He is best known for his invention of the Aqua-Lung, which allowed divers to stay underwater for longer periods, and for his work in raising awareness about the importance of preserving the world's oceans.

What exerts a strong pull on water in the ocean?
The Moon's gravitational pull on our planet causes the ebb and flow, (rise and fall), of our earth's oceans.

Where do the oceans border North America?
Oceans almost completely surround North America. They touch North America on the shoreline.
Does the moon give us gravity?
The moon exerts a gravitational influence on Earth. It causes the tides in the oceans, and, when directly overhead, it reduces your weight by a tiny amount.
How many bodies of water oceans rivers seas?
Rivers - an almost infinite number. Oceans, seas etc - depends on where you draw the boundaries.

they live almost everywhere. mostly in the ocean.
How can oceans on the coast can change a landscape?
yes,cuz it get water everywhere. almost
How does the moon create a buldge?
The moon creates a bulge by exerting graviatational forces on the Earth, the same as the Earth exerts upon the moon. This generally affects the oceans and can cause a "bulge."
