Hard to believe people don't know about Nova Scotia, and it's amazing beauty. My Grand father was a potatoe farmer, and herring fisherman in Margarie Forks In 1918 untill he decide he'd picked his last potatoe. The snorkeling in Nova Scotia is fabulous. It's not for the faint of heart. The water is not that cold because of the Gulfstream eddies; but the tides can be a bit scarry for the uniniciated. Try a tidal float down the bay of fundy. its dangerous but wicked cool. Learn your game first.

@nanone1994 haha I'm not that smart, just in college. Were supposed to pretend to be smart. Anyway glad I can help! If you have anymore questions let me know.

[nanone1994]

@nyrplayer thank you very much for your explanation I admire you for your intelligence it's rare to find somebody understands physics! you helped me a lot my final examination is next week and this was a great push up and raise the morale for me because i feel that I understand everything ..

many thanks for you ... :)

@nanone1994 that is what makes the water rise at certain times of the day. When the moon is right above you is when the tide is the highest. It can get even higher when its a new moon (which means its in line with sun). Just note that because the moon is close to earth it has a stronger pull on the tides than say the sun.

If it helps you understand a little better, just note that everything on earth is being pulled by the moon, even you yourself is being pulled by the moon.

Its a lot to know

@nanone1994 Think of a see saw, with a 100 pound person on the left and a 40 pond kid on the right. In order to make it balance we move the fulcrum of the see saw closer to the heavier side. In the case of the sun and earth though, the sun is so much bigger than the earth in terms of mass, that this fulcrum point is so close to the sun that we pretty much make it the center of the sun.

Now in terms of the tides this level of attraction from the moon and sun pull on the water on earth.

@nanone1994 To go a little farther you were probably taught that the moon revolves around the earth (with the earth being the fixed point of the orbit). While the earth orbits around the sun (with the sun being th fixed point of the orbit). In reality the masses (lets say the earth and moon for example) are actually revolving around one with a fixed point in between them except this point is closer to the earth because it is the bigger mass.

@nanone1994 Well Newton discovered that all objects in the universe attract each other. For example, say you have one grain of sand on a table. you lightly put your thumb on it and it sticks to your thumb. The grain of sand and the thumb are attracting each other. You can apply this same theory at the planetary level. Meaning that the earth and moon attract each other, with the earth being the bigger the mass. Same thing with the earth and sun.

@i7887 hello ... your comment got my attention! well...i am a 15 years old student and yesterday the teacher gave us a lesson about the tides and he told us its caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.

and you're saying the earth is getting pulled towards the moon!!!!!!can u explain more please..? i am really interested in this thing ...

I think this is just a really old video.

Silly Oceanographers, so many have no idea what causes the high tide on the opposite side of the Earth The rotation of the Earth is not the real reason. The simplified answer is that since the Earth is solid and water is not, the gravity acts on the center of the earth which is further away from the ocean. Meaning the Earth is getting pulled towards the moon harder than the ocean in effect "leaving the ocean behind". Again this is a greatly simplified way of looking at it.
