What force causes oceans to have tides?

you folks do an excellent job with getting the information out and explaining it in lay terms.

There is a lot more to this! Not only does the tide not come in or out ,but the sun also effects the tides. The gravitational waves from both the moon and sun creates bulges of water and we rotate into and out of them creating what we call high and low tides. Watch Neil deGrasse Tyson's video on youtube as he explains it quite well!

Some people on here can be so pedantic

I love the sea

Shelby Carpenter, gravity exists because all objects attract each other, & essentially objects with greater mass pull smaller objects to them. We're tiny compared to the earth, so we stick to it. The moon is much larger, so it pulls back with its own mass & stays in orbit.... etc. (Obviously there's more to it than that, but that's the basic gist of it.)

I've always thought that if our moon can manipulate huge oceans of water what could it do to us humans?

Phil 'sum guy', yikes

Joey, me too!... I was asked to be an "author".

BlurryBudgie4579, the questions are submitted by regular players like you and I, they asked me once to be a contributor but I declined, too much work

It's always our planet's gravity that truly shapes everything in motion...

I'm afraid of the ocean

if tides were magnetic, your compass would be useless & the ocean could maybe electrocute you ?

fortunately I got the answer to this question correctly. however on the rare occasions that I make an error and choose the wrong answer I get punished. a long commercial for games I am not interested in and horrible music. it's punishment

Kavik.22, my bad

why a lot of babies are born at full moon

surprised to see how many have chosen magnetic

Montana Lady, the moon does not "pull back" to stay in orbit (etc.?) . It's orbit is due to the earth's gravity and the moons orbital velocity.

Montana Lady, and you spelled gist right!

deceptive question...

Its game is so cool in the news a kid die in 2013

I said gravity...it says gravity in the first paragraph.ugh

Yes!! I LIKE THIS. Feels like excited primary school learning.

Flat Earthers said 'Magnetic'.

Shelby Carpenter, it's perfectly explained in General Relativity. There's no force, it's just things doing what you'd expect them to do. Once you've had GR explained, that is. And it's surprisingly simple, too.

What I thought it was momentem

Why does gravity even exist? Without it, there would be chaos in the universe. But what is the intrinsic force present in any object? Where in the mass of an object is it located? It just is. Unexplainable. Weird.

Player #4301819, when did water ever get affected by a magnet?

How come when you go abroad there’s no tides.. In Greece last year the tide never went out why does it in England

I wasn’t thinking right

cant believe so many answered magnetic lol

gamehappy0728, boops

I would add that the reason we don't see tides in lakes and other smaller bodies of water is because the actual gravitational force exerted by the moon and sun on water is very very small compared to Earth. Such that, it's only when you add up all of the tiny tangential forces (angled force lines from Earth to Moon) over the large area of the ocean do you actually get a noticeable tide. Here is a better visual, think of the Moon's gravity as pinching the oceans rather than pulling up on the water. The pinch adds up to a bulge in the middle. Hard to pinch a small area like a lake. As mentioned there are other factors affecting tide height, this is how gravity does. The Earth's spin is constant and would not affect periodicity of tides, only ocean levels.

Roman C. Zuk, the sun also has a effect on tides. Most noticeable when the sun and moon are in alignment on the same side of the earth.
