Would all the seas rise? It's not important, it's just a random thought that popped into my head when I was out cycling earlier.

And coming to that, what if you take an oil tanker out.

Yes, I'm bored...

It would rise locally. Yes if it was liquid to the nth degree, it would rise the world round by an infinitessimal amount. But at the end you have discrete atoms. so you can't have the same volume of water rise and be spread 10000km x 10000km x 0.00000001atoms.

I've always wondered about the net weight of the Earth, what with all the garbage we're firing into space...

Did you pick the pebble from the shore?

But then there's all the dust that comes back in from space.

it'll improve signal to noise

No.

When you throw a pebble in the sea it splashes water up into the air. This splash will evaporate and as it will be the same displaced volume as the pebble the sea level will remain exactly the same.

Unless (as chaos thery suggests) the disturbance of the pebble splash causes a far away albatross to exit the sea, in which case the sea level will reduce. Possibly a substantial decrease depending on the size of the Diomedeidae. This is obviously a real albatross not some sort of Coleridgeesque metaphor.

Unless the pebble gets swallowed by a fish before reaching the sea bed in which case all hell will break loose.

It would indeed drop. Therefore, using some logic, we can all do our bit for rising sea levels by not using boats and flying instead.

Um. I think.

What about the big hole in the sea bed that the oil comes out of, does that fill up with sea water?

It would not rise, amazingly.

The reason ?

Due to the world warming slightly, evaporation would be such that the reduction of overall water on the planet in the sea would out weigh the insignificant rise caused by the pebble.

Little known fact that one of the most significant potential threats to the rise in sea levels comes from the dual impact of the rise in sea temperatures killing off the worlds sponges and when these die they will release all the water they hold back into the oceans.

It's anticipated this could contribute a rise of some 2 to 4 metres of water level.
