How high would the sea level rise if all ships and boats were removed ?
Would the planet flood?

Not much
wont the level fall?
think about it. if the boats were taken off the level would fall. think about when you get out the bath!!
Wouldnt it go down?? As when u get out a bath the water goes down..?
If anything the sea level would fall slightly. So small though you couldn't measure it.
not if we left the anchors in
No. The volume of Earth's oceans is so large, that the volume of ships is negligible.
I would imagine that if yu remove something heavy from the water, it would go down and not rise.
The sea level would actually drop, but it would only be a tiny amount, less than a thousandth of a millimeter.
Float something in a glass of water. Note where the water comes to. Now remove the floating object. What happens to the level of the water? It goes down.
If all those objects were removed the sea level would go DOWN not up. If you put something in water it displaces the water causing the water level to rise, remove those objects and the water level would go back down.
No, but imagine if you removed all the sponge living at the bottom of the sea..
How much deeper would it be then?
Water levels would fall!
Every time you put something into water, you displace the equivalent volume of water.
As boats and ships go into the water, theoretically the water rises a miniscule amount. Remove them all, and it would sink back to fill the volume of boats removed.
thats a good question. probably only slightly LOWER though. but there probably is a difference. all these ships may have caused the sea levels to rise and the scientists are trying to blame it on global warming. which is right?
i would have thought it would fall?
The planet wouldn't flood, becasue if you take everything out of the sea, then the level will go down.
Simple logic. You put something into water, and the level gets higher. Why? Because theres more particles there. You take something out, and woah, the water level goes down. There's less particles there.
So all in all, we'd be less prone to flooding than we are now.
If objects are taken out of water, the level will drop, not rise. Take the ice cubes out of a glass of water and you'll see.
nothing will change.. because sea water is not still.. lottz of waves are there so it fluctuates up and down.. and if 70% of earth is covered from water.. how much weight do u think to be thrown into sea to increase its level..
boats and ships displace water, so if you removed them the sea level would fall!!!!
In theory it would go DOWN ! but as the actual displacement of all the worlds shipping is negligible, when put in % terms it would unnoticeable.
Take the density of sea water = w, (it is close to 1, anyway).
A ship floating in the sea would displace a volume of water whose mass will be equal to its mass .
If the total mass of all ships is M, they will displace water of volume
V = M / w
Divide the volume by the surface area of the sea (A), to get the height of displacement:
H = V / A.
The level would fall by this height if all the ships were removed.
(I have assumed that the average density of ships floating in the sea to be greater than that of sea water, fair enough!)
I think the level would drop. Displacement and all that taking place
Guess it would drop. It's all to do with displacement. The planet won't flood because everything that's on it has always been on it and gets recycled one way or another. When I was little I used to think that eventually it would become too heavy because all the people that ever were are still on it as a bag of bones - thus increasing the weight! I'm told now that what's there in bones now, was there before!
...... the level should go down my friend .....
The level would fall!
Ships displace water, therefore if they were all removed to shore the sea level would fall.
no effect
I think the sea level would fall as the boats displace the water pushing it up! But I'm not sure! I guess that it woudn't make much of a difference!
It would drop (Not rise) by such a small amount, that it would be immeasurable.
By a quick calculation here at my desk, using hypothetical figures of displacement, and assuming a perfectly flat sea, and no wind, and no variances in lunar gravitational pull to produce adnormal tides..
It would drop by the distance of one-tenth of the width of an atom.
No, the planet would not flood.
Does this help?
the sea level would fall by the weight of water by which the boats are displacing, so basically how ever much all the boats in the world weigh, the same weight in water would be required to fill all those holes in the sea left by the boats, causing the sea level overall to fall
I cannot for the life of me find the mass of all boats and ships in the world (it is I would guess a nearly impossible and immensely time consuming task).
the amount by which the global sea level would fall is fairly negligible, if at all noticeable, if you think that the world has an area of 361 million sq km covered by oceans it is unlikely that there are to be major changes
hope this helps
Saw this answered in a magazine recently, though I can't remember which, sorry. The basic gist was sea level would rise by some 0.025% if all the world's shipping was removed. Which is a very small amount indeeed. Don't lose any sleep over it!
