Because the boat has a special shape that makes it less dense than water.
a big heavy steel ship floats on water because the volume is mostly air. trust me its true.
Because big density is to heavy.
The size of the boat is equal to the water displaced by the boat. This means, if the boat is bigger then its weight, the boat will float. If the boat is smaller than its weight, it sinks. This is why metal ships are so big.
Shipbuilders chose coastal locations because ships are too heavy and big to be carried to their home in the water by any other means. The ships are mostly built on a framework on land and then slid right into the water.
Objects denser than water will sink; objects less dense than water will float. Since aluminum metal has a density of around 2.7 grams per cubic centimeter and water has a density of 1.0, a solid block of aluminum would sink.
I think you've shortened your question a bit too much for clarity. Why heavy ships are still able to float is often explained by saying that they are able to push away enough water to equal their own weight. It's all down to OVERALL density. Things that have a higher density than water sinks, and things that have a lower density than water floats. Now, water has no clue to the density of the material, it can only react to the overall density of the complete item. So if you take a heavy material, but turn it into a big, thin-walled container, the overall density of that container can still be less than that of water, and the contaienr will float.
it will get a big storm
That would be Saturn, since it lacks in density it would be light enough to float in an ocean big enough for it.
Saturn. And then the water freezes...
Saturn would float in water if you could find a big enough tub and the water to fill it.
Nobody, it just exists.Most of the deuterium in heavy water was produced in the big bang, with a small percent produced in long dead stars.
It is incorrect to say that heavy objects sink in water because... A big slab of wood is heavy, right? Wood floats. For one example.
