What liquid makes ships lower?
Ballast tanks contain water, usually sea water.
What is main ballast of a vessel?
Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.
Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
Are marbles useds for ships ballast?
yes
What is the ballast of a ship usually made of?
Ballast on smaller vessels is often water,high density materials like concrete or iron or just the weight of the crew. On larger vessels such as container ships,it is a combination of water and cargo.

How was the round goby brought into the US?
Ballast water in cargo ships, brought over from the Black, Caspian, Marmara, and Azov seas.
What affects the weedy sea dragon?
1: Ballast Water- because if you look at the mum clues (scientific questions) go to page 11 and go to the one about the fungus, it will say it is found in ballast water. They release the water because when they dont have cargo (the ships) they pump water in the water tanks, but when they have cargo, they let go of the water
What is a center tank on ships?
Big ships have ballast tanks to do two things: allow an unloaded or lightly loaded ship to ride lower in the water, and to change the way the ship rides in the water. The center tank is there to adjust ride height.
Why are zebra mussels located primarily in areas in the eastern US rather than in the western US?
It is generally agreed upon by scientists that zebra mussels entered the Great Lakes from ballast water dumping by large ocean-going vessels from Europe. Ballast water is used to keep ships stable in the water.
What is the ballast on a boat?
Weight used to keep the boat stable in the water. Old seagoing vessels, such as pirate ships use to have ballast stone which was kept in the bottom of the boat down the middle(keel) to keep the boat sitting properly in the water. Modern submarines use saltwater in their ballast tanks(big huge tanks located inside the hull) to enable them to sink and remain submerged
What were ships ballasts used for during World War 2?
When the ship is empty it rides very high in the water, bobbing around like a cork. This is unstable and uncomfortable for the crew. Ballast - sea water - was usually taken on, in special built-in tanks just inside the hull of the ship, to make the ship heavier, so it would ride lower in the water and be more stable. In olden times sailing ships used rocks for ballast.
