Ships need more ballast in the ocean because the salt helps keep them a float. So ships need less ballast in the Great Lakes. In the ocean the salt allows the ships to float easier so they might tip on their side, that's why they need ballast, so they don't tip over and the ballast is any substance that acts as a weight and alters buoyancy of a vehicle such as a ship, submarine, or hot air balloon. Such as sand bags on hot air balloons.
Answer:
Marks are painted on the sides of ships which indicates the draught levels to which a ship may be loaded with cargo for varying conditions of season and location. This is called the Plimsoll Mark. The basis is that both salinity and temperature can impact the density of water. There are six loading levels:
Yes, Ocean going vessels are found on the Great Lakes all the time.
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.
It is the St. Lawrence river that links The Great Lakes and the Atlantic Ocean
Great Lakes
It connects the great lakes to the Atlantic ocean by way of the St. Lawrence river.
The Erie Canal linked the Great Lakes to the Atlantic Ocean
There is no such thing as the tlantic ocean.
The Saint Lawrence Seaway is a major waterway that links the great lakes with the Atlantic Ocean.
The Saint Lawrence Seaway is a major waterway that links the great lakes with the Atlantic Ocean.
No. The waterway is a manmade construction along the course of the St. Lawrence River, through which the Great Lakes empty into the North Atlantic Ocean. The waterway's purpose is to deepen the channel for ocean-going vessels and to provide hydroelectric power. The Great Lakes have no natural link to the Mississippi River.
No, South Carolina does not border the great lakes, it is ont the Alantic Ocean
Not directly, but yes: Either by going East through the Great Lakes to the Atlantic Ocean, or by going South via the Mississippi River.
