seaway
body of land with water on three sides
with oil, feaces, other nasty things... depends on the ship.
Ships don't sink in the ocean because the air pressure pushes the ship upward and keeps it buoyant-------------------------------- Ships don't sink because the overall density of the ship is lower than the density of the salt water and it displaces its weight's equivalent of water using only a portion of the ship's volume.
First off, it's not just factories. Ships, cities, bad agricultural practives, dumping, air pollution and other factors are polluting the ocean. All this in conjunction with the impacts of global warming. If the contamination of the seas continues, an impact on fish stocks and the general health of the ocean ecosystems will certainly occur.
Antarctica was the last continent on earth to be discovered, because discovery transport was based on sea-going ships which could not survive a collision with an iceberg.
inland waterways:Inland waterways include transport through navigable rivers and canals.ocean routes:Navigation along the coastal places and foreign countries take place with the help of ships.
There are about 80,000 ocean-going ships in the world.
Your question is missing a word.
Ocean-going ships can travel from the Atlantic Ocean to Duluth Minnesota through the St. Lawrence Seaway, which is a series of canals, locks, rivers and lakes that is the world's longest inland waterway that can handle ocean-going vessels. In 1959 President Dwight Eisenhower and Great Britian's Queen Elizabeth II formally opened the Seaway. The maximum allowed ocean-going vessel size is 740 feet (225.6 meters) long, 78 feet (23.8 meters) wide and 26 feet (7.9 meters) deep. Only 10% of ocean-going ships may travel the entire length of the Seaway.
The St Lawrence Seaway permits large ocean-going ships to load and unload at inland ports such as Thunder Bay and Chicago, thus reducing transportation costs.
because they were going across an ocean
The Panama Canal connects the Atlantic and Pacific Ocean. It was created to shorten trips of ships.

Seismic waves moving through the ocean do not form tsunami's until they approach land. At that point the forward motion of the waves pile up on the land and form a series of forward flows that do not have an opportunity to recede due to the following waves. As a result, the waves keep coming on top of the previous waves and come farther inland. Ships at sea do not notice the tsunami until they are over the continental shelf.
so ships can get from the pacific to the Atlantic or vice versa, without having to travel around the continents
