It was more economical to transport the ingredients for steel to centralized plants rather than to make steel on the spot. It is 350 miles (563 km) long (east to west), and at its greatest width it is 160 miles (258 km) from north to south. About 10,000 years ago, the upper lakes evidently discharged through this area via the Ottawa River valley, and their levels were substantially reduced. Only barges can access the Illinois Waterway system providing access to the Gulf of Mexico via the Mississippi River. Earth Science Stack Exchange is a question and answer site for those interested in the geology, meteorology, oceanography, and environmental sciences. [76], Scientists understand that the micro-aquatic life of the lakes is abundant but know very little about some of the most plentiful microbes and their environmental effects in the Great Lakes. [50], The total surface area of the lakes is approximately 94,250 square miles (244,100km2)nearly the same size as the United Kingdom, and larger than the U.S. states of New York, New Jersey, Connecticut, Rhode Island, Massachusetts, Vermont, and New Hampshire combined.

The lakes drain roughly from west to east, emptying into the Atlantic Ocean through the St. Lawrence lowlands. Mercury compounds have been used in paper mills to prevent slime from forming during their production, and chemical companies have used mercury to separate chlorine from brine solutions. Thanks for contributing an answer to Earth Science Stack Exchange! Members; 912 December 23, 2007; [125] A few small cruise ships operate on the Great Lakes including some sailing ships. Because of their sea-like characteristics, such as rolling waves, sustained winds, strong currents, great depths, and distant horizons, the five Great Lakes have long been called inland seas. When a second fault line, the Saint Lawrence rift, formed approximately 570million years ago,[14] the basis for Lakes Ontario and Erie was created, along with what would become the Saint Lawrence River. [80] Discharge of toxic substances has been sharply reduced. Most lakes support a lot of aquatic life, but not all. [66] By 1938, Wisconsin's commercial fishing operations were motorized and mechanized, generating jobs for more than 2,000 workers, and hauling 14million pounds per year. Ontario is the most tightly regulated, with its outflow controlled by the Moses-Saunders Power Dam, which explains its consistent historical levels. [70][needs update], The alewife first entered the system west of Lake Ontario via 19th-century canals. Why the Great Lakes are Better than the Ocean The immigration routes still have an effect today. The Great Lakes system includes five large lakes, one small lake, four connecting channels, and the St. Lawrence Seaway.

As the anti-depressant drugs pass out of human bodies and through sanitation systems into the Great Lakes, this has resulted in fish in the Great Lakes with twenty times the level of anti-depressants in their brains than what is in the water, leading to the fish being exceedingly happy and hence less risk-averse, to the extent of damaging the fish populations. There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the CanadaUnited States border. about 500 km of non-tidal flow below the outlet of Lake Ontario, New blog post from our CEO Prashanth: Community is the future of AI, Improving the copy in the close modal and post notices - 2023 edition. janetcbl.
