Unleavened pond with the largest area - it Upper Lake.Location - North America.82.4 thousand sq. Km covers an area of its water surface.The lake is located on the 3rd place in terms of fresh water on the planet, and it is inferior in terms of only Lake Baikal and Tanganyika.The content of fresh water in the lake is 11.6 thousand. Km3.Average depth - 147 m, the highest - 406 m.
Great Lakes
Where is Lake Superior on the map of the North American continent?It is situated on the territory of the United States and Canada.Lake Superior - is one of the Great Lakes, link in the chain of freshwater bodies, which are located in the east of North America between Canada and the United States.The system consists of five lakes: Superior, Huron, Michigan, Erie and Ontario.Only Michigan is wholly owned by the United States.
other lakes are separated by the border.In Canada, Lake Superior is located in the province of Ontario.On the western shore of the lake is Minnesota.On the southwest - Wisconsin.South Coast is located in Michigan.
coastline - 4387 km.The length of the lake - 560 km.The maximum width is 260 km.The coastline is indented bays and gulfs.On the north shore - cliffs and rocks.A south coast has a level ground.
Links
Upper Lake is the second largest on the globe, and, as already mentioned, the largest freshwater bodies in the world and the United States.It ends the way from the Atlantic Ocean into the continent.All of the Great Lakes are connected to each other by rivers and canals.Top inextricably linked with Lake Huron River St. Marys, the length of which is about 112 km.It has a large number of rapids and shoals in these places, it is not suitable for navigation.It is because bypassing thresholds established channels.Lake Superior has been reported with the Canadian Lake Nipigon by a small river.
Occurrence
Bowl lake looks like depressions of tectonic origin.Because of the large number of earthquakes appeared deep faults.The bottom of the lake lined glaciers, earthquakes finish the job thing.According to scientists, about 30 thousand years ago, North America in the eastern part was covered by glaciers, who came here from the north.These glaciers are unstable.They are then shifted to the north, leaving a lake bowl, then come back here.When the glaciers finally left the territory of the eastern regions of the continent, at this point it formed a huge lake that has received in the name of modern science Algonquin.By area, it was very large and presumably exceed the size of the lake 10 times.This lake existed long.After a while, it took a lot of water that filled the St. Lawrence River.A few thousand years on this place appeared the Great Lakes.
uniqueness
These famous lakes are considered one of the great wonders of the world.They are unique.Lakes form the hydrographic community, and very extensive, different from the rest of the world's lakes size, volume of water and the configuration of the coastline.They are 500 miles from the Atlantic Ocean and 700 km from the Hudson Strait.They represent the largest lake system in North America, located in the upper and middle parts of the St. Lawrence River Basin.
«Sea Road»
Great Lakes - one of the main shipping routes in eastern North America.To reach the port of Duluth on Lake Superior to the source of the St. Lawrence River, the way to overcome more than 2000 km.Most Alpine Lake Superior - 183.6 meters above sea level.Pond fed by precipitation and water, which are the river.
Lake Superior a drain or undrained?
try to sort out this issue.The lake is a drain, its drain occurs through the St. Marys River.From December to April in the coastal areas of freezing occurs.The water level in the lake drops.Precipitation is also rare in this time, because a sufficient volume of water to maintain the level of the lake is not received.
minimum level is usually in March or April.Then, the ambient temperature rises and coastal snow begin to melt.Rivers quickly filled with water, and this leads to an increase in its level in the lake.
largest volume of water in the upper observed in the summer, just at this time are heavy rains.Fluctuations in the level is less than 1 m, but sometimes it's more.This happens largely due to the influx of water, but because of the movement of air masses.
Seishi
Lake Superior is not protected by mountain ranges, so the winds that come from the mainland or from the ocean, freely roam, becoming a cause of unrest in the pond.
where you can observe the frequent phenomenon for this place - seiche.Giant wave formed on the surface of the lake, leading to the collapse of the bank.Lake Superior colder than the rest of the Great Lakes.In summer, the water warms up no more than 12 degrees.And it is almost always a depth of about 4 degrees.
Power
lake in Lake Superior falls more than 200 rivers.Nipigon - one of them, it is the length of 48 km and a width of 50 to 200 m. It is impossible not to recall the river St. Louis, whose length is 192 km.Another flow rivers such as Pidzheon, Brule, white, rocky.All of them are no more than 100 km long, but still contribute to food lake.
Islands
Lake Superior has the island, some quite large.The biggest - Isle Royale, it reaches a length of 72 km, width - 14 km.On the Great Lakes, he ranked 2nd after Manitoulin Island in Lake Huron.Who is Isle Royale National Park status, which ferries from the mainland.
the north of the lake is an island Mishipikoten, its length - 27 km, width - 10 km.It is the realm of wild nature.22 islands, bearing the name of the Apostle Islands belong to Wisconsin.
also call the island, which is a national recreation area in Michigan.It Madeline and Grand Island.
Conclusion
Near the lake there are many major cities such as Duluth, Thunder Bay, Marquette, Sault Ste Marie.In this article, you learned where Lake Superior.Read about the history of its occurrence.We meet interesting facts, its location on the map and get other information.We hope you have been interesting.
