Knowledge of the geography of the Great Lakes in the United States.

The Great Lakes are several large freshwater lakes located on the border between Canada and the United States, from largest to smallest: Lake Superior, Lake Huron, Lake Michigan, Lake Erie, and Lake Ontario. With the exception of Lake Michigan, which belongs to the United States, the other four lakes are shared by Canada and the United States.

The Great Lakes are formedThe basins of the Great Lakes are mainly formed by glacial erosion. During the Quaternary Ice Age, the Great Lakes region was close to the glacial centers of the Labrador and Kivadine continents, and the ice sheet was 2,400 meters thick and extremely erosive. When continental glaciers retreat, ice water accumulates in glacial depressions, forming the surface of the Great Lakes.

The Great Lakes of North America is the world's largest group of freshwater lakes, that is, the general name of five connected lakes in North America, including Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario, also known as the Great Lake, known as the "Mediterranean Sea of the North American continent". Except for Lake Michigan, which belongs to the United States, the other four Great Lakes in North America all cross the United States and Canada. The Great Lakes have a total area of 10,000 km2, of which 72% are in the United States and 28% in Canada.

The total water storage capacity is about 22.8 trillion m3, accounting for about 1.5 of the total number of freshwater lakes in the world.

Do you know how to get to the Great Lakes of the United States? Ice Age Ice Ages once covered half of the United States.

The five great lakes in the United States are Lake Superior, Lake Huron, Lake Michigan, Lake Erie, and Lake Ontario.

1. Lake Superior

Lake Superior is the world's largest freshwater lake, discovered by French colonists in 1622. The lake is shared by the United States and Canada and is surrounded by the Canadian province of Ontario and the American states of Minnesota, Wisconsin and Michigan.

2. Lake Huron

Lake Huron, the second largest lake in North America's Great Lakes, is located in the middle. Shared by the United States and Canada. It stretches from northwest to southeast, is 330 kilometers long, and is 295 kilometers wide at its widest.

With an area of 10,000 square kilometers, it ranks second among the Great Lakes. The lake is 177 meters above sea level. The average water depth is 60 meters, and the maximum depth is 229 meters.

The water storage capacity is 3,540 cubic kilometers. The shoreline of the lake is 2,700 kilometers long and winding, with the Bay of Georgia to the northeast.

3. Lake Michigan

Lake Michigan, also known as Lake Michigan, is the third largest of the five Great Lakes in North America and the only lake that belongs entirely to the United States.

The coast is lined clockwise from the south to the following states of the United States: Indiana, Illinois, Wisconsin, and Michigan. The total area of the lake is 57,757 square kilometers, with an average depth of 84 meters. The climate of the lake area is mild, and most of the lakeshore area is a summer resort.

The east coast is rich in apples, pears and other fruits, the south bank is straight, the north bank is curved, and there are many good harbors.

4. Lake Erie

Lake Erie is shared by the United States and Canada, with the United States to the east, west, and south, and Canada to the north. It is west-southwest-east-northeast. It is 388 kilometers long from east to west and 92 kilometers wide at its widest.

With an area of 10,000 square kilometers, it ranks fourth among the Great Lakes, only larger than Lake Ontario. The lake is 174 meters above sea level, which is 99 meters higher than Lake Ontario. With an average depth of 18 meters and a maximum depth of 64 meters, it is the shallowest in the Great Lakes.

The water storage capacity is 455 cubic kilometers. The total length of the lake shoreline is 1,200 kilometers, which is relatively straight, and there are few lakes and bays.

5. Lake Ontario

Lake Ontario is the world's fourteenth largest lake, bordered by Ontario, Canada to the north, the Niagara Peninsula to the south, and New York. It is one of the five largest freshwater lakes in North America and belongs to the largest group of freshwater lakes in the world.

The name "Ontario" comes from the Iroquois word skanadario, which means "lake of beauty" or "lake of glitter", from which the Canadian province of Ontario got its name.

The Great Lakes is the largest group of freshwater lakes in the world. Located in east-central North America, between the United States and Canada, the general term for five lakes connected and communicating with each other, they are: Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario.

The Great Lakes are the largest freshwater bodies in the world, with a total area of 245,660 square kilometers, and are located in the middle of the North American continent, so they are known as the "Mediterranean Sea" or "Freshwater Sea" due to their huge volume of water and their location in the middle of the North American continent.

Lake Superior is the most northwestern and largest of the Great Lakes in North America, one of the largest freshwater lakes in the world, and the second largest lake in the world after the Caspian Sea.

Lake Huron is the second largest of the Great Lakes in North America, and it stretches from northwest to southeast.

Lake Ontario is the easternmost and smallest of the Great Lakes in North America, bordered by Canada to the north and the United States to the south.

Lake Erie is the fourth largest lake of the Great Lakes in North America, with the United States to the east, west and south, and Canada to the north.

Lake Michigan is the third largest of the Great Lakes in North America and the only lake that belongs entirely to the United States. It runs northeast and southwest, and the north of the lake is connected with Lake Huron.

1.The Great Lakes of North America were formed 7,000 to 32,000 years ago by the retreat of glaciers in the Pleistocene.

2.Before the Pleistocene glaciation, the Great Lakes were east-west water systems.

3.During glaciation, glaciation widened and deepened river valleys.

4.During the third glacial retreat of the Pleistocene, the south bank of the area left terminal moraine ridges, and the lower reaches of the St. Lawrence River were still covered by glaciers.

5.??Lake Erie is thought to have reached its present size about 10,000 years ago, Lake Ontario was formed 7,000 years ago, and the other three lakes were formed 3,000 years ago.

6.The elevation of the lake descends in a stepwise manner from west to east: the difference in water levels between Lake Superior and Lake Huron is 7 meters, forming the St. Marys River with many rapids.

7.Lake Michigan and Lake Huron are at equal water levels and are connected by the Mackinac Waterway.

8.The difference in water levels between Lake Huron and Lake Erie is 2 meters, and the St. Clair River Rapids is formed in between.

9.Lake Erie Tights Lee is 99 meters higher than Lake Ontario, forming the Niagara River Rapids halfway through it with a drop of 50.

10.??Niagara Falls, the world-famous waterfall of 9 meters, the third lake enters the St. Lawrence River through the mouth of Lake Ontario and then flows into the St. Lawrence Bay in the Atlantic Ocean.

11.The deepest is Lake Superior with a maximum depth of 406 meters.

12.The shallowest is Lake Erie, with a maximum depth of only 64 meters.

13.The maximum depth of the remaining three lakes is above 200 meters.

14.The lake is fed mainly by precipitation and receives many small rivers, with an average annual flow of 6,640 cubic meters per second at Lake Ontario into the St. Lawrence River.

15.??Water levels are higher in summer and lower in late winter and early spring.

16.The water temperature of the lake is 16 21 in summer, below 0 in winter, and the ice period is more than 4 months.

17.The Great Lakes have a significant regulating effect on the climate of the surrounding lake area, making it mild and humid with a long frost-free period, which is conducive to agriculture.

18.Agriculture, forestry, fruit and fishery are all very developed, and it is the main concentration area of inland fisheries in North America, mainly producing lake trout, white fish, lake herring and so on.

Lake Superior is the most northwestern and largest of the Great Lakes in North America, one of the largest freshwater lakes in the world, and the second largest lake in the world after the Caspian Sea.

Lake Huron is the second largest of the Great Lakes in North America. It stretches from northwest to southeast, is 331 kilometers long, and is 163 kilometers wide at its widest point.

Lake Michigan, also known as Lake Michigan, is the third largest of the five Great Lakes in North America and the only lake that belongs entirely to the United States.

Lake Erie is the fourth largest lake in the Great Lakes of North America, bounded by the United States to the east, west, and south, and Canada to the north. The lake covers an area of 25,667 square kilometers.

Lake Ontario (Ontario, lake) is the easternmost and smallest of the Great Lakes in North America, with Canada to the north and the United States to the south, roughly elliptical in shape, with a main axis of 311 kilometers from east to west and 85 kilometers wide at its widest point.
