My America. Great lakes – the largest lake of the world all together contain less water than the lake – VOICES MY AMERICA
Great lakes (Fig. Great Lakes, FR. Grands Lacs) — a Grand natural system of freshwater lakes in North America, in the U.S. and Canada. Includes a number of large and medium-sized reservoirs, connected by rivers and Straits. An area of about 245,2 thousand km², the volume of water is 22.7 thousand km³.
To actually five Great lakes include the largest: Upper, Huron, Michigan, Erie and Ontario. They are associated with several medium-sized lakes, the most important of which are the St. Marys, St. Clair, Nipigon. These lakes belong to the basin of the Atlantic ocean. Stoke on the St. Lawrence river. On the formation of lake basins are significantly influenced by tectonic processes. The weight of the glacier pushed the earth’s crust, and after the glacier melted away, she slowly began the process in reverse: post-glacial uplift, which is also very noticeable in the area of the Gulf of Bothnia and Finland. The water mass of lakes formed by the melting of the glacier. North coast Great lakes South rises faster, which leads to the effect of “transfusion” water and slow the flooding of land in the South.

The surface of the lake supple and oily, if you try to “scoop up” his “water,” she pulled thick strands of tar. This lake cannot be called a fixed – it passes its life, however, very similar to life in other lakes.
In the depths of the Peach lake always something bubbling. And here on the surface of the slowly diverge to the shore from the center of the strange thick waves, when a new piece of tar rises from the depths. Or it suddenly starts to bubble – up to the surface from the depths of sulfurous gases.
The lake is known since ancient times. Even Walter Raleigh, English Navigator and organizer of the pirate expeditions of the sixteenth century, used local asphalt to cover the hull Continue reading
