largest store of fresh water on the planet Earth



Lake Baikal is not only the volume lake.It is the deepest and one of the most ancient.Lake Baikal is the deepest in the cleft on the surface of the planet.This chasm - the most complex and least understood area of ​​crustal faults.The depth of the lake is on average 745 meters, and the deepest point reaches 1637 meters.The lake stretches for 636 km and its width is 80 km.The lake surface is 31 000 km2.

This ancient lake appeared 20-30 million years ago as a result of tectonic shifts.Fresh and clean water in the lake is maintained by two factors.Firstly, it inhabits endemic Baikal epishura - microscopic crustacean, filter a huge amount of algae and bacteria.In addition, a large part of the watershed of Lake Baik
al maintained rocky rocks.Thus, the flow of water on the way to the lake is almost in contact with the sediments and minerals.It oligotrophic lake, and the water in it has excellent drinking quality.

into Baikal 365 rivers, including the Yenisei River - the largest river in Siberia.The lake contains 20% of the stock of fresh water on the Earth's surface.The volume of fresh water in the lake is 26 000 cubic kilometers.The ancient pond is considered one of the cleanest in the world.The water extracted from the depths of the lake, you can drink without pretreatment.In winter the lake is frozen and covered with ice.

most oligotrophic lake in the world



Lake Superior, referring to the system of freshwater lakes in North America, is the biggest water surface freshwater lake in the world.Its surface covers 82,170 km2.It contains as much water as all the Great Lakes combined: 11,600 cubic kilometers.Fresh water of the lake is 10% of the total stock on the surface of planet Earth. With Lake Superior connected rare natural phenomenon - a lake-effect snow when the winter cold air over the warm surface of the water saturated vapor turns into clouds and then precipitation falls as snow.

amounts of water in the lake is enough to flood the North and South America at a depth of 30 cm. The deepest mark in the lake is 400 m. Lake Superior is drained more than 300 rivers and streams.If

stretch shoreline of the lake in a straight line, it would connect the Bahamas and Duluth, a town in Minnesota, USA.

The average water clarity in the lake reaches a depth of 8 meters.This is the most clean and clear of the Great Lakes and the most oligotrophic lake in the world.The length of the lake is 563 km and width of 257 km.In the summer sun on the western shore of Lake rolled up 35 minutes later than its southeastern shore. biggest area lake in the world - the Caspian Sea.But it is not a freshwater.The salinity of the water there is about a third the salinity of water in the seas of the planet.

Lake Superior - one of the youngest lake in the world.He was only 10 000 years.
