Karelia is often called the land of lakes and rivers. The abundance of freshwater bodies, it is much superior to other areas of the Soviet Union and such foreign countries as Finland, Sweden and Canada, also famous for its abundance of lakes. On the territory of Karelia over 60 thousand big and small lakes with a total area of over 42 thousand square km, including the largest lake in Europe — Ladoga and Onega.
Only one third of the Karelian lakes — waste, the other ows have. Closed to include numerous forest ponds, usually with peat marshy shores, called Lambada. Large, medium and small lakes are part of the flow and often form lake-river systems, connected by rivers and canals. The flowage lakes is a positive one for living in them fish, because it reduces the likelihood of a fish kill caused by lack of oxygen in water in the winter.
The depth of the lakes that are important in fish life is quite varied. The greatest depths are typical for large lakes: Ladoga (260 m), Onega (120 m), Segozero (97 m). On small lakes depths usually do not exceed 3-5 m Deep places often alternate with underwater rocky bottom or shoals, called Lud.

Our planet consists of many unique places which you can enjoy forever. These masterpieces of nature can be called many lakes, especially those to which people have not had time to take a hand.
According to statistics, on Earth there are about 5 million lakes. They are all different in origin, shape, size, composition, water depth, etc. because the lake is a closed basin, they are literally tanks for experimental mixes. They can happen strange chemical reactions, but also to emerge of abnormal create, which you will not find anywhere else.
Some lakes are places of catastrophic events in history, such as falling meteors or volcanoes while others keep the ancient secrets or unique geological formations.
Today we present to our readers the most unique lakes on the planet Earth.
1. Spotted lake
In the canadian province of located the exclusive lake called Spotted thanks to some features that have no analogues in the summer season the water in the pond dries up, and instead there is a variety of colored puddles. Their hue was subject to the type and saturation of minerals.

Recently, researchers at brown University decided to conduct an unusual study and calculate how much water could be near the Martian volcano Arsia Mons. According to them, the heat of a volcano under a huge glacier in the relatively recent past contributed to the formation on the red planet, large lakes filled with water. And as you know, where there’s water, there may well be life.
According to the researchers, in the recent past, Arsia Mons, a volcano on Mars may have been the source for the existence of life. Scientists found that the glacier was located at the foot of the volcano. This is indicated by the grooved area in the foreground. According to experts, the eruption occurred on the territory of the ice cover, so in the end, the melting ice may form lakes of liquid water.
It should be noted that Arsia Mons is the tallest volcano on the red planet, and also one of the largest mountains in the Solar system. Its height exceeds the height of mount Everest almost twice. In the recent past the slopes of this giant volcano on Mars covered monolithic ice.
The analysis of the topography of the volcano, scientists have found that 210 million Continue reading
