Why finland is having a great number of lakes?How are they formes?
Answers
Finland became a country with an extraordinary amount of water in it because of geological conditions that pre-date the creation of the state by many thousands of years. Although there are no glaciers in Finland now (despite a substantial portion of the country being located in the Arctic Circle) the effects of glaciation can be seen in the geography and lake formation in Finland in the present day. During the last major period of climate change continental glaciers covered a vast majority of what is now considered to be the country of Finland. Approximately 10,000 years ago the glaciers began to melt and left behind physical evidence of their presence in the forms of mountains, valleys, depressions, and fields of glacial mineral deposits.
As we know glaciers are very powerful. Glaciers have the ability to dramatically change how a landscape looks as they are formed, as they slowly move and grow, and then when they recede and melt. Glaciers have helped create some of the most extraordinary landscapes in the world that continue to stun viewers tens of thousands of years after the glaciers themselves have been forgotten.
The glaciation in Finland was a huge factor in the creation of the lakes that exist today. The sheets of ice moving across the surface of the Earth created divots, gouges and craters that filled up with melted waters after the glaciers receded. These lakes are still changing and evolving as drainage patterns continue to be formed around the country and as erosion takes its toll on the physical landscape through water, wind, and chemical changes.
