why there are thousands of lakes in finland
Finnish Lakeland The lake basins of the lakeland originate from the joint work of weathering and erosion of fractures in the bedrock. The erosion that made the depressions occurred before and during the Quaternary ice ages.[1] Erosion along fractures has produced linear inlets among the lakes.[2]
Lake Ontario Lake Ontario (French: Lac Ontario) is one of the five Great Lakes of North America. It is surrounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the American state of New York, whose water boundaries meet in the middle of the lake. Ontario, Canada's most populous province, was named for the lake. In the Wyandot (Huron) language, ontarío means “Lake of Shining Waters”. Its primary inlet is the Niagara River from Lake Erie. The last in the Great Lakes chain, Lake Ontario serves as the outlet to the Atlantic Ocean via the Saint Lawrence River.
