Geologists, researchers and scientists agree that some lakes have existed for millions of years. These special lakes are discussed in the next article.
The oldest lakes in the world
Lake Zaysan in eastern Kazakhstan is believed to have originated in the Cretaceous, about 65 million years ago. It is the oldest lake in the world, although its exact age is controversial and cannot be determined. The freshwater lake covers an area of about 700 mi² and is located between the Tarbagatai and Altai mountains. The lake is frozen between November and the end of April.
Lake Baikal in southern Siberia was founded 25 million years ago. Unlike Lake Zaysan, researchers are more unanimous about their age and are commonly referred to as the oldest lake in the world. The freshwater lake covers an area of approximately 12,248 square kilometers and is the largest freshwater lake in the world. It has an average depth of 2,442 ft and holds 23% of the Earth’s fresh surface water.
Lake Tanganyika in East Africa is the second largest freshwater lake in the world. It was formed about 9 million years ago. It covers an area of approximately 12,700 square kilometers and has an average depth of 1,870 ft, making it the deepest lake in Africa. It contains about 4,500 cu of water, which is about 16% of the surface water on earth.
The Caspian Sea, located between Europe and Asia, is the largest lake on earth with an area of approximately 143,200 square kilometers. It contains 18,800 cu of water. It has a salinity of 12 g / l, which is one third of sea water. It exists about 5.5 million years ago.
Lake Biwa in Shiga Prefecture is the largest lake in Japan with an area of 258.8 square miles. It has a maximum depth of 341ft and holds 6.6 cu of water. The lake has been around for 4 million years, making it the oldest lake in Japan and the oldest lake in Asia.
Lake Ohrid, located on the border between eastern Albania and southwestern Macedonia, has existed for the past 3 million years. It covers an area of 150 square miles and has an average depth of 509 ft. It is the deepest lake in the Balkans, with approximately 13.31 cu mi.
Lake Lanao in the province of Lanao del Sur in the Philippines has existed for more than 2 million years. It covers an area of approximately 120 square meters and is the second largest lake in the Philippines after Laguna de Bay.
Lake Malawi in Africa has existed for the last 40,000 years. It is the ninth largest lake in the world with an area of approximately 11,400 m² and an average depth of 958 ft. The lake contains 2,000 cu of water.
The importance of ancient lakes.
Scientists are studying ancient lakes to determine the mechanisms of environmental change over time. These lakes preserve history, including adaptive radiation and sexual selection by organisms that, due to their geographical isolation, provide unpolluted data.
