The discovery of Lake Vostok led scientists to ask many questions. How did the lake form? Does anything live in the lake? If so, what lives in the lake? How could living things survive in this environment?

What lies beneath 2.3 miles (3.7 km) of ice? What covers an area of roughly 5,400 square miles (13,985 sq. km)? What is around 30 million years old?

Answers

Answer 1

Answer:

See explanation

Explanation:

Subglacial Lake Vostok is a lake occupying a topographic hollow beneath the Antarctic Ice Sheet. Water occurs at high pressure beneath the Antarctic Ice Sheet and accumulates in topographic hollows. This hollow may have formed during pre-glacial or glacial times and is tectonically controlled. There were organisms known for living in salt water, fresh water, super-hot water and even in the guts and other body parts of tube worms, fish and other animals. There were low amounts of genetic material that appeared to come from animals such as a microscopic crustacean, a marine bivalve and a small sea anemone.  Almost 4 km beneath the East-Antarctic ice sheet, Lake Vostok, a vast freshwater lake was discovered 1996 by using ice-penetrating radar and artificial seismic waves. Lake Vostok is the oldest, most pristine lake in the world and it never has been disturbed by humankind yet. It is one of more than 70 lakes, which have been identified under the Antarctic ice sheet. Scientists estimate Lake Vostok''s age at 35 million years.

Every economic system is theoretical. As a result, these systems do not account for the intricacies of the real world. In theory, a command economy promotes fairness and equal distribution of wealth. In reality, its framework cannot account for greed or unchecked power by those in charge. Similarly, a market economy lends itself a winner-take-all attitude. In reality, there is usually a practical need to support members of society who need financial assistance. Because of this, the vast majority of economic systems around the world are mixed economies. The term mixed economy represents a wide spectrum of economic systems. Because capitalist countries like the United States offer publicly-funded social programs and communist countries like Cuba recognize private property, neither country can be considered a purely market or command economy.
