The sea level dropped, exposing continental shelves. During this glacial period, scientists say that sea levels were perhaps 100 meters (330 feet) lower than they are today. The continental shelves between North America and Asia were probably exposed during the Ice Age.
During this glacial period, scientists say that sea levels were perhaps 100 meters (330 feet) lower than they are today. The continental shelves between North America and Asia were probably exposed during the Ice Age. Some scientists say that the shelves provided a “ land bridge ” between the two continents.
Some 18,000 years ago, at the peak of the most recent ice age, much of the Earth’s water was frozen into huge masses of ice called glacier s. The sea level dropped, exposing continental shelves. During this glacial period, scientists say that sea levels were perhaps 100 meters (330 feet) lower than they are today.
According to the UN Convention on the Law of the Sea, every nation has a continental shelf extending no more than 200 nautical miles from the nation's coastline. A lot of fuel we use is collected from beneath the continental shelves.
