Q. Consider the following statements with reference to the Labrador Sea:
1.It is a marginal sea of the North Atlantic Ocean bounded by the Labrador Peninsula to the west and Greenland to the northeast.
2.It was formed due to the geological separation of the North American Plate and the Greenland Plate.
3.It contains the Northwest Atlantic Mid-Ocean Channel, which is one of the world’s largest turbidity current channel systems.
How many of the above statements are correct?
Answer: C
Notes:
Explanations:
- Statement 1 is correct: The Labrador Sea is a northwestern arm (marginal sea) of the North Atlantic Ocean. It lies directly between Canada’s Labrador Peninsula and the island of Greenland.
- Statement 2 is correct: Geologically, the Labrador Basin formed as a failed rift arm during the broader North Atlantic tectonic breakup. The basin opened due to the separation of the North American Plate and the Greenland Plate, a process that started approximately 60 million years ago.
- Statement 3 is correct: The Labrador Sea houses the Northwest Atlantic Mid-Ocean Channel (NAMOC). It stretches thousands of kilometers and is one of the world’s largest deep-sea turbidity current channel systems
