Q. Consider the following statements:
1.The abyssal zone of the ocean experiences photosynthesis.
2.The ocean floor contains vast quantities of polymetallic nodules rich in valuable metals.
3.The International Seabed Authority (ISA) is responsible for regulating deep-sea mining in international waters.
Which of the statement(s) given above is/are correct?
Answer: B
Notes:
Explanation –
Statement 1 is incorrect. The abyssal zone is a deep part of the ocean that does not receive sunlight, making photosynthesis impossible.
Statements 2 and 3 are correct. The ocean floor, particularly areas like the Clarion-Clipperton Zone, contains significant quantities of polymetallic nodules rich in metals such as manganese, nickel, copper, and cobalt. The ISA is the organization responsible for regulating deep-sea mining activities in international waters to ensure that such activities are conducted in an environmentally sustainable manner.
