The central oceanic area of debris concentration is known as the zone of a) accumulation b) convergence c) circulation d) spiral migration e) depletion

Option (B)

Explanation:

The Great Pacific garbage trash is usually defined as the large accumulation of the marine debris particles present in the northern central part of the Pacific ocean. This garbage patch has two distinct ends, which is commonly considered as the eastern and the western patch. The eastern patch covers the region from Hawaii up to California, and on the other end, the western patch covers the region from Japan to the Hawaiian islands.

The subtropical convergence zone is referred to as the long oceanic water current that links both the western and the eastern patch and this covers the central portion of the Pacific ocean where these debris particles are accumulated.

So, this area is also known as the zone of convergence.

Thus, the correct answer is option (B).
