Question

question 18
sources of deep water in the ocean include all of the following except:
northern subpolar latitudes.
subtropical convergences.
arctic convergence.
southern subpolar latitudes.
antarctic convergence.

Explanation:

Deep - water formation in the ocean occurs in polar and sub - polar regions. The Arctic convergence, northern subpolar latitudes, southern subpolar latitudes, and Antarctic convergence are all associated with processes that can lead to deep - water formation. Subtropical convergences, on the other hand, are not a source of deep water. Subtropical regions are generally characterized by warm surface waters, and the processes at subtropical convergences do not result in the sinking of water masses to form deep water.

Answer:

subtropical convergences.
