Which term is the line along which waters of different density converge, forming the boundaries between climate zones?

• A. Convergence Zone
• B. Caballing
• C. Countercurrent
• D. Current

Answer: (A)

Waters with different densities meet and come together at a boundary, forming a distinct front. This convergence line marks where the properties of water mass on one side (like temperature and salinity) shift to those on the other, helping delineate climate zones in the ocean. The term describes the boundary created by the coming together of two contrasting densities. Caballing is about two water masses mixing to form a new, denser mass, not about the boundary itself. A countercurrent is water flowing in the opposite direction to the main current, and a current is just any flow of water.
