Because of thermohaline circulation and other currents, question 1 options: the oceans of the world exist as distinctly different bodies of water the oceans of the world slowly mix, and are really one ocean. the temperatures of the oceans would become equal.

The oceans of the world slowly mix and are really one ocean because of thermohaline circulation and other currents.

Thermohaline circulation describes deep water currents which accounts for 90% of the ocean and their movement is due to gravity and density-driven forces. It is also influenced by the horizontal difference in salinity and temperature.

The movement of these water current is very slow; the water transports nutrients, heat, solids, and other material a great distance. It also drives warmer surface water. Thermohaline circulation occurs at deep ocean basins at the slow rate of 1 cm per second and it is influenced by convective currents which displace the water of different temperatures.
