They move warm water along the bottom of the ocean from the Atlantic ocean to the Pacific Ocean

They move cold water along the bottom of the ocean from the Pacific Ocean to the Atlantic Ocean

Answer 1

The correct statement about deep currents is:

They move cold water along the bottom of the ocean from the Pacific Ocean to the Atlantic Ocean.

Deep ocean currents, also known as thermohaline circulation, are driven by differences in water density, which is affected by temperature (thermo) and salinity (haline). Cold water, which is denser, tends to sink and flow along the ocean floor, contributing to the global conveyor belt of ocean circulation.
