The answer is a. partial freezing.
These deep-ocean<span> currents are driven by differences in the </span>water's<span> density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline </span>circulation<span>. In the Earth's polar regions </span>ocean water<span> gets very cold, forming </span>sea<span> ice.</span>
