Describe how differences in water temperature and salinity affect deep water currents.

When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. THIS IS NOT FROM MY OWN WORDS, IF YOURE TYPING THIS DOWN PLEASE REPHRASE IT A BIT!! :)

Not the answer but here is the graph.
