Answer:
Density currents move vertically
Step-by-step explanation:
Density currents are those currents that result from density differences. These currents are started by those currents that flow along the bottom of oceans or lakes in nature. Most density currents are formed deep in the ocean. Differences in the density of water can also cause currents to form and move. Density is affected by temperature and salinity. But if we talk about direction of currents then the density currents move vertically.
