GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Alternatively, an intermediate layer is created if the density difference with the surrounding waters reaches zero before the density current arrives at the bottom of the ocean. In this scenario, the current spreads horizontally at an intermediate depth.

Detailed explanation-3: -Dense water (dyed) flows rightward through a hole in a partition near the base: light (clear) fluid returns leftward through a hole toward the top.

Detailed explanation-4: -However, changing the density of the surface water causes it to sink or rise, and these vertical, density-driven movements create the deep ocean currents.

Detailed explanation-5: -DENSITY CURRENTS move water vertically toward the ocean’s surface. AN UPWELLING moves water vertically from the surface to deeper parts of the ocean. Density currents are caused by density changes, which are brought on by changes in temperature or WIND.
