Answer:
The movement of the water pushes the denser water down, while the upwelling current pushes the less dense water down.
Explanation:
Uowelling currents cause the ocean waters to munch vertically. this movement is done in relation to the temperature and density of the water. This is because this type of current causes cold, nutrient-rich and denser water to be pushed to the surface, while hot, less dense water is pushed down.
