Final answer:
Cooling, evaporation, and ice formation increase ocean water density by affecting temperature and salinity.
Explanation:
Factors that cause ocean water to become denser:
- Cooling: Lower temperatures decrease molecular movement, making water denser.
- Evaporation: Freshwater removal increases salinity, making water denser.
- Ice Formation: Ice formation excludes salt, increasing seawater density.
These processes mainly affect surface water, leading to density-driven movements that create deep ocean currents.
