Question

3 what causes currents deep below the ocean’s surface? a earth’s rotation creates movement deep below the ocean’s surface b strong winds cause currents to form deep below the surface c differences in ocean temperature and density create deep water currents

Explanation:

To determine the cause of deep - ocean currents, we analyze each option:

• Option A: Earth's rotation (Coriolis effect) mainly influences surface currents and large - scale atmospheric and oceanic circulation patterns at the surface or near - surface, not deep - ocean currents.
• Option B: Strong winds are the primary driver of surface ocean currents, as wind energy is transferred to the ocean's surface, and this energy does not penetrate deeply enough to create deep - ocean currents.
• Option C: Deep - ocean currents, also known as thermohaline currents, are caused by differences in water temperature (thermo -) and salinity (which affects density - haline). Colder, saltier (more dense) water sinks, and warmer, less dense water rises, creating a circulation pattern in the deep ocean.

Answer:

C. Differences in ocean temperature and density create deep water currents
