What causes deep water currents?

Lesson 2.12



Question 2 options:

none of the choices


Differences in water density drive deep water currents.


Difference in sharks and fish


Difference in seaweed and coral

Answer 1

Explanation: These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. Sharks are fish. ... A shark's skeleton is made of cartilage, a type of strong but flexible tissue. Most other fish are covered in smooth, flat scales. A shark is covered in sharp, toothlike scales called denticles.

Answer 2

Differences in water density drive deep water currents.

Step-by-step explanation:

Deep ocean currents (also known as Thermohaline Circulation) are caused by: The sinking and transport of large masses of cool water gives rise to the thermohaline circulation, which is driven by density gradients due to variations in temperature and salinity.
