Question

How do temperature and salinity affect deepwater currents?

Question 13 options:
A)They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

B)As temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions.

C)They equalize the forces on undersea currents caused by the Coriolis effect as they replace more dense water with less dense water.

D)They create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean.

Answer 1

Answer:

its d They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Explanation:

Answer 2

Temperature and salinity affect deepwater currents by creating a density difference that causes dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. (Option A)

• The deepwater currents form due to density differences in the water.
• Temperature (thermo) and salinity (haline) are the factors behind this density difference.
• Hence, deepwater currents are called thermohaline circulation.
• In polar regions, very cold temperatures convert water into ice.
• As a result, the salinity of the surrounding water increases (as ice does not contain salt).
• This increases the density of the water as saline water is denser.
• This cold dense water sinks and warm less dense water takes its place where the same thing happens with this warm less dense water.
• This results in the thermohaline circulation or the deepwater currents
