Ocean water density varies more at the the poles throughout the year than at the equator. Lesson 2.08

True
False

Your answer would be true.

Explanation:

I know what quiz you are taking.

Q2: Ocean water is more dense because of the salt in it. Increasing salinity also increases the density of seawater. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water.

Q3: The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles. The speed and direction of air and sea currents are determined primarily by air temperature gradients. (True)

Q4: This water sinks and moves toward the equator where it replaces less dense, warm water.

Q5: The Coriolis effect

Q6: The rotation of the earth causes the Coriolis effect, which results in wind and ocean currents having a curved shape

Q7: As it rises, it cools and begins to flow toward the poles. As this air leaves the equator, cooler and heavier air from the poles flows along the surface to take its place.

Q8: True

Q9: It causes them to flow from north to south

Q10: True
