Which condition causes ocean salinity to increase?

A.
river water flowing out into the ocean

B.
high levels of precipitation

C.
high levels of evaporation

D.
thawing of polar ice caps

Answer 8

There are processes that increase salinity of the oceans and factors that decrease salinity.

Evaporation causes the salinity of the ocean to increase. This is the primary process taking fresh water out of the oceans. Fresh water enters the ocean through rain and rivers. Rivers bring in a small amount of new salt and dissolved minerals that remains after evaporation.

Freezing also affects salinity. Near the poles, particularly the antarctic, when ocean ice freezes it eliminate a significant amount of salt from the ice, leaving a saltier and denser brine behind. This denser antarctic brine sinks and initiates a current the flow from the antarctic water northward towards the deeper ocean. This is an important influence on circulation in the southern oceans.

The increase salinity of the oceans is also counteracted by processes in the oceans sediments that remove salt so on the average there has been little change in ocean salinity over the last few billion years.

Note: Ocean salt, as described here, is not merely sodium chloride, but also has a fraction of other dissolved ions. See related questions.

Answer 9

Sorry, if that's long. But I can't give DA's (direct answers) because it violates the CoC of OpenStudy.

Which explains how the moon and, to some degree, the sun cause tides on the earth?

Answer 22

A.
The moon and sun exert a gravitational pull on the earth. The moon pulls strongest on the ocean water on the opposite side, lesser on the solid earth, and the least on ocean water on the same side of the earth. The pull creates tidal bulges that are earth’s high tides. Low tides occur at the halfway point between the bulges.

Answer 23

B.
The moon and sun exert a gravitational pull on the earth. The sun pulls strongest on the ocean water on the same side, while the moon pulls on the ocean water on the side opposite the moon. The pull creates tidal bulges that are earth’s high tides. Low tides occur at the halfway point between the bulges.

Answer 24

C.
The moon and sun exert a gravitational pull on the earth. The moon pulls strongest on the ocean water on the same side, while the sun pulls on the ocean water on the side opposite the moon. The pull creates tidal bulges that are earth’s high tides. Low tides occur at the halfway point between the bulges.

i'm not i just think its a my brother was on my computer sorry

Answer 30

Which is the definition of the thermocline?

A.
The thermocline is the boundary between colder ocean water near the surface and warmer ocean water at greater depth.

B.
The thermocline is the boundary between warmer ocean water near the equator and colder ocean water near the poles.

C.
The thermocline is the boundary between warmer ocean water near the surface and colder ocean water at greater depth.

D.
The thermocline is where warm ocean currents sink to become cold ones.
