Quiz 6 is based on Module 6

A rapid change in ocean salinity with change in depth is the

halocline

Which of the following statements regarding pH is not true?

As a whole, the pH of the ocean is slightly acidic.

Which of the follow is not correct about marine effect?

It is caused by high heat capacity of rocks.

Which of the followng is not true?

Salinity refers to all of the solid materials in seawater including dissolved and suspended substances.

Why does the the pH of the ocean changes only slighlty?

because of the carbonate buffer

The ion in sea water that is serves as a buffer to moderate the pH change in the ocean is:

carbonate

As the salinity of seawater increases, its:

density increases

As the temperature of seawater decrease, its

density increases

A rapid change in ocean density with change in depth is the

pycnocline.

The density of seawater in the high latitude (polar ocean) is influenced by the change in

salinity

The Principle of Constant Proportions states that:

the relative concentrations of the major ions in seawater does not change.

A rapid change in ocean temperature with change in depth is the:

thermocline.
