Question

Which of the following statements is true?

A) The ocean contains very little NaCl.
B) Dissolved minerals from rocks are deposited in the ocean.
C) Density is a comparison between volume and salinity.
D) One atmosphere is equal to 20 pounds per square inch (psi).

Answer 1

Answer: Option (B) is the correct answer.

Step-by-step explanation:

It is known that salt water contains high amount of sodium chloride (NaCl).

Also, when it rains then minerals from the rocks are washed or carried away by rain water. Therefore, this rain water passes through various routes and finally reaches to the ocean.

Therefore, the minerals from rocks are deposited in the ocean.

On the other hand, density is defined as mass divided by volume.

Mathematically, Density =
`(mass)/(volume)`

Also, it is known that 1 atmosphere equals 14.69 pound per square inche and not equals to 20 pounds per square inch.

Thus, we can conclude that the true statement is dissolved minerals from rocks are deposited in the ocean.

Answer 2

The statement that is true is B. Dissolved minerals from rocks are deposited in the ocean. All of the other statements are not correct, they are false.
