Which of the following is not a way in which minerals can form?

Question

A.) Elements that drop from the wind or water make layers that solidify into mineral.

B.) Minerals form when called magma cools and atoms bond together into mineral crystals.

C.) Minerals form when water that has atoms of dissolved elements in it evaporates away.

D.)None of the above.

Answer 1

Katy,

The answer is "A". Individual atoms of elements do not drop from wind and form minerals, only pre-existing particles do this to form rocks. Atoms and ions of elements can precipitate from water to form minerals, but the fact that they include wind in answer "A" makes it the correct answer to the question.

And by the way, what jerk is thumbs-downing answers without the necessary background to know whether they are right or wrong??? jim z and skeptik's answers are 100% correct, and yet they now look bad because someone is giving them thumbs-down. Was this you, Michael? Please don't give an answer thumbs down unless you are absolutely confident that it is wrong.

Answer 2

A would not typically form minerals without something to solidify it to a solid. Elements dropping from the wind or water would already be a mineral if it were to happen. Elements don't typically drop from the water.

Answer 3

The answer is D. Beware of the double negative; the choices A, B and C are all true ways in which minerals can be deposited. Therefore "NONE of the above" is NOT a way minerals can form.

Answer 4

A)

That describes the way in which sedimentary rock forms, but not how its composite minerals are created.
