Question 12 • WCA 4130 Earth and Space Science 1st Quarter 26-27

A mineral forms in water heated by magma inside Earth.Which statement best describes this mineral?

Answer
A
The mineral formed through evaporation.
B
The mineral crystallized from molten material.
C
The mineral formed when a hot water solution cooled.
D
The mineral likely has all the same properties as the surrounding rock.

Explanation

Water heated by magma can dissolve minerals and carry them through cracks in rock. As the hot water solution cools, dissolved minerals crystallize and form a mineral deposit. This matches “the mineral formed when a hot water solution cooled”; crystallizing directly from molten material would describe formation from magma or lava.
