Question
Which of the following is not a characteristic of a mineral.
Question 1 options:
it can be naturally occuring or man-made
it contains a specific chemcial composition
Most minerals are inorganic
it contains a definite crystalline structure
Question 2 options:
it can be naturally occuring or man-made
it contains a specific chemcial composition
Most minerals are inorganic
it contains a definite crystalline structure
Question 2 options:
If a mineral breaks to form distinctive planar surfaces that have a specific orientation in relation to the crystal structure, then we say that the mineral has __________. Cubic, Prismatic (2 at 90 degrees & 2 not at 90 degrees) and rhombohedral are all terms to describe this. ______________
Explanation / Answer
1. Mineral is defined as a natural occuring, inorgenic composition having a definite chemical composition and structure. Thus option A is partially wrong.
2. It may be hexagonal or monoclinic, if both (equal to 90o and not eqauls to 90o exist in crystal structure)
