Consider the following statements:

Characteristic feature of minerals are

[A] Minerals have a definite chemical composition

[B] Minerals are inorganic in nature

[C] The atoms that make up minerals are not arranged in an orderly pattern

[D] Minerals are the "Building Blocks of rocks"

Choose the correct answer from the options given below:

Correct option is B

✅ Correct option: (b) — [A], [B] and [D] only
Explanation of correct statements:
· (a) Minerals have a definite chemical composition
· True.
· Each mineral has a specific chemical formula or a limited range of composition.
· (b) Minerals are inorganic in nature
· True.
· Minerals form through inorganic geological processes, not biological ones.
· (d) Minerals are the "building blocks of rocks"
· True.
· Rocks are aggregates of one or more minerals.
❌ Why statement (c) is incorrect
· (c) The atoms that make up minerals are not arranged in an orderly pattern
· False.
· Minerals are defined by having an orderly, repeating internal atomic structure (crystalline structure).
· Lack of orderly arrangement is a feature of amorphous substances, not minerals.
❌ Why other options are incorrect
Option (a): (a), (b) and (c) only
· Includes statement (c), which is incorrect.
Option (c): (a), (b), (c) and (d)
· Includes incorrect statement (c).
Option (d): (b), (c) and (d) only
· Omits correct statement (a) and includes incorrect (c).
�� Key Points to Remember
· Minerals have definite chemical composition.
· Minerals possess an orderly crystalline structure.
· Minerals are inorganic and are the basic units of rocks.
· Crystallinity distinguishes minerals from amorphous solids.
