QUESTION: Which one of the following is not a characteristic of minerals?

A   They are created by natural processes.

B    They have a definite chemical composition

C    They are inexhaustible

D   Their distribution is uneven.

ANSWER:  They are inexhaustible

Characteristics           Description
Creation through natural process Minerals are formed through natural geological processes over long periods of time.
Definite chemical composition Each mineral has a specific chemical formula, defining its composition in terms of elements.
Crystal structure Minerals have an ordered atomic arrangement geometric pattern known as a crystal lattice.
Exhaustible resource Minerals are finite resources so these can be depleted over time through extraction and use.
Origin of minerals Minerals are formed from inorganic materials.
Uneven Distribution Minerals are not uniformly distributed around the world; their presence varies from location to location.
State of minerals Minerals are typically solid substances at room temperature and pressure.
Specific Physical Properties Minerals have unique physical properties like hardness, color, cleavage and luster.
Occurrence Minerals are found in nature and have not been artificially created by humans.
Economic importance Many minerals have commercial value due to their uses in industries like manufacturing, technology and construction.
Diversity There are thousands of different mineral species, each with its own set of properties and characteristics.
Occurrence of Minerals ·        Igneous Rocks

·        Sedimentary Rocks
