Choose the physical properties that the geologists look in while identifying various minerals.

(A) Colour

(B) Hardness

(C) Cleavage

(D) All of the Above

 

Answer :

So, The correct answer is (D) : All of the above

Explanation :

  • To help with identification, geologists must look closely at the physical properties of a  mineral.
  •  These properties can include:  
    • color,  
    • Streak ( the color of a mineral in its powdered form),
    • hardness, 
    • Cleavage (Cleavage refers to the way some minerals break along certain lines of weakness in their structure) , 
    • specific gravity ( also known as "relative density", it is the ratio between the weight of a stone in the air and the weight of an equal volume in water),
    • crystal  form ( characteristic external shape of a mineral) 
    • and others.
