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.
