Minerals – Geology Quiz 101

Minerals – Geology Quiz 101. Questions based on minerals are generally asked in SSC JE civil exams in combination with rocks. But generally, we don’t get much of time from other vast subjects of civil engineering to revise geology in depth. To ease that issue here are some quick flip card quiz based on minerals- geology. Terms used in the quiz are explained below the quiz/tests. Practice more quiz in our Short Quiz Section.

Some terms- (Physical properties of mineral)

Colour- Colour of mineral, on visible examination.
Iridescence- Rainbow of colour.

Lustre- Shine of mineral, light a mineral particle reflect.
Streak- If we grind a mineral into a fine powder, the colour of this powder is called streak.
Hardness- Resistance to abrasion and scratch. Measured by Mohs’ Scale of Hardness for minerals.

Mohs’ Scale of Hardness for minerals- Is a scale from 1- 10, 1 being soft mineral (talc) and 10 indicating “hard mineral”(Diamond).

Cleavage- Breaking of mineral(crystalline) in a certain direction.
