Physical And Chemical Properties Of Minerals

Test Description: Differences in physical and chemical properties and their resultant characteristics.

Instructions: Answer all questions to get your test result.

1) Minerals are identified on the basis of

Athe size of their crystals Bthe method by which they were formed Cthe type of rock in which they are found Dtheir physical and chemical properties

2) The mineral mica breaks evenly along flat sheets mainly because of its

Adensity Bhardness Cchemical composition Datomic arrangement

3) Scratching a mineral against a glass plate is a method used for determining the mineral's

Ahardness Bcleavage Ccolor Dluster

4) The relative hardness of a mineral can best be tested by

Adetermining the density of the mineral Bsqueezing the mineral with calibrated pliers Cscratching the mineral across a glass plate Dbreaking the mineral with a hammer

5) One of the most abundant minerals in beach sand is quartz. Which property of quartz could account for its abundance?

Aluster Btexture Chardness Dcolor

6) Which mineral property is illustrated by the peeling of muscovite mica into thin, flat sheets?

Astreak Bcleavage Chardness Dluster

7) The physical properties of minerals result from their

Ainternal arrangement of atoms Btype of cleavage and hardness Ctexture and color of streak Ddensity and color

8) Different arrangements of tetrahedra in the silicate group of minerals result in differences in the minerals'

Ahardness, cleavage, and crystal shape Bcleavage, color, and abundance Cage, density, and smoothness Dchemical composition, size, and orig

9) Moh's scale would be most useful for

Afinding the mass of a mineral sample Bfinding the density of a mineral sample Ccounting the number of cleavage surfaces of a mineral sample Didentifying a mineral sample
