NJIT Physics 203 Earth in Space Exam 2
UPDATED Actual Exam Questions and
CORRECT Answers
geology - CORRECT ANSWER✔✔- the study of the Earth's geosphere



geosphere - CORRECT ANSWER✔✔- the solid part of the earth



mineralogy - CORRECT ANSWER✔✔- the study of minerals



mineral - CORRECT ANSWER✔✔- Any naturally occurring solid, inorganic object with a
definite chemical structure


properties of a mineral - CORRECT ANSWER✔✔- color, streak, luster, light transmittance,
hardness, tenacity, cleavage, habit, density, specific gravity, taste, smell, magnetic properties,
chemical reactivity


color (mineral property) - CORRECT ANSWER✔✔- least reliable way to identify a mineral



streak (mineral property) - CORRECT ANSWER✔✔- the color of a mineral in its powder
form is more reliable


light transmittance (mineral property) - CORRECT ANSWER✔✔- transparent: see through
opaque: no light
translucent: kind of see through


hardness (mineral property) - CORRECT ANSWER✔✔- resistance to scratching/rubbing
without breaking


mohs scale - CORRECT ANSWER✔✔- measures hardness of a mineral from 1-10
1: talk (baby powder)

,10: diamond
you can scratch minerals together to see which is harder
pocket knife: 4.5
fingernail: 2.5


tenacity (mineral property) - CORRECT ANSWER✔✔- resistance to breaking/deforming
to measure it you need to break or at least deform the mineral
no scale to measure it


cleavage (mineral property) - CORRECT ANSWER✔✔- crystal geometry of a mineral when
you break it (classified by orientation of the cleavage planes)


habit (mineral property) - CORRECT ANSWER✔✔- the crystal geometry of a material if it
forms without confinement
(most of the time, it is not realized as most minerals form with at least some confinement)


density (mineral property) - CORRECT ANSWER✔✔- = mass/volume
every mineral has its own density


specific gravity (mineral property) - CORRECT ANSWER✔✔- the density of an object in
comparison to the density of the water
= density of substance/density of water


magnetic properties (mineral property) - CORRECT ANSWER✔✔- can be tested if it
attracts metal


silicates - CORRECT ANSWER✔✔- the most common type of mineral
based on SO4, tetrahedral structure


types of silicates in increasing complexity - CORRECT ANSWER✔✔- nesosilicates,
sorosilicates, single chain inosilicates, double chain inosilicates, phyllosilicates, tectosilicates

, types of silicates from darkest to lightest - CORRECT ANSWER✔✔- nesosilicates,
sorosilicates, single chain inosilicates, double chain inosilicates, phyllosilicates, tectosilicates


darker silicates are more dense due to the most amount of metals such as magnesium and iron
lighter silicates are less dense due to the smaller amount of metals


sulfates - CORRECT ANSWER✔✔- mineral group based on sulfur oxygen



carbonates - CORRECT ANSWER✔✔- mineral group based on carbon oxygen



oxides - CORRECT ANSWER✔✔- mineral group based on metals connected with oxygen
- iron (red), aluminum, copper (green)


halides - CORRECT ANSWER✔✔- a mineral group based on the halogens



native elements - CORRECT ANSWER✔✔- based on one atom type only
- pure iron/gold


petrology - CORRECT ANSWER✔✔- the study of rocks



rock - CORRECT ANSWER✔✔- any naturally occurring, inorganic solid that is a
mixture/aggregate of minerals with no definite chemical structure


petrography - CORRECT ANSWER✔✔- the study of the classification of rocks



petrogenesis - CORRECT ANSWER✔✔- the study of how rocks form



types of rocks - CORRECT ANSWER✔✔- igneous, sedimentary, metamorphic
