NJIT PHYSICS 203 EARTH IN SPACE EXAM 2 COMPLETE QUESTIONS AND 100%
VERIFIED ANSWERS LATEST UPDATED
The study of the Earth's geosphere is known as geology.
The solid portion of the earth is called the geosphere.
The study of minerals is known as mineralogy.
A mineral is any solid, inorganic substance that occurs naturally and has a
certain chemical structure.
Colour, streak, lustre, light transmittance, hardness, tenacity, cleavage, habit,
density, specific gravity, taste, smell, magnetic properties, and chemical
reactivity are some of the characteristics of a mineral.
The least accurate method of identifying a mineral is by its colour (a mineral
characteristic).
streak (mineral property) - ANSWER A mineral's colour is more consistent
when it's in powder form.
The mineral property of light transmittance is transparent, or see-through.
opaque: devoid of light
Transparent: rather transparent
Hardness (a mineral property): ANSWER's ability to withstand rubbing and
scraping without breaking
Mohs scale: ANSWER rates a mineral's hardness on a scale of 1 to 10.
Talk (baby powder), first
10. Diamond
To determine which mineral is harder, you can scratch them together.
knife in the pocket: 4.5
2.5 fingernails
Tenacity, a mineral quality, is the ability of an answer to resist breaking or
deforming.
, The mineral must be broken or at least deformed in order to be measured.
no measurement scale
ANSWER crystal geometry of a mineral upon breaking (categorised by
orientation of the cleavage planes) is known as cleavage (mineral property).
habit (mineral property): If a material develops without confinement, ANSWER
the crystal geometry of that substance.
Since most minerals form with at least some restriction, it is typically not
realised.
mineral property density - ANSWER = mass/volume
Each mineral has a unique density.
Specific gravity is a mineral characteristic that measures an object's density
relative to that of water.
= density of water divided by density of material
If it attracts metal, the answer can be checked for magnetic characteristics (a
mineral property).
Silicates are the most prevalent kind of mineral.
Tetrahedral structure based on SO4
ANSWER nesosilicates, sorosilicates, single chain inosilicates, double chain
inosilicates, phyllosilicates, and tectosilicates are silicate forms in increasing
complexity.
ANSWER nesosilicates, sorosilicates, single chain inosilicates, double chain
inosilicates, phyllosilicates, and tectosilicates are the different types of silicates,
arranged from darkest to lightest.
Because darker silicates contain more metals, such iron and magnesium, they
are denser.
Because there are fewer metals in lighter silicates, they are less dense.
Sulphates are a sulfur-oxygen-based ANSWER mineral group.
The ANSWER mineral category based on carbon and oxygen is called
carbonates.
Oxides are a type of mineral group that is based on metals that have an oxygen
bond.
