A naturally formed,
inorganic solid that
has a crystal structure
What is a mineral?
The six physical
properties of minerals
What are luster,
cleavage, fracture,
streak, density, and
hardness?
The structure of a
mineral
What is crystaline?
Scale that indicates a
mineral’s resistance to
scratching
What is Moh’s Scale?
One of the 92 smallest
parts of a mineral that
cannot be broken
down into a purer
substance
What is an element?
The ability of a
mineral to resist
scratching
What is hardness?
The way a mineral reflects light
What is luster?
The splitting of a
mineral along smooth
flat surfaces
What is cleavage?
The color of the
powder of a mineral
What is streak?
The manner in which a
mineral breaks along
either a curved or
irregular surface
What is fracture?
The ratio of the mass
of a substance to the
volume of the
substance
What is density?
The number on the
Moh’s scale for Talc
What is one?
The number on the
Moh’s scale for a
diamond
What is ten?
A mineral with a
hardness greater than
quartz (7) and less
than a diamond would
have this hardness
What is 8 or 9?
The hardness of a
mineral that could not
scratch or be scratched
by Talc
What is 1?
A mineral that glows
under ultra violet light
is said to have this
property.
What is fluorescence?
A mineral that fizzes
or bubbles when a
weak acid is placed on
the mineral.
What is chemical
reaction?
A mineral that causes
an image to double
What are optical
properties?
A mineral that attracts
iron
What is magnetism?
A mineral that
contains radium or
uranium
What is radioactivity?
The last seismic waves
to arrive and are most
destructive
What are surface
waves?
The fastest seismic
waves. Arrive first and
can move through
solids, liquids and
gases
What are P waves?
Seismic waves are the
second to arrive and
cannot move through
liquids
What are S waves?
The place on the Earth
that does not receive
seismic waves
What is the
Shadow zone?
The place between the
crust and the mantle
that causes seismic
waves to increase in
speed.
What is the Moho
Zone?
