|
Igneous rock is formed from
|
Crystallization of molten magma
|
|
In a sedimentary rock, small rounded particles indicate
|
Long distance and long travel time
|
|
The most common outpouring of lava occurs as
|
Fissure eruptions
|
|
As the process of crystallization continues (from molten liquid to solid crystal) the composition of the molten liquid becomes
|
Both depleted in the minerals that have already crystallized and enriched in the minerals that have yet to crystallize
|
|
The majority of surface rocks are
|
Sedimentary
|
|
Rocks with a high water content have a
|
Lower melting point
|
|
The layered appearance of foliated metamorphic rocks is due to the
|
Realignment of sheet-structured minerals so that they are perpendicular to compressive forces.
|
|
As rock is heated, the first minerals to melt are those
|
With the lowest melting point
|
|
Plutons form from magma
|
Below the earth's surface
|
|
A foliated metamorphic rock derived from granite is
|
Gneiss
|
|
For the crystallization of minerals from a magma melting point determines which mineral will form first. For evaporite minerals
|
Solubility determines which mineral will form first
|
|
Rocks can begin to melt if
|
All of these
|
|
Most minerals can be identified by easily observable physical properties. In order of most useful to least useful, the identifiable physical properties are
|
Hardness, cleavage, density, crystal form, and color
|
|
Mica is not found in
|
Quartzite
|
|
Minerals that have strong bonds between flat crystal surfaces tend to
|
Show poor cleavage
|
