Raffy reviewer Flashcards
What are the composition of minerals?
-Naturally-occuongInorganic, Solid, Repnite chemical composition, Ordered in temal structure
Mineral describes the appearance of light as it is reflected off its surface.
LUSTER
Specific gravity is a measure of the density of a mineral
DENSITY
The manner in which a mineral breaks is dependent on its molecular bonding. and structure.
CLEAVAGE & FRACTURE
Is a measurement of the strength of the chemical bands 177 its structure
HARDNESS
It forms a definite structure which eyselaes into a specific crystal form.
-CRYSTAL FORM & HABIT
Reliable feature for identifying minerals because it can be altered by chemical- impunties within its structure.
-COLOR & STREAK.
Defined as a naturally-occuring, morganic, solid with composition and an andered internal structure. a depnite chemical
MINERALS
Most of the common rock-forming minerals are
SILICATES
Consist of metal cations bonded oxygen anions.
OXIDES
Consist of metal cation bonded to sulfide.
SULFIDES
Consist of metal cation banded to the So anionic group.
SULFATES
Are composed of a halogen on, such as chlorine which promo halle.
HALIDES
Are chovaterized by the presence of carbonic in
CARBONATES
Consists of a single motal such as copper and gold
NATIVE METALS
It is trasportation of fragments
EROSION
It is the laying down of sediments carried by wind, water, or ice.
DEPOSITION
He was the first person to recognize the widespread accurance & igneous roks and to understand their origin
JAMES HUTTON
Rachs form when pre-existing racks are exposed to high heat and
pressure deep within the Earth.
METAMORPHIC ROCKS
Where are rocks found?
LITHOSPHERE
When the dominant alterning factor is pressure (tectonic activity)..
REGIONAL METAMORPHISM
When the dominant altering factor is heat (old roch material and magmal.
CONTACT METAMORPHISM
Formed from magma that cools slowly beneath the Earth’s surface.
- INTRUSIVE ROCK’S
Formed from lava that cools quiclsly on the Earth’s surface
EXTRUSIVE ROCKS
