22
Q

Any solid mass of mineral or mineral like matter occuring naturally as part of our planet

23
Q

Processes within the rock cycle

A
Compaction and cementation 
Cooling and crystallization of magma
Melting
Weathering
Erosion
24
Q

2 types of igneous rocks

A

Extrusive or volcanic

Intrusive or plutonic

25
What drives the rock cycle
Earth's internal heat | Weathering
26
Formed as magma cools and crystalizes
Igneous rocks
27
Is formed by the alteration pre existing rock deep within earth by heat, pressure and or chemically active fluids
Metamorphic rock
28
It is mainly a result of the cooling history of the igneous rocks
Texture
29
Igneous rocks are classified based on...
Texture | Mineral composition
30
Magma crystalizes over a temperature range of at least 200c
Bowen's reaction series
31
Crystalizes deep below the surface
Intrusive
32
Is formed from the weathered products of pre existing rocks that have been transported, deposited, compacted and cemented
Sedimentary rocks
33
Produced when lava cooled quickly on or near earth's surface
Fine grained texture
34
The formation of one or more secondary magma from one parent magma
Magmatic differentiation
35
Rocks with composition between granitic and basaltic contains a mixture of both light and dark colored minerals
Andesitic rocks
36
Produced by slow then rapid cooling
Porphyritic rock
37
Rich in iron and magnesium but relatively low in silica
Dark silicates
38
A consequence of the chemical makeup of the parent magma and the environment of crystallization
Chemical composition
39
Originate from solid particles derived from weathering and are transported
Detrital sediments
40
Rocks that contain substantial dark silicate minerals and calcium rich plagioclase feldspar
Basaltic or mafic
41
Produced by rapid cooling
Glassy textures
42
It contains mostly of dark colored minerals
Ultramafic rocks
43
It contains a variety of mineral and rock fragments
Detrital sedimentary rocks
44
Produced when magma cools slowly at depth
Course grained texture
45
Contains greater amounts of potassium, sodium and calcium and are richer in silica
Light silicates
46
Give 3 dark and light silicates
Olivine Pyroxene Amphibole Quartz Muscovite mica Felspar
47
Composed of entirely light colored silicates
Granitic or felsic
48
It contains the product of biological processes or mineral crystals that form as water evaporates and minerals precipitate
Chemical sedimentary rocks
49
Metamorphism occurs in two settings
Thermal or contact metamorphism | Regional metamorphism
50
Metamorphic textures
Foliated and non foliated
51
What drives metamorphism
Heat Pressure and differential stress Chemically active fluids
