1
a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure.
mineral
2
What are the 10 examples of rock minerals? (The big 10)
olivine, augite, hornblende, biotite, calcium-rich plagioclase (anorthite), sodium-rich plagioclase (albite), potassium-rich feldspar (commonly orthoclase), muscovite, quartz, calcite
3
What are the 5 minerals in rocks
silicates, carbonates, sulfates, halides, oxides
4
3 main types of rocks
sedimentary, igneous, metamorphic
5
Igneous
granite, scoria, pumice, obsidian
6
Sedimentary
sandstone, limestone, shale, conglomerate, gypsum
7
Metamorphic
marble, slate, quartzite, gneiss
8
7 major minerals
calcium, chloride, magnesium, phosphorus, potassium, sodium, sulfur
9
When rocks are pushed deep under the earth’s surface, they may melt into magma. If the conditions no longer exist for the magma to stay in its liquid state, it will solidify into an _____
igneous
10
The rock exposed to high temperatures and pressures can be changed physically or chemically to form a different rock, called .
metamorphic
11
Rocks exposed to the atmosphere are very unstable and subject to the processes of weathering and erosion. This process breaks the original rock down into smaller fragments and carries away dissolved materials. _____rocks form from deposits that accumulate on the Earth’s surface.
sedimentary
12
any piece of naturally existing solid mass or aggregate of one or more minerals.
rock
13
is a fundamental concept that shows the transitions among the three basic rock types (metamorphic, igneous and sedimentary). In simple terms, it is a chain of processes that produce and transform the rock types in Earth’s crust.
rock cycle
14
4 main types of igneous rocks
felsic, intermediate, mafic, ultramafic
15
Types of igneous rocks texture
aphanitic, phaneritic, pegmatitic
16
Two broad types of igneous rocks
intrusive (plutonic) rocks, extrusive (volcanic) rocks
17
got their name from Latin ignis, meaning “fire”. This makes sense because rthese rocks are formed by volcanic activity. The temperature is very high that materials melt. MAGMA is molten rocks generated by partial melting of rocks in Earth’s mantle. Magma consists mainly of silicon(silica SiO2) oxygen and lesses amounts of Aluminun (Al), calcium (Ca) sodium (Na) potassium(K), magnesium(Mg) iron(Fe)
igneous rocks
18
are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. ________ often have distinctive layering or bedding. _______ rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface. If sediment is buried deeply, it becomes compacted and cemented, forming _______ rock.
sedimentary rocks
19
3 kinds of sedimentary rocks
clastic, organic (biological), chemical
20
started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. _______ rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
metamorphic rocks
21
are generally made up of two of more minerals, mixed up through geological processes.
rocks
