Rock Cycle Vocabulary Flashcards
-intrusive igenous rock that forms really deep inside the Earth
-Cools really slowly
-Coarse Grain crystals
Abbysal Rock
- intrusive igenous rocks that forms shallower
-cools a little faster
-medium grain crystals
Sub-volcanic rock
Particles that are moved and then dropped by water
alluvium
Intrusive igneous rock
that forms a large mass of rock
exposed by weathering
batholiths
sedimentary rocks composed of formerly living organisms
bicochemical sedimentary rocks
anythings that will from rocks from living creatures:
-shells
-marine snow
-fecal matter
-pieces of decaying matter
biological detritus
angular gravel (S)
breccia
a step in diagenesis where dissolved minerals act as glue
cementation
-layers build up
-weight builds up
-pressure increases which increases chances of diagenesis
compression
water gets squeezed out
overburden
hardens into real rock
lithification
rock fragments that are cemented together with silicate minerals
clastic sedimentary rocks
rounded gravel (S)
conglomerate
magma injected into surrounding rock, greatest changed where the magma touches the rock, greatest Temp. change
contact metamorphosis
any solid material in which the component atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry.
crystals
the chemical, physical, and biological processes that turns sediment into sedimentary rocks.
diagenesis
moving sediments
erosion
igneous rock formed above ground
extrusive igneous rock
erosion / movement with water
fluvial transport
stripes formed when rock is stretched and shortened during the process of metamorphosis
foliation
pieces of the earth like rocks etc.
geological detritus
A mineral that forms only under specific pressure and temperature conditions, and that therefore provides information about the metamorphic history of the rock in which it is found. The minerals kyanite, andalusite, and sillimanite
index minerals
Igneous rock that is formed by magma underground
intrusive igneous rock
From volcanoes/ mantle material
reaches surface(air/water), gas is released, volcanic eruptions, subariel/submarine
lava
the last step of diagenesis where it hardens into rock
lithification
volcanic/mantle material underground. gas bubbles and rises throughout, less dense than rock
magma
pieces of fecal matter
marine snow
Rock that is transformed under immense heat and pressure. rocks changed physically and chemically
metamorphic rock
Single chemical/pure substance
Minerals
particles that are settled from a solution
precipitate
the previous/ starting rock of metamorphic rock. original rock before change
protolith
crystal size changes during metamorphosis
recrystalization
convergent boundaries, over large rock areas, pressure from rock layers above
regional metamorphosis
combo of at least 2 minerals, mixture
rock
rock formed by minerals/particles or pre-existing organisms
sedimentary rock
pieces of rock/ minerals/ geological detritus
sediments
layers in sed. rocks
strata
intrusive ig. rock that forms shallower and cools a little faster, medium grain crystals
sub-volcanic
extrusive igneous rock that is relatively smooth and formed from lava. slow cooling , volcanoes
volcanic glass
