science test Flashcards
the lithification of sand forms what type of rock?
sandstone
stone is made from what type of rock sediment?
silt
the lithification of gravel forms what TYPE of rock?
conglomerate
solidification of clay forms what type of rock?
shale
Refers to having bands of light and dark minerals
foliated
Slate is classified as what type of metamorphic rock (high, intermediate,` or low)
low grade
the process by which sediments are turned into sedimentary rock
lithification
Is limestone classified as clastic, chemical, or biochemical?
biochemical
The percentage of open space between sediment particles
porosity
type of metamorphism that occurs in large areas near the mantle
Regional Metamorphism
When a rock does not change chemically but is separated from its parent material
physical weathering
Gneiss is classified as what type of metamorphic rock (high, intermediate,` or low)
high grade
mineral or rock fragments that have come off of larger rocks
sediments
type of metamorphic rock that has large crystals surrounded by smaller crystals
porphyroblast
process of sentiments being placed in a new location
deposition
type of metamorphism that occurs when igneous intrusions move up into new rock layers
contact metamorphosis
process that occurs when minerals are dissolved or chemically changed
chemical weathering
type of metamorphism that occurs when very hot water reacts with rock
hydrothermal metamorphism
What are the main sources of erosion?
wind, glaciers, gravity
Where are crossbedded sediment layers deposited?
the desert
The changing of rocks from one form to another several times
rock cycle
Identify the rock whose parent rock is granite.
Gneiss
Identify the rock whose parent rock is (usually) shale
schist
Garnet’s form from the organization of minerals during metamorphism. What are they?
porphyroblasts
What three things does foliation in rock require?
needle like minerals, flat minerals, lots of pressure
What are 2 similarities between hydrothermal and contact metamorphism?
Lots of heat, parent rocks
original rock type that undergoes metamorphism
parent rock
What type of rock do minerals dissolved in water form
chemical
What do limestone and coal have in common
They both formed from living things, and they’re both sedimentary rocks
Identify this rock made of accumulated shells or coral.
limestone
process in which clastic sediments are produced
weathering
