Igneous
Magma vs lava
Magma on erupts on surface=lava, magma=molten rock underground
5 processes of it forms
Weathering, erosion, deposition, compaction, cementation
How is it formed
Intense heat and pressure like tectonic plates
What are Rock made up of
A solid mixture of Minerals/grains
Igneous rock
Describe intrusive and extrusive
intrusive=on surface therefore less crystal growth formed by lava
extrusive=in crust therefore more crystal growth because its insulated formed by magma
3 types of classification are...
chemical, biochemical, and clastic
2 types of classification are...
Foliated and nonfoliated
Define Texture
The size of the grains and how they fit together
After igneous
it can get extreme heated and pressured into metamorphic or uplift and weather/erosion can turn it into sedimentary
does lava or magma make obsidian
Lava
4 natural causes of weathering/erosion
wind, ice, water, and gravity
Describe Foliated
twisted or bent layers
Define Composition
The minerals or grains present in a rock
after sedimentary
sedimentary then becomes exposed to extreme heat and pressure turning it into metamorphic rock
Does lava or magma make granite
magma
Texture of sedimentary can appear...
Random, ununiform
describe nonfoliated
random interlocking textures
Define Grains
Individual mineral crystals broken bits of minerals/pieces of rock
What happens after sedimentary turns into metamorphic
it ultimately melts into magma
why is it called "father of all rocks"
because it forms everywhere and all other rocks are created with ingenious rock at some point
Some examples of this rock are...
Limestone, Chert, Arkose, Shale, Sandstone, Conglomerate
some examples of this are...
Marble, slate, gneiss
What can composition tell about where/how a rock was formed
Was it formed inside the earth from magma, on the earth’s surface when the pieces were put together, or was it formed inside the earth because of extreme temperature and pressure?
After metamorphic melts then becomes...
crystalizes back into igneous and process repeats
