Igneous Rocks
Extrusive igneous rocks can be found at which types of plate boundaries?
extrusive igneous at divergent (seafloor spreading), and both intrusive and extrusive at convergent (subduction... volcanic eruption)
These are rocks that can become metamorphic rocks.
sedimentary, igneous, and most metamorphic rocks
The three categories all rocks can be put into.
igneous, sedimentary, and metamorphic
molten means...
melted... ex, magma and lava are molten rock
True/False: Rock that is heated becomes igneous rock.
False... igneous ONLY if it melts all the way. (Metamorphic if just heated.)
The movement of sediment.
erosion
These two things are required for a metamorphic rock to form.
heat and pressure
when a rock was sediment that hardened, then went under tremendous pressure, then was melted down and crystalized or cooled inside a volcano ENDS as this type of rock.
intrusive igneous rock
What are the tiny pieces of rock that are formed as a result of weathering?
sediments
The process of compaction and cementation is also known is this.
lithification
Sandstone (sedimentary) must go through his to become Quartzite (metamorphic).
heat and pressure
These types of rocks can become sediment by weathering.
any type of rock!!!
Metamorphic rocks get their name also from the latin word morph, meaning this.
"form" or "to change"
Igneous rocks can be classified into these two types.
intrusive (under surface, ex. basalt) and extrusive (above surface, ex. granite)
Breaking down of rock is called....
weathering
Where do metamorphic rocks form?
deep in crust, near plate boundaries or volcanoes
Correct order of 5 steps to form sedimentary rock?
weathering, erosion, deposition, compaction, and cementation
When sediments are dropped or left somewhere...
deposition
This type of igneous rock are made when magma comes out of the Earth.
What is extrusive igneous rock (ex. basalt)?
The two types of weathering?
physical and chemical
Metamorphic rocks with stripes (or bands) of crystals are...
foliated metamorphic rock
This is how rocks on the surface get pushed into the Earth's mantle.
subduction
the breaking down of rock by acidic water, oxygen, or other chemicals is...
chemical weathering
