Definitions
Molten rock inside the earth
Magma
Forms when hot molten rock crystallizes and solidflies
Igneous rock
Formed from Pre-existing rocks or pieces are once-living organisms
Sedimentary rock
Some other type of rock, but have been substantilly changed from their original igneous, sedimentary or earlier metamorphic rock
Matamorphic rock
What is equivalent to basalt?
Gabbro
Material deposited by wind, water or glaciers
Sediment
How do other types of rocks change into igneous rocks
Cooling and crystallization
How do other rock types change into Sedimentary rocks?
Rock exposed by mountain building or even modest uplift weathers and erodes and the resulting sediments can be sedimentary rocks
How do other rock types change into Metamorphic rocks?
High heat and pressure
How do rocks change from one type to another?
Crsytallization, Erosion and sedimentation and metamorphism
The breaking down or dissolving of rocks and minerals on earths surface
Weathering
What is the aphanitic equivalent of granite?
Rhyolite
How do crystalline sedimentary rocks form?
Chemical reactions
How are minerals formed in metamorphic rocks?
by rearrangement of mineral components or by reactions with fluids that enter the rocks
How many stages are in the rock cycle?
5 stages
The process in which the surface or the earth is worn away by the actions of water, glaciers winds, waves etc
Erosion
What are the two types of igneous rocks
Intrusive and extrusive
Why must water evaporate for sedimentary rock to form?
the evaporation process removes the water from the mineral solution, allowing the minerals to form rock.
How do the metamorphic rocks schist and quartzite differ?
Quartzite contains the mineral quartz and schist does not
What starts the rock cycle?
A hot molten liquid rock called magma or lava
When sediments are deeply buried, placing them under pressure because of the weight of overlying layers
Compaction
What is earths crust mostly made out of
Igneous rock
Do sedimentary rocks break easily?
Yes
How does increased metamorphism affect schist?
The size of the mineral grains tends to enlarge
How does the rock cycle end?
No beginning and no end
