Metamorphic
The definition of the word metamorphic
Change/transform
What two materials form igneous rock
Magma and Lava
Sedimentary rocks are broken down through what process?
Erosion
What two forces typically break down rocks
Wind and water
Which part of the scientific method involves making an educated guess?
Hypothesis.
These two factors are required for metamorphic rocks to be formed.
extreme heat and pressure
Extrusive igneous rock cool quicker than intrusive igneous, why?
Because they are exposed to the oxygen in the surface.
What two examples of sediments?
Sand, gravel, dirt
What is the least reliable way to identify minerals?
Color
This process of rock breakdown and movement from one place to another
Erosion
What kind of rock will metamorphic change into when exposed to magma
Igneous
What kind of igneous rock are formed from magma and what kind are formed from lava
Magma: Intrusive igneous
Lava: Extrusive Igneous
Sedimentary rocks are usually arranged in what?
Layers
The difference between a geologist and a petrologist is what?
Geologist studies the earth
Petrologist studies rocks
The process of sedimentary rocks being arranged in layers
Stratification
How many kinds of metamorphic rocks are there?
Two. Foliated and Non-foliated
Intrusive are different from extrusive igneous rocks because of what?
They cool slower and they have larger crystals
Sedimentary rocks are known for being the only kind of rock to have these
Fossils
The process of rocks changing over time from one kind of rock to the other is know as
The rock cycle
Since we know the mineral Muscovite is a thin mineral that shatters very easily, would its rate on the hardness scale be very high or low
Very low because low rated minerals on the moh's hardness scale are softer and easier to scratch
Where are metamorphic rocks typically formed?
Deep within the earth
Intrusive igneous and extrusive igneous have crystal sizes that are different based on what factor?
cooling speed
Sedimentary rocks are typically found where?
At the bottom of oceans or lakes
What mineral is pencil lead made of?
graphite
The formula for solving Mass is what?
Density times volume (m=D*V)
