FORMATION OF METAMORPHIC ROCKS
A Metamorphic rock is one whose original form has been ________________ by
_____________ and ______________.
This alteration is called ________________________. These changes are NOT
caused by MELTING. If the rock melted and cooled it would be an IGNEOUS ROCK.
1.
Changes are caused by ______________________.
May include the creation and growth of __________________________.
2.
Rocks which are intensely __________________can also become
______________________ rock, making it more DENSE and
RESISTANT. The growth of new minerals may cause the rock to appear
___________________ or _______________ (stripes of light and dark
minerals). It can also _________________ (bend) or
__________________ original structure.
3.
There are two types of Metamorphism:
a. ____________________
b. ____________________
Regional Metamorphism: Occurs over
large areas with extreme pressures
and temperatures. The extreme heat
and pressure is what builds
_____________________.
Contact Metamorphic: Is the zone of
contact where an igneous intrusion meets
the existing rock but does not melt it.
Contact metamorphism occurs only at the
place where the magma
________________________ rock and
transfers heat via conduction.

Any kind of rock: IGNEOUS, SEDIMENTARY, and METAMORPHIC can undergo
__________________________ to form metamorphic rock.
____________________ Rock: Is rock from which metamorphic rock is formed.
LIMESTONE metamorphoses to become ____________________.
SANDSTONE metamorphoses to become ____________________.
SHALE metamorphoses to become _________________.
We will NOT find fossils in Metamorphic rock because __________________

FORMATION OF SEDIMENTARY ROCKS
Sedimentary rocks originate from: _______________________ because this is where
deposition occurs.
Sedimentary rock forms a thin ____________on top of existing rock.
1. Clastic:_________________________________________________________
2. Bioclastic: _________________________________________________________
3. Crystalline: _______________________________________________________
1. Clastic Sedimentary Rock: contain layers of _________________________
formed from the breakdown of other rocks. (
)
Characteristics of Clastic Sedimentary Rock ( ____________________ )
A. Varied particle size
B. Horizontal layers
C. Formed in water
Sedimentary rocks are UNLIKE loose sediments because sediments have been
___________________________ and __________________________ together.
Two examples of natural cement are: _________________ &

Classification of Sedimentary rocks is based on
______________________________or ____________________________.

_______________________________________________________
* Limestone is the accumulation of _______________ and __________________
* Coal is the remains of _____________ that accumulate in layers and become buried and
compressed for millions of years!!
3. Crystalline Sedimentary Rocks:
Chemical sedimentary rocks are formed from minerals that were _________________
in water. Minerals that were once dissolved are called
__________________________ and ___________________________
Crystalline sedimentary rocks are made of only one _____________________ and are
called ___________________________________
Examples include: ______________________ and ______________________
A fossil is evidence that a rock is ________________________________________.
Fossils are rare in ____________________ and ________________________ rocks.
