What is the most noticeable feature of sedimentary rock?
_____________________________________________
Composition and Classification:
1. Clastic – forms when _________________ or ________________
fragments are ____________________ together.
 Figure 2 page 41

Classified by ________________ of _________________________.
2. Chemical – forms when _____________________
___________________ out of a solution such as sea water.
 ____________________ dissolves rock material as it
passes through.
 Some dissolve material eventually crystallizes.
An example: ______________________________.

Metamorphic Rock (pgs 44 - 49)
Metamorphic means ___________________________.
What changes when metamorphic rock forms?
 _________________________

 _________________________
Origins:
 What conditions are needed for a rock to undergo
metamorphism? _______________________________________________
____________________________________________________________________
 It is the ________________________ and ______________________ at
which metamorphic rocks form that allows rock to heat to a
very high temperature.
 __________________ ______________________ within Earth’s
_____________ cause ______________________ _____________________
to be exerted on the rock.
1. Contact Metamorphic Rock
 Rock undergoes metamorphism by
______________________________________________________
 The greatest change takes place where
______________________________________________________
 Occurs near igneous rock formations.
2. Regional Metamorphic Rock
 Formed when _________________________ builds up
deep below other rock formations.
 Or when _________________ __________________ of
Earth’s crust ___________________.
_________________________ boundary.
Compostion:
 When __________________________ and _______________________
change, the original __________________ change into new
_______________________.

_____________ + _____________ + _____________ + Heat = __________
and
pressure
 Figure 4 (page 46)
Scientists can understand a metamorphics rocks history by
observing its mineral content.
Example: Metamorphic rock that contains ________________
formed at a __________________ depth and under greater
____________ and __________________ than a rock that contains
___________________.
Texture:
1. Foliated - __________________ grains are arranged in
________________.
 Figure 5 – The effects of metamorphism depend on
the heat and pressure applied to the rock.
 Sedimentary shale can become the following as
more heat and pressure are applied.

2. Nonfoliated – mineral grains are not arranged in bands.
 Commonly made of _______________ or a _____________
minerals.

________________ _____________________ reforms into
quartzite, where the mineral _________________ have
grown larger.
When ______________________ undergoes metamorphism,
______________ crystals become larger and form
