
Define contact metamorphism: _______________________________________________
_________________________________________________________________________

When very hot water reacts with rock and alters its chemistry and mineralogy,
__________________________ metamorphism occurs.
Page 136

Wavy layers and bands of ________________________ characterize _________________
metamorphic rocks. __________pressure during metamorphosis causes
___________________ with flat or ________________ crystals to form with their long axes
perpendicular to the ________________________. 2 most common types of foliated
1
metamorphic rocks are ____________________, which is derived from shale and
_________________ which is derived from __________________________.

___________________________ metamorphic rocks lack ___________________________
with long axes in one direction.

Non-foliated rocks are composed mainly of _____________________ that form with
__________________________________. 2 common examples of non-foliated rocks are
________________________ and __________________________.

Define porphyroblast: _______________________________________________________


How do minerals change without melting? _______________________________________
__________________________________________________________________________

Most metamorphic rocks reflect the original ______________________________________
of the ________________________________. Gneiss, for example, has the same chemical
______________________ as _____________________.
How do valuable ore deposits like gold and copper form? ___________________________
__________________________________________________________________________

What is the rock cycle? _______________________________________________________
__________________________________________________________________________

True or False. Any rock can change into another type of rock.
