A
What are the two main agents responsible for metamorphism?
Heat and Pressure
What is the texture called when minerals grow freely in all directions without external stress under high heat and low pressure?
Hornfels Texture
The type of sedimentary rocks that form from minerals precipitating out of water.
Chemical sedimentary rocks
What are the 2 main types of igneous rocks?
Intrusive and extrusive
The type of sedimentary rocks primarily formed through the cementation of dissolved weathering rocks
Detrital sedimentary rocks
What are the three broad classes of metamorphism?
Contact, Dislocation/Dynamic, Regional Metamorphism
What are the two most important characteristics that define the textures of sedimentary rocks?
Porosity and packing
Igneous rocks with high silica content are called felsic (acidic) and are usually __________ in color
Light
These are land areas where various types of sediment deposits accumulate.
Continental Environment
Type of fabric where minerals show parallel orientation.
Anisotropic
Give the two types of textures of sedimentary rocks.
Clastic and nonclastic
What is another term for dislocation metamorphism?
Dynamic Metamorphism
What do you call the conversion of coarse-grained sediments to rock?
Cementation
From which two Greek words is the term metamorphism derived?
Meta and Morphe
The main criterion for classifying metamorphic rocks is the presence or absence of ________.
Foliation
Biochemical sedimentary rocks form from minerals that precipitate out of water, while chemical sedimentary rocks are created by organic activity. True or false?
False
Sedimentary rocks are formed deep within the Earth’s crust. True or false?
False
______ is common intrusive igneous rock used for building and monuments.
Granite
Multiple Choice: Which of the following deposits is not considered detrital? a) Terrigenous b) Pyrolastic c) Calcereous d) carbonaceous
d) carbonaceous
When the original rock is known, the prefix used in naming metamorphic rocks is ________.
Meta
What do you call the conversion of muddy sediments to rock?
Compaction
What is the term used to denote the processes that convert sediments into sedimentary rocks?
Diagenesis
True or False:During metamorphism, there may also be a transfer of material at the contact when hot gases from the igneous mass penetrate the country rocks and this process is called pneumatosis.
Pneumatolysis
True or False: Minerals grow according to their crystalline shape and stress direction.
Multiple Choice: Sand-rich metamorphic rocks are described as: a) Pelitic b) Psammitic c) Argillaceous d) Arenaceous
b) Psammitic
