Question 8

An example of a region where mylonites are formed is the:

Accepted Answer

A)  Cascade Range.
B)  mid-oceanic ridges.
C)  San Andreas Fault Zone.
D)  Valles Marianas Rift Zone.
E)  Mendocino Fracture Zone.

Question 9

What is the difference between slate and phyllite?

Accepted Answer

Grain size.Phyllite grains are larger,although they are still too small to be seen.The grains give the rock a glossy or lustrous sheen.

Question 10

A rock with both igneous and high-grade metamorphic characteristics is a(n)____________________.

Question 11

Metamorphism is a physical and chemical change that occurs in such a way that:

Accepted Answer

A)  disequilibrium is reached with the new physical and chemical environment.
B)  a dynamic equilibrium is reached.
C)  equilibrium with the new environment is disturbed.
D)  the rock reaches equilibrium with its new environment.
E)  the rock's chemistry and texture become increasingly unstable.

Question 12

What is metamorphic grade,and present an example of how a rock reaches its metamorphic grade?

Accepted Answer

Metamorphic grade is a term that characterizes the degree to which a rock has undergone metamorphic change.When shale is metamorphosed,chlorite first begins to crystallize at about 200°C.If the metamorphism stops there,the rock will be low grade.If temperatures and pressures increase,new minerals replace chlorite,and if temperatures exceed 500°C,sillimanite will appear.

Question 13

Asbestos was once commonly used for insulation and fireproofing in buildings and building materials,but it was found to be hazardous and is no longer used in construction.

Accepted Answer

A) True 
 B)False

Question 14

Metamorphic rocks are primarily classifi...

Question 15

Describe the characteristics of marble.How does it form,and what is it used for?

Accepted Answer

Marble is metamorphosed of calcite or dolomite with fine to coarse grains.Marble is produced by contact or regional metamorphism of limestone or dolostone.Marble is a common building stone and is used for sculpting.

Question 16

Metamorphic rocks are very common in the crystalline basement rocks of the oldest parts of continents.

A) True 
 B)False
