LESSON 4 Q2

Question 1

alteration of the composition or structure of rock by heat, pressure, or other natural agents

Answer 1

metamorphism

Question 2

2 factors that involved in the process of metamorphism

Answer 2

temperature
pressure

Question 3

plays a crucial role in the process kf metamorphism. the heat affects the rock chemical composition

Answer 3

temperature

Question 4

various tectonic setting, similar to temperature

Answer 4

pressure

Question 5

the pressure on rock by the weight of overlying material such as in burial metamorphism. this type of pressure is the same in all direction and makes the rocks to fracture or deformed

Answer 5

confining pressure

Question 6

force in a particular direction differential pressure is dominant at convergent boundaries.

Answer 6

directed or differential pressure

Question 7

a set of flat or wavy parallel cleavage planes produced by deformation under directed pressures

Answer 7

foliation

Question 8

the dissolve mineral in the fluids react with rocks that fluid peneptrate causing changes in chemical composition and sometimes completely replacing one mineral with another without changing the rocks textures

Answer 8

hydrothermal fluids

Question 9

the alteration process caused by fluids fluids passing through the rock and catalyze chemical reactions

Answer 9

metasomatism

Question 10

caused by hydrothermal fluids also occurs in mid ocean ridges where hot lava, coming out of the fissure

Answer 10

serpentinization

Question 11

type of metamorphism in which both high temperature and high pressure are imposed to large parts of the crust

Answer 11

regional metamorphism

Question 12

a type of metamorphism which is prominent in areas where surrounding rocks are exposed to heat coming from magma intrusion within the layers of the rocks

Answer 12

contact metamorphism

Question 13

a type of metamorphism which takes place when the heat and shock waves from meteor or asteroid impact transform rocks immediately around the impact site

Answer 13

shock metamorphism

Question 14

a type of metamorphism which occurs at lower temperature and pressure which transform sedimentary rocks that has undergone diagenesis into low grade metamorphic rock

Answer 14

burial metamorphism

Question 15

a type of metamorphism which they found in subduction zone anf they are rarely found on the earth surfaces as they formed kn in such a great depth

Answer 15

high pressure metamorphism
