Answer 1

1: Answer: D) The degree Or grade of metamorphism.

The metamorphic rock shows different types of texture and different metamorphic rock has different minerals composition so with increasing grade of metamorphism the minerals contents within the rock changes and shows different texture. So the metamorphic rock and texture signify the degree and grade of metamorphism. The age of the rock determined by fossil content (relative age ) and by radiometric dating (absolute age). Text distance the grain has travel is determined by the sorting and roundness of the grains. When metamorphism occur don't defined by texture and mineralogy.

2: Answer:B) The rock cycle

The rock cycle is the process where the rock of one type changes to rock of another type through the geologic time and it's a repeating cycle. Conservation of energy means total amount of energy in an isolated system remain constant and conservation of mass means constant mass. Energy flow signify that the energy flow from one place to another and one state to another state.

3:Answer:E) Regional

Regional metamorphism is characterized by the process where the texture and mineralogy changes over a large area due to deep burial and heating mean changes of the pressure and temperature also the large scale plate tectonics(mountain building process).

Contact metamorphism is defines a type of metamorphism where the texture and minerals of the rock changed by heat due to contact with magma. Burial metamorphism is a type of metamorphism which defines that when the sedimentary rock buried and undergone diagenesis due to pressure and temperature. Hydrothermal metamorphism is a type of metamorphism where the rocks comes contacts with the hot chemically active liquid type mean water bearing magma. Impact metamorphism defines the type of metamorphism of shock related metamorphism where rock suffer impacted event.

4: Answer:Burial

Burial metamorphism defines the type of metamorphism where sedimentary rock has buried and undergone diagenesis due to pressure and temperature of the overlaying rocks, here the metamorphism is low grade and sedimentary rock is very thick accumulation.
