Metamorphic

44
Q

transformation of one rock type into another

A

metamorphism

45
Q

Due to changes in pressure and temperature over large region of the crust

A

Regional

46
Q

The rock minerals and textures are changed mainly by head due to contact with magma

A

contact

47
Q

Any planar arrangement of mineral grains or structural features within the rock

A

Foliation

48

Can be arranged in terms of increasing metamorphism and it appeared layered or banded with compressed mineral grains

A

Foliated rocks

49

Chemical

53
Q

Rocks formed from the accumulation of animal debris

A
