Question

Name a metamorphic rock. how are metamorphic rocks formed

Answer 1

Answer:

Quartize is a metamorphic rock

Metamorphism, mineralogical and structural adjustments of solid rocks to physical and chemical conditions differing from those under which the rocks originally formed. Changes produced by surface conditions such as compaction are usually excluded. The most important agents of metamorphism include temperature, pressure, and fluids. Equally as significant are changes in chemical environment that result in two metamorphic processes: (1) mechanical dislocation where a rock is deformed, especially as a consequence of differential stress; and (2) chemical recrystallization where a mineral assemblage becomes out of equilibrium due to temperature and pressure changes and a new mineral assemblage forms.

Answer 2

Answer:

Metamorphic rocks are formed when existing igneous and sedimentary rocjs are changed by great pressure or intensive heat or both.

The name of a metamorphic rock is marble, slate ,gneiss etc.
