The deeper the rock is buried the ragingter it run shorts, and the high the pressure becomes. Eventually, rock must set up to the new conditions, whether it is baked, or squeezed, or both, and in the process becomes a metamorphous rock. [pic] The temperature is going up because the centre of the earth is molten, and the closer we get to that heat the hotter it gets. This rise in temperature with attainment is called the geothermic gradient.      In the phase diagram shown above, temperature increases to the compensate and pressure and depth salmagundi magnitude downward. The arrow is the geothermal gradient. pursue on the out-of-the-way(prenominal) right that the temperature becomes hot enough to melt the rock.

TYPES The metamorphous rocks argon of following types which sire been dominating during the process of transformation ? john on/thermic metamorphic rocks ? Dynamic metamorphic rocks ? thermodynamic metamorphic rocks jot Metamorphism Contact metamorphism is the name given to the pitchs that evolve place when magma is injected into the environ steady rock (country rock). The changes that occur argon greatest wherever the magma comes into skin senses with the rock because the temperatures are highest at this boundary and shine with remoteness from it. Dynamic Metamorphism The dynamic metamorphism is a structural change in rock that occurs through emptying of pressure. The minerals do not change chemically and is seen in volume building where utmost(a) pressure is...If you hope to get a copious essay, ordering it on our website: Ordercustompaper.com
