The deeper the thrill is buried the hotter it nabs, and the higher the pressure becomes. Eventually, rock candy must set up to the new conditions, whether it is baked, or squeezed, or both, and in the affect becomes a metamorphic rock. [pic] The temperature is going up because the center of the earth is molten, and the closer we get to that heat the hotter it gets. This initiate in temperature wit h attainment is called the geothermic gradient.      In the phase draw shown above, temperature increases to the right and pressure and depth increased downward. The arrow is the geothermic gradient. Observe on the out-of-the-way(prenominal) right that the temperature becomes hot enough to melting the rock.

TYPES The metamorphic rocks argon of following types which have been dominating during the process of transformation ? butt on/thermic metamorphic rocks ? high-power metamorphic rocks ? Thermodynamic metamorphic rocks Contact Metamorphism Contact metamorphism is the remark given to the pitchs that take place when magma is injected in to the environ solid rock (country rock). T! he changes that occur are greatest wherever the magma comes into contact with the rock because the temperatures are highest at this boundary and shine with distance from it. impulsive Metamorphism The dynamic metamorphism is a structural change in rock that occurs through excretion of pressure. The minerals do not change chemically and is seen in mountain building where utmost(a) pressure is...If you want to get a full essay, ordering it on our website: OrderEssay.net
