Essay On Rock Cycle Of Rock

Rock is an aggregate of one or many rock forming mineral. Rocks and soil are destroyed and formed in a cycle process or called rock cycle. A rock cycle shows interrelationship between the three main types of rocks through internal and external processes. There are three main types of rocks formed in a rock cycle which are known as igneous rocks, Sedimentary rocks and metamorphic rocks. In rock cycle, different kinds of rocks was formed, destroyed and recycled into new rock. The rock cycle will keep going and would not stop (Hirsch, 2015). Each of these rocks contains a variety of individual rock composition or texture that differ them from one another. The rock cycle start with a melted magma that rises toward the surface of the earth. Magma was formed in the mantle. Hirsch (2015) defines that, “a melted rock and gas bubbles will produced hot lava called magma”. Rock melt due a very hot temperature in the mantle and will buoyantly rises toward the surface of the earth for it is less dense than the surrounding rock. Most magma commonly spills from a volcanic eruption. As the magma moves quickly from the super-hot condition of the earth interior to the much cooler environment at the surface, it cools and

Transformation of igneous rock or sedimentary rock into metamorphic rocks involving temperature and pressure changes, it either together or separately (Goodman, 1993). The process is called, metamorphism. Metamorphism will alter the textural, structural and the physical and chemical properties of a rock. As being mentioned, “Meta” means change and “morph” means form, therefore, metamorphic rocks form when mineral reorientation and recrystallization in these rocks form foliation (Johnson & DeGraff, 1988). Temperature and pressure changes from burial deep under the Earth’s surface will alter the molecules of flat minerals which cause by magma and friction of tectonic
