A. ROCK CYCLE
Rock cycle is a process in which a rock fused, melted, frozen, and then into rock again.
In the first cycle of rock formed by the shifting plates in the earth's surface. Then this shift produces magma magma where it will push out the earth's surface and at the time the magma melted the surface of the earth, it will be over land through which the liquid magma.
For some time the magma will freeze and turn into cold rock called "Igneous Rock".
Stone will experience due to weathering bebrapa thing diantarnya:
1. Weathering In Physics
Weathering caused by the physics of temperature change is not permanent. example of the heat suddenly become cold and even rain and storms cause rock mold.
2. In Chemical weathering
Is due to weathering caused by chemicals that react with HCL rocks (rock gampinh) resulted in decaying rock, also with the acid rain which reacts with the rocks.
3. In Biological weathering
In addition to weathering which occurs due fisikan and chemical processes, one of weathering that may occur is a biological weathering. One example is the corrosion caused by interference from the roots of large plants. The roots of this large plant capable of making the crack-cracks in rocks and can eventually break rocks into smaller parts again.
Stone occurrence process.
1. Magma undergoing crystallization / freezing will produces IGNEOUS ROCK.
2. IGNEOUS ROCK will experience weathering by water and so will result in sediment.
3. Sediment will also experience Weathering manjadi SEDIMENTARY ROCK.
4. ROCK SDEDIMENTARY changing temperature and very high temperature will be turned to stone of transition.
5. Stone would shift back into the magma and so is so.
STONE TYPES
Igneous 1 (IGNEOUS ROCK)
dalah rock type formed from magma that cooled and hardened, with or without crystallization, either below the surface as intrusive rocks (plutonic) or on the surface as ekstrusif rocks (volcanic).
2. ROCK sediment (SEDIMENTARY ROCK)
Rock sediment or sedimentary rocks are often referred to is rock formed by the process of pembatuan or results lithifikasi weathering and erosion processes which then tertransportasi and so on terendapkan.
3. ROCK TRANSITION (MetaMorph ROCK)
Metamorphic rocks or metamorphic rocks are rocks formed by the process of temperature changes and / or pressure of the rocks that have been there before.
