chemical and structural adjustments in solid rocks to physical and chemical conditions which have been imposed due to changes in pressure and temperature or both. Metamorphism occurs below the surface zones of weathering and cementation. Conditions of metamorphism differ from the conditions under which the rocks in question were originally formed. Metamorphism produced as a result of the progressive increase in temperature and pressure‚ i.e. by burial of a rock within the earth‚ is termed prograde metamorphism

First off you should know what a rock cycle is. The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary‚ metamorphic‚ and igneous. Rocks make rocks. The cycle begins within the core of the earth. The molten rock in the core of the earth is called magma. Once the rock is forced to the earth’s lithosphere or crust‚ the molten rock becomes lava and thereby begins its long journey of development

A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior

Due to the discovery of shock metamorphism rocks (suevite breccia) and melted original rocks scattering in the southern area of Bukit Bunuh‚ it was suspected that the area had the possibility of being impacted by meteorite. The founded boulders made the archaeologists from the Centre for Global Archaeological Research (CGAR) of Universiti Sains Malaysia (USM) to propose of the possibility of Bukit Bunuh as a meteorite impact site. This proposal was led to intense research in the area by utilizing

modes associated with them‚such as symmetric and asymmetric stretches‚bends‚ rocks‚ and tortional modes. For MRZ‚ the C-H stretching Vibrations are observed at 3057‚ 3043‚ 3016 and 2999 cm-1. The asymmetric and symmetric stretching bands of CH2 are observed in the range from 2900 to 2700 cm-1 and this stretching band is mainly coupled with the CH3 stretching vibration. Mirtazapine has only one CH3 group. The C-H stretching vibrations of methyl are observed between 3000 and 2900 cm-1. A methyl group

A Historical Book Review of Glenn C. Altschuler’s All Shook Up: How Rock ‘N’ Roll Changed America By Stacey Peterik Music has been a huge part of history since it began back in prehistoric times. As the decades have passed‚ music has gradually changed to include a variety of different styles; each being influenced in some way by the early blues and rhythm and blues of the 1940’s and 1950’s. As it does currently‚ in that time period‚ music created many conflicts between generations. Also in those decades though

intrusive rocks harden slowly beneath the surface of the earth‚ and often form large mineral crystals within the rock. Granite is a good example of an intrusive rock.Porphyritic intrusive rocks have large crystals embedded in a matrix of smaller crystals. Pegmatite is the only porphyritic rock on the Science Olympiad list.Extrusive rocks harden quickly during a volcanic eruption and are usually smooth-grained. Basalt is the most common form of extrusive rock. |IgneousName |Classification|Description

SKILLS VS KNOWLEDGE In this present age‚ all around the world‚ the illusion that a student is "smart" by the information he remembers from the teachers or from books he reads has been employed by our educational system which leaves the mere skillful person in a lower class in the society. Students are now compared to other students by standardized test which rate your knowledge on what you remember and not what you know or can do. This educational system is not good enough for everyone to benefit
