Earth’s natural occurrences. From volcanoes to earthquakes plate tectonics play are large role. Another natural occurrence that is not is discussed as much as volcanoes and earthquakes is the formation of sedimentary rock. Plate tectonics also plays a major role in the formation of this type of rock. Plate tectonics is a term that is used to describe how the different plates that make up the Earth move and the reactions that occur as they are moving. Before explaining how plate tectonics are related

Metamorphic rocks are originated within the earths crust. Metamorphic rocks are created when both pressure and heat meet at the right time. During metamorphosis the rocks do not melt the heat and pressure just change the make-up of the rock. There are two types of metamorphosis low grade and high grade. Low grade metamorphosis occurs at 400 degrees C and 400MPa‚ while high grade is anything above 400 degrees c and 400MPa. Once the temperature reaches a little over 600 degrees Celsius and over 600MPa

Minerals and Rocks Minerals Minerals: Minerals are elements or compounds found in the earth. The elements or compounds are called minerals if they have five features. They are solids. They are formed naturally in the earth. They have the same chemical makeup throughout They are not alive or made of living things. They have definite arrangement of atoms. 3‚000 different minerals are found in the earth. Some are common but most are rare. Aluminum‚ quartz‚ feldspar

Metamorphic Rock Metamorphism means to change form; this is exactly what metamorphic rocks do. This paper will take a look at the Earth’s rock cycle to examine exactly where the metamorphic rock fits into it. It will also look at how metamorphic rocks are formed and the relationship between metamorphic rocks and igneous rock and sedimentary rocks. This paper will examine the geological characteristics and materials of metamorphic rocks‚ and examine some examples of metamorphic rocks and will describe

A joint is defined as a fracture in a rock between the sides of which there is no observable relative movement. They are present is most consolidated rocks of igneous‚ metamorphic and sedimentary origin. Joints may form as a result of either diastrophism or contraction. Description: (i) A series of parallel joints is called a ’joint set’. (ii) Two or more joint sets intersecting each other produce a ’joint system’. (iii) Two sets of joints nearly at right angles to one another‚ produced by the

Metamorphic rocks are the transformation of the existing rocks‚ the protolith through the process of metamorphism. The Protoliths can be the igneous rock‚ sedimentary rock or any old metamorphic rock. Due to severe heat and pressure‚ the protolithis get various chemical or physical changes. These rocks create a huge part of the Earth’s crust and these can be classified by the mineral and chemical assemblage and by the textures. Examples of the metamorphic rocks are: slate‚ gneiss‚ schist‚ marble

Level Material History of Rock Worksheet Leah Bechtel 12/09/2012 SCI/245 Robert Dillon Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. The role of plate tectonics in the origin of igneous rock is extremely important. Igneous rock is formed from magma that reaches the continental and oceanic crust or through hot spots that are around the world. There are three different places where igneous rocks can form; where the lithospheric

1. Igneous Iggy was a shortstop playing for the Seattle Sedimentaries.. 2. He was a 10 year pro and hit 46 Rbi’s‚ and 15 Homeruns during his last season. 3. Over this time‚ Igneous Iggy experienced weathering and erosion‚ and compaction and cementation. 4. He also dramatically improved his batting and fielding skills and became known as Sedimentary Steve. C. Sedimentary Steve 1. He is now a 50 year pro now playing for

There are three main rock types present in Ireland: Igneous‚ sedimentary and metamorphic. Igneous rocks are rocks which have crystallized from molten rock. Sedimentary rocks are rocks which have formed due to the gradual accumulation of sediment. Metamorphic rocks are rocks which have once existed as igneous or sedimentary rocks but changed due to great heat or pressure. Over the course of my essay‚ I will account for five rocks found in Ireland and there probable rock forming conditions. Granite

Sedimentary Rocks Define 2 types of weathering? • Mechanical: breaking rocks into smaller chunks o Sediment: clasts (particles or sediment) • Chemical: dissolve mierals or change rock chemistry and make new minerals o Sediment: Ions in solution Which type would result in a conglomerate? • Mechanical. What are the compositions and depositional environments of Coal and Halite? • Coal: o Comp.: plant material o Dep. Environ.: Swamp • Halite: o Comp: NaCl o Dep. Environ.: desert‚
