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

Is Peter the Rock? It is a significant position that divides the Christian religion. For nearly five hundred years‚ Catholics and Protestants have quarreled over the meaning behind a verse in the gospel of Matthew‚ "That thou art Peter‚ and upon this rock I will build my church" (Matt. 16:18‚ KJV). This essay will argue that the Apostle Peter is the rock in the sixteenth chapter of Matthew. It is apparent that Christ gave Peter primacy among the other disciples‚ declaring him the rock to which his

explain how rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks.

THE ROCK CYCLE ● ● ● ● There are three main types of rocks: igneous‚ sedimentary‚ and metamorphic. Each of these types of rocks are formed in different ways and each type of rock can be changed into the other types of rock. This process is called the Rock Cycle. The rock cycle is the process that makes and recycles rocks. IGNEOUS ROCKS ● ● ● ● ● ● Igneous rocks are formed from magma. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface‚ time and weather break the

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

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

The rock cycle is very important to us because it explains the way the different types of rocks are formed on earth. The rocks currently visible on the Earth’s surface have moved through transition stages that transformed them from one form into another. The importance of the rock cycle lies in how it forms and recycles the various layers that make up the Earth. To do this‚ the cycle moves through three different stages that produce three different types of rock. Igneous rock makes up the foundation

Metamorphic Rocks Axia College of the University of Phoenix Metamorphic rock is the transformation of an existing rock type in a process called metamorphism‚ which means change in form. Metamorphic rocks make up a large part of the Earth ’s crust and are classified by texture and by chemical and mineral assemblage (Murck‚ Skinner‚ & Mackenzie‚ 2008). Metamorphic rocks started out as some other type of rock‚ but have been substantially changed from their original igneous‚ sedimentary‚
