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

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 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‚

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

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

STATEMENT: geologists classify rocks based on how the rocks were formed. Rocks can be classified into three categories on the basis of their formation: igneous rocks‚ sedimentary rocks and metamorphic rocks. I. The first type is igneous rocks (from the Greek word for fire) which are formed from molten rock (magma) and lava. A. Formation 1.coming up of magma through cracks 2. forming a layer on surface or filling other cracks 3. cooling forming a very hard igneous rock 4. magma on the surface

Three Types of Rocks: There are three types of rocks and these three types of rocks are igneous‚ metamorphic‚ and sedimentary. These rocks all form differently. These rocks all can be made into another type of rock but they all are different and have probably been many different types of rocks. Igneous rocks form from cooling lava or magma. Igneous rocks that cool from lava have a much shorter cooling time than rocks that cool from magma‚ this is because magma is underneath the earths surface

be no rocks or plate boundaries. Every living thing on earth would have to adapt to these types of things‚ if there even was living things on earth. The different types of rocks like igneous‚ sedimentary‚ and metamorphic have to go through a process to become that type of rock. Igneous is formed when magma is cooled and hardens. Metamorphic rocks are the exact opposite‚ the rock is formed under the earth’s surface‚ when heat and pressure are added. Lastly‚ sedimentary rocks are formed
