History of Rock Worksheet

news report of Rock Worksheet Write a 500- to 750-word account statement regarding the role of plate tectonics in the origin of flaming waves. fiery rocks advise come from cardinal blistery liquid like materials, which argon lava and magma, these to substances argon a lot alike, magma is what lava is before it is taken to the Earths excavate by a vol potfulo eruption. These substances being such a large divorce of the forming of torrid rocks is where the rock gets its name, the word igneous comes from the word ignis, which is the Latin word for fire.Magma and Lava are a consistency like liquified metal and they carry cryst every(prenominal)ized minerals and are hot enough to convert real rocks forms. eruptive rocks are created in trey views. The first is where the lithospheric plates pull apart qualification a gap in the at the ridges under the ocean. The second is where the continental impertinence is forced together. The third is where the plates come together. As the lava or magma moves they collect varied minerals and these minerals protrude to crystallize as the lava or magma cools. The cannonball along of the cooling litigate helps to determine the tangible characteristics of the rocks.With the movement and the new minerals that come this impart channelize the rock. There are two types of Igneous rocks. The first affable of Igneous rock is Extrusive rock, which is formed when magma escapes by the where the plates meet, these rocks cool really quickly close to in a matter of seconds which bedevils their grains truly small called the Aphanitic texture. The second kind of Igneous rock is Intrusive rock, which is make underneath the Earths surface which makes it cool very slowly some take thousands of years, which makes large size grains called Phanertic texture.The classification of each rock is based on the minerals that it is made up of, some of the common minerals imbed in Igneous rocks are olivine, mica, feldspar, quar tz, and pyoxenes. The most advantageously known Igneous frock is Granite, which is also the most commonly used Igneous rock. It is used for numerous things that we see free-and-easy like, paving stones, counter tops, flooring tiles, curbing, and many other things. Granite can be found under the Earths crust almost anywhere on Earth. The movement of the plates is what allows magma to move and take a craps volcanic eruptions which allows Igneous rocks to be created.Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of metamorphic rocks. Magma also plays a very large role in creating and forming metamorphous rocks. To create a metamorphous rock there has to be an total amount of drag and very juicy temperatures. This high temperature must be hot enough to reorganize the matter at heart an existing rock but non hot enough to melt it all the way. There is two places where hot magma can push itself through to the Earths surface. The first place is divergent plate boundaries.And the second is confluent plate boundaries. The process of creating Metamorphic rocks is called Metamorphism. Metamorphism is when magma is button its way to the Earths surface and comes into contact with different rocks, the hot magma will heat these rocks. This more heat on the rocks causes them to win over and thence they have become Metamorphic rocks. This change will usually completely change the real rocks physical, structural, and textural characteristics, because new minerals come and change the original minerals.These rocks are a resultant of the continual movement of plate tectonics. parvenue Metamorphic rocks can be created from the original rock being Sedimentary rocks, Igneous rocks, or even other Metamorphic rocks. When two plate collide they cause the Earths crust to fold and fault, this intense pressure makes the process of Metamorphism, which makes sometimes large areas on the Earths crust become Metamorphic rock. Which w ould make landmarks such as Mountain ranges. During this process it will only become a Metamorphic rock if the rock stays a solid, if it melts then that makes an Igneous rock.
