How Does Metamorphic Rocks Change

Next, these rocks undergo erosion, which is the process of moving sediments from one place to another. Then, these sediments are deposited all at one place and over time they start to converge and cement as layers which are also known as strata. As time keeps going, new sediments deposit and cement together over old ones forming new layers. This is a repetitive process that eventually build up layers to make up a Sedimentary rock. Approximately 40 major sedimentary rock layers exposed in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. As you can see, sedimentary rock formation takes an excessive amount of time.

Ultramafic rocks have special significance, in that they probably are derived from the mantle. They are relatively unstable on the Earth’s surface, and are typically metamorphosed. In nature and in simplistic interpretation, igneous rocks that make up most continental crust typically have a felsic composition (such as rhyolite and granite). The mafic rock basalt is the dominant rock type that makes up most ocean crust. Rocks of intermediate composition are derived from the mixing of continental and oceanic crust (USGS

The tiny pieces of rocks broken off by weathering are called sediment or alluvium. Erosion is the process of transportation of this sediment which on sea cliffs sediments becomes part of the seafloor and is washed away with the waves. The larger rocks that are broken off by sediment as shown in this picture are called scree or talus; scree builds up at the bottom of cliffs as the rocks tumble down, these piles are called scree slopes or talus piles.

Weaker rocks erode easily and is a less resistant rock for example, clay and sand. Clay is an example of impermeable rock and is formed at wet lowland areas.

The rock coquina is originally a sedimentary rock. Sedimentary rocks are made up of sediments. The sediments are formed by the mechanical or chemical activities of the natural activities like running water, blowing wind, glaciers etc. this which causes disintegration and decomposition of the pre-existing rocks. The products of decay are transported to some depositional sites by the natural agencies, where they get deposited and with subsequent compaction form sedimentary rocks (Hefferan, O’Brien, 2010). . The sedimentary rocks usually accumulate under a great variety of conditions. This shows the variation in rock, chemical structure as well as in texture. Weathering is the most important process that operates in the

There was a volcano that had a rock named cool guy. The volcano erupted and cool guy landed is the sea on the way the cool guy weathered to a small pieces. the waves carry it to ukraine. the cool guy had the waves move it to odessa. but do not worry the cool guy is now a sedimentary rock. The cool guy was on the beach but then a kid picked up and throw it in the sea and cool guy went to the usa and the uas was cool but not that cool for cool guy. The waves picked it up and carried cool guy back to Ukraine. the sedimentary rock turned into the igneous rock.

Marble is made up by the regional metamorphism of dolomite and limestone rock. A lot of pressure applied to the limestone over a very long period of time form marble. High temperature and pressure turns limestone crystal into smaller, finer and harder crystals. Extended duration of metamorphism process grows crystal size larger and becomes easily recognizable interlocking

Question 2 (a) - All research activities begin with a question. Research, in its most basic form is the process of answering that question, or questions. Academic research, though, is a systematic process of collecting and analyzing information so that it increases the understanding of the phenomenon under study. For research to be viable across disciplines it must utilize established principles of data collection and analysis the scientific method. The term scientific method refers to a way of investigation or the acquisition of knowledge through the testing of a theory or hypothesis, then working through measurements (observation and empirical notes) to come up with a result, which should prove or disprove the original theory. Thus, the basic method consists of a) formulating a question or hypothesis, b) designing an experiment or means of collecting data, c) observation or experimentation, d) analyzing the results and considering the proof or disproof of the hypotheses, and e) suggestions for future research. By the very nature of geology, much of the research method revolves around field observations. This is required because of the nature of the large amount of material that is unable to be transported to the laboratory with the exception of samples.

1. Sedimentary rocks are made from different pieces of rocks and sediments. This happened through the process of erosion and weathering. Every now and then animals get buried under sediments and formed with the rock. As the tissues decay, the bone stay preserved in the rock because of the carbon that release from the corpse. Sedimentary rocks can tell scientists about the fossil's habitat by the size and formation of the rock. For example, one direction ripple marks indicate that the rock formed under a river while ripple marks that move back and forth indicate the rock is formed in an ocean. If a fossil is found in a rock that has one direction ripple marks it is most likely that the animal might have once lived in a river.

Tectonic processes highly relate to the erosion process as the processes control the erosion rates and distributions at the Earth's surface. Tectonic can either raise or lower the surface of Earth, such as creation of mountain or surrounding areas. As a result, gradients of the land surface would be changed. Erosion rates are sensitive to changes of local slope, this will change erosion rates in the uplifted area. More unweathered rock are brought towards the surface if tectonics are actively change. Therefore, erosion changes frequently.

Metamorphic rocks are rocks that have changed due to temperature and pressure change. Therefore Igneous and Sedimentary and other metamorphic rocks can help form Metamorphic rocks. Since Divergent and Convergent boundaries form Igneous rocks when temperature and pressure change the rock forms into a Metamorphic rock. There are two types of Metamorphic rocks, Contact Metamorphism and Regional Metamorphism. Contact Metamorphism results from high temperature which causes the rock minerals and texture to change because of the contact with magma and is associated more with igneous, intrusive rocks. Regional Metamorphism results in subduction zones, subduction zones are usually in Convergent boundaries, so therefore the movement of plates also helps form Regional Metamorphism. In addition this type of Metamorphism leads to the rock minerals and texture changing due to the heat and pressure in a wide region. This becomes a chain for the formation of rocks. Convection, plate boundaries, formation of igneous rocks, heat and pressure, formation of Contact/Regional Metamorphism. Which is why Contact and Regional Metamorphism is also tied with

The rocks and minerals will change because it is being stressed by the increased heat, pressure and chemical changes. The increased heat will melt the

Two main factors influence a volcano’s lava: silica content and gas content. Silica makes lava more thick and sticky, as I learned in my textbook, while gases in lava create more explosive eruptions. Together, these two factors create a wide range of lava types, from the thin and runny lava of shield volcanoes to the gaseous, flammable lava of fire fountains. Lava with high gas and silica content, meanwhile, fuels explosive stratovolcanoes such as Mt. Saint Helens. Along with several types of volcanoes, lava also forms a wide variety of rocks, known as igneous rocks. Different types of lava or magma cool in different locations, creating rocks that range from lightweight pumice and glassy obsidian to rough granite. In the igneous rocks lab, we learned how the crystals that form as magma cools lead to the creation of rocks such as these. The longer magma or lava takes to cool, the more crystals it develops, and the more coarse-grained it becomes. Granite, for example, has a longer cooling process that makes it rugged and rough in texture, whereas obsidian cools so quickly that it forms almost no crystals at all! The differences in igneous rocks can primarily be attributed to the type of magma or lava that formed them and the where they formed. An igneous rock formed on the surface, for instance, would generally have fewer crystals than one that slowly cooled

     Metamorphic rocks are pre-existing rocks that are changed by heat and pressure. The pre-existing rock is called the parent rock, or protolith. Metamorphism occurs in these rocks when the minerals become instable. There are two types of metamorphism, contact and regional. Contact is high temperature, low pressure. It is basically a massive rock that is baked. Regional is high pressure and low temperature. Strong fabric, or layering, develops from

change in mean elevation. The erosional removal of rock on the crust results in an isotactic
