What have we learned so far in science class. So far in science class we have learned about astronomy, geology, oceanography, and the rock cycle. Astronomy is the study of the universe .Geology is the study of earths physical features. And oceanography is the study of the earths ocean. The rock cycle is the study of rocks and how they form. The different types of rocks There are different types of rocks in the world today. All the rocks are put into three different categories. The Three rock categories are Igneous, Metamorphic and Sediment rocks. Igneous rocks are formed when the cooling of and the solidification of magma or lava. The igneous rock is a glassy of crystalline type of rock. The molten is usually between 1,100-2,400 degrees Fahrenheit. Metamorphic rocks are formed when the …show more content…
Sediment rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area. We also watched the San Andreas movies that just came out. The San Andreas movie was about people living in California and one day the San Andreas fault tectonic plate had an earthquake. After the earthquake scientists tried to see if they could tell when another on was going to happened. The scientists radar had said that there will be another earthquake in a few minutes and there was one. The scientists were in a building and they radar said that they were going to have another one but it was going to be a really big earthquake. The scientists said the earthquake was going to be so big that the people on the east coast of the world will be able to feel it. Meanwhile there is this one family that is broken up but they have to forget what had happened in the to save their daughter. Their daughter is in
Ultimately the development of previous inferences and observations which have developed our current model for the Earth’s composition and interior structure are a key concept in understanding our future developments towards resourcing our planet and understanding how it works to a further degree.
Quartzite is a non-foliated metamorphic rock. This rock is intrusive and forms when exposed to extreme amounts of heat and pressure. Over a billion years ago, there was an ocean where Kamiak Butte is. This ocean floor was made of sand, as time went on oceans receded and the exposed sand underwent processes that turned it into sandstone – or as we learned in class the process of lithification. Years later, this sandstone would morph into the quartzite that is present now.2
More recently than Zeck’s work, Cesare et al. (1997), only divided the xenoliths into two main types: garnet-biotite-sillimanite and spinel-cordierite xenoliths. The quartz-cordierite rocks, distinguished by Zeck (1970), were interpreted as the products of interaction between garnet-biotite-sillimanite xenoliths and blebs of mafic magma and are not recognised. The xenoliths were observed to contain widespread occurrences of rhyolitic glass as...
and Metamorphic rocks can be found. There are also a lot of crusted plates, and violent
This field report is for anyone that is interested in the effects of running water in the North Fork Cosumnes River California.
Basalt forms due to the partial melting of the layer of the mantle called the asthenosphere. The asthenosphere is the plastic zone of the mantle beneath the rigid lithosphere. Mantle plumes coming from the mesosphere can cause the asthenosphere to melt with heat or even if pressure decreases, which is called decompression melting (Richard 2011). The magma that forms from this melting is mafic magma that solidifies once it reaches the earth’s surface and cools quickly. The above process mainly occurs mainly during intraplate igneous activity which is the main explanation for volcanic activity that occurs a long distance away from a plate boundary. If the tectonic plate above the mantle plume is moving it can create a string of volcanic activity such as in Hawaii. See Fig 2.
Convection currents deep in the mantle of the earth, begin to well up towards the surface. As the pressure increases, it sets the crustal plates in motion. There are different kinds of mountains - Volcanic, Folded, Fault-block, and Dome mountains. Volcanic mountains are formed when magma comes up through cracks in the Earth’s crust and explodes out of lava and ash. The Hawaiian volcanoes, Mt. Hood, Mt. Etna, Vesuvius, and Mt. Saint Helens is an example of volcanic mountains.
The first misconception, that all rocks are formed the same and are composed of the same materials was put to rest when we explained to students that sedimentary rocks are formed from by pressure and time and are made up of many types of materials such as mud, sand, pebbles, bones, etc. This became more concrete for the students when we had them create their own rock out of different sediments (starbust and sour patch kids). This also put to rest the other misconception that the streaks on the rock are just its color and nothing else. The students realized by applying pressure to the starburst and having it form into one that the streaks were the result of the different sediments forming
Crystalline silica may be of several distinct types. Quartz, a form of silica and the most common mineral in the earth's crust, is associated with many types of rock. Other types of silica include cristobalite and tridymite.
Science is the body of organized knowledge. Science is the collection of ideas and theories and the methodology used by people to prove them. It is the set of methods that people follow in order to explain the things that they see, the things that they perceive and the things that they believe in.
Science is the observation of natural events and conditions in order to discover facts about them and to formulate laws and principles based on these facts. Academic Press Dictionary of Science & Technology --------------------------------------------------------------------- Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts (data).
The field of geology has many different branches. Some of these areas have hardly anything in common. The one thing that they all include, though, is that each one concentrates on some part of the Earth, its makeup, or that of other planets. Mineralogy, the study of minerals above the Earth and in its crust, is different from Petrology, the st...
Volcanoes are formed when magma is expelled from the Earth’s surface, resulting in volcanic eruptions consisting of ash and lava. Over time, the lava cools and forms into rock on the Earth’s surface. Whenever an eruption occurs, the newly-formed rock from the lava layers continuously until the volcano takes its shape. Volcanic eruptions have taken place for thousands of years, and even today, according to the U.S Geological Survey (2010), there are approximately 1500 active volcanoes located throughout the world.
A rock is a naturally occurring substance or solid material which is composed of one or more minerals. There are three types of rocks namely – Igneous , Metamorphic and Sedimentary rocks. These rock are in a continuous cycle of process whereby they are changed from one type of rocks to another which may or may not be of different mineral composition. This processes is called Rock Cycle. The rock cycle symbolises an ever-changing Earth. The three types of rocks igneous, metamorphic, and sedimentary, record these changes, and it is up to geologists to observe the effects of the changes and try to decipher the clues and develop a history of the Earth. The original concept of the rock cycle is usually attributed to James Hutton, who is also known
Geology is the study of earth processes, materials, and history (What Does A Geologist Do from Geology.com 1). Geologists have a wide range of jobs. They are responsible for the planning of field work and studies, where they observe and collect samples of materials (Duties from bls.gov 1). Different areas of geology have different reasons for doing research (1). However, they all have some things in common. When working in the field, geologists all examine the land, take samples, and make maps and sketches of what they observe (Hammonds 18). After working in the field, geologists take their studies back to the laboratory. Here, they examine and test the samples that they took when in the field (19). When that is done, they take what they learned or observed and put it into writing. Geologists often write reports or papers concerning their studies (19). Most geologists have these three things as part as their jobs.
