Rocks are intriguing to many individuals all over the world. Being made up of one or even many minerals, rocks draw an overwhelming amount of attention to themselves. When a probe brought back samples of rock from Planet X the task of identifying the rock was assigned. With no prior knowledge of the type of rock presented one will need figure out the identity of the rock based only on its density and physical properties. With an experimental process, one will begin to compare and uncover the identity of the rock samples brought back. To begin with, is the experimental process used to determine the identity of the rock. In doing so one will need to discover the density of the rock. By measuring the rock sample with grams per milliliter is a way used to figure out the density. In starting one will need to measure the mass of the rock using grams. Then using a set milliliter amount of a liquid substance, such as water, one will place the rock sample inside. By reading the new volume of the liquid substance amount one will then subtract the initial milliliter amount from the final volume reading, thus giving you the volume of the rock sample. Using the mass of the sample rock obtained one will then divide the final volume reading unveiling the density of the …show more content…
With the discovery of the rocks density, as shown in Document B, as being 2.64 grams one can now compare it to other rocks. In comparing the sample rock to common rocks the density is very similar and close to many of the common rocks in the chart given in Document A. The density of the rock found on Planet X can vary in impure varieties as stated in Document B. Physical properties of the sample rock are color, which is clear in its pure form, the melting point of one thousand six hundred and forty eight degrees celsius, and that is it not soluble to water, all of which are presented in Document
We walked along the beach a little more and talked and looked at the location of a whale skull that used to be buried in the sand. The rock was actually much smoother than . We also took a look at some possible bones and skeletal remains along with concretions. The concretions were rather large comparable to smart car in size. Concretions are solid masses formed around some type of matter that will change the chemistry of the rock slightly, helping it become harder and less susceptible to erosion.
The minerals were not obvious in hand sample so further mineralogical analysis would likely be needed to recognize the accessory minerals. The Cordell unit is difficult to distinguish in the field from the lower Engadine unit, the Rockview, due to the high degree of dolomitization and recrystallization. However, unlike the Rockview, the Cordell member is more thinly bedded and fossiliferous and lacks algal mats. The bottom of the Rockview dolostones appear to weather to a lighter color than that of the exposed Cordell and is considered
This contains unique frequencies ( measured in terahertz), which geologists use to find what minerals are present within a rock, as different elements have unique frequencies. For example, gold with a depth of 23 nanometres ( a millionth of a meter) will
To find the density of the three coins, I followed a short and simple procedure. First, I used the triple beam balance to find the mass of each coin to the nearest tenth of a gram. Next, I filled the graduated cylinder with 50 mL of water. Then I put the quarter in the graduated cylinder. In my data table, I recorded the volume of the quarter and the the water in the graduated cylinder.
Four to six cores were collected from the nine transects. After the cores were taken, the scientists then examined the weight, grain size, carbonate content, and organic matter content of each sample. Along with this,
The Tapeats Sandstone displays a basal transgressive sequence that built up as the ocean transgressed onto land. The sea transgressed so far into the Grand Canyon that shale deposited over the sandstone, and eventually the limestone was deposited over the shale. The vertical sequence of sandstone, shale, and limestone creates a transgressive facies pattern and displays offshore facies. By looking at these layer patterns, geologists are able to figure out if sea levels were rising or dropping during the formation of these rocks.
In the first paragraph, he explains how the rocks came to be, the article reading, “The rocks visible…were formed from the hard shells of animals that lived in one of these seas.” The author isn’t trying to bring his own opinions about the rocks of the caverns and how ‘magical’ or ‘cool’ he might find them; he simply wanted to teach others about what could be found in the caverns. Vernon also said in paragraph 8, “…about 450 tons of rock is carried away dissolved in water... how cavernous the rock must be.” This suggests that the author felt intimidated by the caverns and its intense features.
For example, experts say, “The three sets of rocks are differentiated on the basis of not only stratigraphic position, but also age, rock types, and overall geologic setting in which they form.” One of the types of rocks found there are crystalline rocks which are exposed near the bottom of the canyon. Another type is sedimentary and volcanic rocks found in the coastal basins which tilted when the continents split apart. Lastly, the Paleozoic rocks at 3,000-4,000 ft. which is flat-lying sediment rocks that create the “stair step” canyon.
The latest data from the Mars Curiosity Rover suggests that Mars had a continental crust similar to the one Earth has. Researchers analyzed data collected with the rover’s ChemCam instrument (short for Chemistry and Camera) and determined that the composition of the rocks on Mars was reminiscent of Earth’s crust. Mars More Like Earth Than Ever The new evidence from the Mars Curiosity Rover supports the notion that many scientists have held lately, that Mars was once much more like Earth than previously thought. Because of what researchers had previously known of the Martian surface, that it was covered in dark igneous rocks similar to the ones that make up the underwater crust of the Earth, Mars was thought of as being a basaltic planet.
It is also "considered to be the world's most complete man-made collection of minerals, fossils, shells, and petrifications in one place. " The total value of all the rocks and
Finally, scientists have unraveled the mysteries of the dark streaks alongside the hilly slopes of Mars. In the article “NASA Confirms Evidence That Liquid Water in Today’s Mars.” by Gina Anderson, talks about the finding of Hydrated salts causing recurring slope lines to darken. The results show that hydrated salts composing of water molecules was the cause of the dark streaks left on Mars. Through the understanding of Hydrated salts, it showed some type of proof that water molecules were left behind; allowing scientists to monitor them.
In order to gain further insight to the theory, the archaeologists in the experiment used limestone located in Cedar Mesa and boiled it to test out the temperature in which it would begin to calcine. The results then determined that the temperature required
In 1980, physicist Luis Alvarez and his son geologist Walter Alvarez proposed the theory that a cosmic impact from an asteroid or comet provoked the Cretaceous-Tertiary Mass Extinction. Scientists later on found hints of an asteroid collision when they noticed an inordinate crater, more than 180 kilometers wide, near the town of Chicxulub in Mexico. This collision was omnipotent in strength, as it would have released as much energy as 100 trillion tons of TNT (Choi, “Asteroid Impact That Killed the Dinosaurs: New Evidence”). The asteroid impact was found to have materialized 65 million years ago, concurring with the Cretaceous-Tertiary Mass Extinction. Moreover, both iridium, a metal typically scarce on Earth’s crust but more prevalent in asteroids and magma deep within the planet, and impact ejecta, matter ejected out of a crater by an erupting volcano or during a meteorite impact, were found in anomalously high amounts in the thin worldwide layer of clay which marked the Cretaceous-Tertiary Boundary.
The Apollo missions were such a phenomenal feat in mankind’s ability to go above and beyond in exploration. One of the main reasons behind the Apollo missions was to be able to get a man on the moon, and bring back samples for further studies. Through recent studies done on these samples that were recovered from the missions, scientists have been able to determine a better understanding of the moons makeup and size. The Authors determined that “On the basis of these high-resolution models, it has been estimated that 70 to 90% of the Moon is derived from Theia” (Wiechert et al. 345).
Seismic facies analysis Seismic facies represent a group of seismic amplitude variations with characteristics that distinctly differ from those of other facies. A seismic facies is the manifestation of the underlying geologic facies or structural feature in the seismic amplitude data. These can be searched and identified from the seismic data by different approaches. These could be based on analysis of either the seismic waveforms or the seismic attributes. Seismic facies analysis consists of the parameters and reflection
