The Characteristics Of Rocks And Rocks

In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk

The collection of the rocks was based on just picking up the most amount of difference looking rocks that was possible and bringing them home to analyze. This was done for about two months from many difference locations including campgrounds, beaches, rivers, highways as well as construction sites. After about two months there were many rocks so I started to analyze and take out the rocks that were of the same kind. I found many granite, basalt and conglomerate rocks.

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.

Despite a family history of geophysicists and rock enthusiasts, I’ve never found the subject of rocks particularly fascinating. However, an exploration of Earth Science has lead me to the discovery that rocks are actually hidden gems (often literally), and that there’s more to the topic than one would think.

2. Use the geologic definition of a mineral to determine which of the items listed in Figure 1.1 (p.3 lab book) are minerals and which are not minerals. Put an “X” in the appropriate box.

Next, we can see that the rock displays a subtle porphyritic texture with plagioclase comprising the phenocrysts. The overall texture of the surrounding groundmass is granoblastic equigranular. Under thin section we also see a weakly defined foliation evidenced in the preferential alignment of actinolite grains and to a lesser extent chlorite grains. Undulose extinction is also observed in quartz indicating the rock was subject to deformation. The normalized quartz, alkali-feldspar, and plagioclase (QAP) values of this rock indicate that it is classified as a grano-diorite according to the IUGS QAPF classification system which is consistent with the hand sample interpretation.

Rocks: Students learn about rocks through the use of a film. The student uses a white board to take notes, and organizes notes with the use of a graphic organizer.

1. Decide if the mineral is metallic or non-metallic based on its luster and streak.

With volume and mass determined, the density formula (d = m/V) was used to determine the densities of each rock and recorded in g/ml.

4. Choose one of the geological periods listed in figure 3.8 and find out all you can about it. How are rock formations from that period identified? What are its most characteristic fossils? Where are the best samples of rock from your chosen period?

If you’re anything like me and you see this painting of “The Rock” by Peter Blume (1944), you may wonder what in the world is going on in the picture. At our first look, we see the obvious; the enormous rock Peter Blume placed right in the center. After looking at the scenery going on, I think that the placement and size of the rock is proportioned that way as a sign of it being significant. The way I see it, the monument plays an important role when it comes down to determining why there are so many things going on at once in the painting. With the comparison of the details of the hard working people to the broken rock, half built building, and the smoke, I will establish the reasons of why this picture shows both destruction and loyalty- and the ways destruction in this painting also results in uniting the people working.

Some rock’s in the Earth’s interior that are solid, are so hot that, if the pressure on these were released, or they are convected into a lower pressure zone, they could begin to melt

The Grand Canyon’s display of layered rocks is magnificent and immense. The Canyon has many types of rocks including metamorphic, igneous and sedimentary. 2 billion years ago, igneous and metamorphic rocks formed in the inner gorge of the Grand Canyon. On top of these rocks sedimentary rock layers were created. Over time these layers of rocks transformed with erosion, tectonic actions, intrusions, and uncomformities.

A mineral is a naturally substance that happens, in this process an inorganic material creates a solid crystal like material that has a specific chemical composition. All the matters that make up a mineral are natural and made up from the earth and do not have living matter in them. The structure makes it three dimensional, which means that it has a particular shape that repeats itself. Now compared to a rock, which is also an inorganic material, however it has not certain atomic structure compared to minerals. Rocks are made up of several different minerals, which have been “stuck” together in a geological process that formed

     Rocks are classified to make it easier on people to identify them in the future. This can be done by a numerous amount of ways. Each rock type has their own specific ways, but there are two distinct characteristics that apply to all. These are texture and composition. These two, along with many others helps to classify igneous, sedimentary, and metamorphic rocks.
