Essays on Rocks

Continental drift is the theory which proposes that the world was originally made up of a single continent. With the passage of time, this continent was broken up, and it drifted apart to form the seven continents that are present today. It was proposed by Alfred Wegener whose hypothesis stands that the continents are made up of rocks that rest on the heavier weighing rocks on the crust, and this is a movement that is mimicked by icebergs on water. The continents move rigidly. Plate tectonics theory proposes that the Earth’s surface is actually broken up into a ...

The theory of continental drift assumes that the earth is composed of one continent for billions of years. It slowly drifted apart to form the seven continents which could be recognized in the modern times. The drifting of the continents is mainly due to the lighter rocks at the surface which is influenced or moved by the heavier rocks beneath. On the other hand, the plate-tectonics theory assumes that the earth is composed of plates or slabs which are shifting or moving away or towards each other. The movements of the plate depend on the condition and chemistry of ...

Weathering and erosion are two basic events that take place on earth as part of the wear and tear of the natural resources like rocks, soils, and plants and trees that cover the earth. Closely observing weathering and erosion will help understand how the surface of the planet has been changing over the past several years and how it will change in the future as well. Weathering is the process through which rocks on the surface of the earth gradually break down into small pieces. On the other hand, erosion is the process through which the broken pieces and ...

Risks to the Mine

The major hazards to the mines include the possibility of floods taking place in the sites, and they will lead to a stop of the mining process. Secondly, the mines are prone to gas explosions. The explosions will increase the hole, and might even lead to the prevention of further mining (Khan, et al. 2004). Thirdly, the mines might face chemical leakage, an act that may cause decomposition of rocks and depletion of the important resources in mines. Moreover, mines are prone to dust, that will lead to blocking of the extraction process, by occupying the region, or causing ...

Around the world, there are roughly 1500 potential active volcanos. Most of these volcanoes are around the Pacific Rim also referred to as ‘Ring of Fire.'

Volcanic ash has minerals within it when incorporated into the soil; it adds nutrients.

Volcanic mountain slopes are steep in nature. It makes it inaccessible to both animals and human beings. It provides habitat for rare plant and animal species away from human manipulation. Gases that erupt from volcanoes provide water and atmosphere. Regardless of the slow processes involves I making them it is significant over an extended period. Most volcanoes exist on the brink of tectonic plates. Amongst the tectonic plates, the largest is the Pacific ...

I placed myself on a smooth rock in a crop of trees in order to become more in touch with nature. Disconnecting myself from everything around me other than my senses and the location I began to take in my surroundings. A few birds chirped in the distance; the sound was hollow against the trees around me. A dog barked, further away than the birds. Gray-blue clouds across the horizon from the east, lighting up pink, purple, and red as the sun began to set beyond the rolling green hills in front of me. Nearby I could hear what ...

The current theory regarding the evolution of the earth’s ocean is that water is present during the formation of the earth. Most of the discovered materials which was more than 4 billion years old also contained evidences of the present of water (Genda, 2016). Some scientists suggest that the water on earth emerged in the surface when steam was released in the volcanoes. Additional water emerged in the surface of the earth coming from meteorites and comets during the formation of the earth. The continuous addition of water from volcanoes and meteorites or comets led to the formation ...

Like many other United States National Parks, Badlands is unique unto itself with physical attributes that when they are seen one knows it is Badlands National Park. Located in an area rich with history, the Badlands was created and founded as a national monument in 1939 by President Roosevelt before officially becoming a national park in 1978 (Steiner, 1993). The landscape of buttes, ravines, and hills found in the midst of the prairie of Southwestern South Dakota influenced the Lakota Sioux to call the area, ‘mako sica’ or ‘badlands’ (“South Dakota Legends,” 2003). The Sioux Pine Ridge reservation lies ...

Question 1 Tectonic plate motion refers to the movement of continental and oceanic plates from one place to another due to the effect of forces that generally act on these plates. These movements cause some effects to the surrounding environment and even to the earth surface in general. A scientist by the name of Wegner had earlier on formulated a theory that instituted some of the facts and evidence backing this presence of continental drift that had happened some time back in history (Runcorn, 2013). Furthermore, the critical evidence in support of continental drift is the jigsaw fitness of ...

Hawai'i was the 50th state to join the USA. It comprises 132 islands and is said to be the home of volcanic islands. These islands reside in the Central Pacific Ocean. Moana Loa is one of the top most active volcanoes that had formed the island of Hawaii in the ocean (Networks, 2016). The movement of plate tectonics has resulted in the volcanic eruption and, however, the volcano towering and presence of valleys had a significant impact on the economic value.

Theory of plate tectonics

Plate tectonics theory explains that upper layer of the earth’s surface is segregated into various plates that ...

Thesis

Charles Baudelaire’s poem, The Swan (1860), is a clash of emotions, from nostalgia to despondency, brought about by the destruction of the City of Paris and the memory creation on the events of the war.

The feelings of loss and nostalgia keep on bugging the persona’s mind, and he remembers Andromache, the widow of Hector, a Troy great warrior. When Greece defeated Trojan, the son of Achilles took Andromache as a trophy of war, taking her away from the familiarities of her entire life and surroundings to a new civilization and establishment where she became a wife ...

Virgil perceives an entrance to the underworld as a cave by the shores of Italy consisting of a lake and wood close to the mouth, with a lake inside the cave (Torjussen 73). One can only get through by offering a golden tree branch to the Cocytus ferryman (Solmsen 13). According to the philosopher, there are different kinds of souls in the water that humbly requests assistance in their crossover to the boat. According to Virgil, the only access to the ship is by having the body buried with the alternative being swimming in the smelly waters (Bremmer 185). ...

At one point, different concepts and theories of the natural science meet at an explanation of phenomena in a manner that most scientists may not imagine. Such is the relationship between geology and physics. Geology, definitively, is the study of the composition and elements of earth. In an advanced understanding, geology defines the different aspects of the universe such as rocks and the processes by which they change. On the other hand, physics is the branch of natural science that details the understanding of matter force, energy and matter with their movement through time and space (Anand, 2002). With ...

Psychological studies conducted in the last fifty years have found that social isolation has a profound negative affect on people. This is because humans by nature are social creatures, who need and thrive of off physical and emotional connections. This is one reason that that isolation is used by prisons and in torture as the separation is expected to make the person more likely to conform to expectation. Many people who have been socially isolated for long periods of time begin to experience negative effects such as, hallucinations, high blood pressure, increase in illness, verbal and rational reasoning skills ...

An analysis of the problems associated with the word "Troll" require a study of the words etymology in relation to its origin and the way in which it has evolved and developed throughout the years. An analysis of the research available on the etymology of the word suggests Scandinavian origins that can be traced deep into the Scandinavian folklores. The word "troll" is, therefore, quite ancient as well as complex and contradictory in nature. The various Scandinavian countries identify trolls as mythological creatures in their literary cultures. However, trolls do differ in their nature from the various countries, meaning ...

1.0 Tectonic Setting of South China Hong Kong, which is located near the southeastern margin of the Eurasian Continental Plate (ECP), called the Cathaysia Block, in Southeast China, rests on a stable intraplate region of the ECP some 700 km from its nearest plate boundary, an area that underlies Taiwan and trends southward to the Philippines and northeastward to Japan (Pappin, Koo, Free, & Tsang, 2008). Although stable, this continental intraplate region has been associated with earthquakes in the past as it straddles the northeast-trending Lianhuashan Fault Zone. There are two major fault zones, which trends in the regional northeast ...

Identifying the main problematics of the word "troll requires recalling its etymology, i.e. the very first time when it was used and its transformation over the centuries. An accurate analysis of the specific sources suggests that this word is quite ancient, multi-valued, and most notably, very contradictory. The word has Scandinavian roots and its etymology goes deep into folklore. The word "troll" has a direct relationship with nature because trolls, as mythological creatures, represent nature. On this basis, one can say that trolls from Denmark differ from trolls in Sweden, Norway, and Iceland. Despite the fact that the geographical ...

It is a continuous quality improvement model that is comprised of a logical sequence of the four monotonous steps to make continuous improvement and for learning. The model is considered a continuous feedback loop because it helps to identify and change the components of the process in order to reduce variation. The main aim of the cycle is to plan to do something, checking to evaluate the meeting of all requirements, and rectification of process to get desired results (Ledlow & Coppola, 2013). The four ...

Question 1: Describe the basis of the principle of superposition as well as why we cannot date a 1 million year old hominid with radiocarbon dating. According to Hull (191), the principle of superposition states that for any layers or sequence of surface-deposited material, a bed is older than the one above it and younger than the one below it. However, this is not always the case since rocks and beds can buckle causing younger rocks to go underneath older bed. Therefore, the principle should be applied critically. Basically, the principle states that younger rockers lie on older rocks ( ...

Karen Warren coined the term “Ecofeminism” in explaining the logic of domination where the notion of people’s control over nature as a whole is wrong and for the same reason that the subordination of women to the will of men is also wrong. According to argument, feminists should object to the idea domination because subordination of women and domination over nature both represents the logic of domination. On the other hand, the asserted claim of twin domination encompasses several issues. In this discussion, Warren’s logic of domination and the concept of ecofeminism will be examined by explaining ...

Sinkholes are a problem across the globe, especially in urban areas. Sinkholes can cause damage to roads, collapse structures, and destroy property. The biggest way to prevent a sink hole is to learn what factors are included in the formation a sinkhole is, how a sinkhole forms, and wheatther or not the sinkhole was naturally formed or if humans created the situation that caused the sinkhole in the first place. While it is not possible to actually prevent natural sinkholes, there are several ways that sinkholes which are created from human activity may be prevented, or at least ...

Introduction

A fossil is any substance that evidences a once-living organism (University of Arizona, 2016). As such, fossils evidence the ancient life forms which inhabited the earth long time ago and were preserved by a natural process. Most of the fossils are found in sedimentary rocks formed from the sediments of rivers, seas, and lakes. Some of these fossils are actual remains of living things such as bones, or events that happened in the past, for instance, the dinosaur footprints. However, it is ordinarily the hard parts of organisms that get preserved under the right conditions and the interaction of ...

These events can be social, political, technological, economic, and ecological in nature. Nevertheless, one event can touch all these facets on either a minor or major scale. This paper explores some of the events that shaped human history, and their impacts on modern policymaking. The Chernobyl nuclear disaster of 1986 revolutionized the way industrialized nations ...

The arrival of the British troops in Boston in the year 1768 was a cause of much unrest between the relations of the Americans and the British. The American soldiers were just as disturbed as the American citizens, who were forced to be kept under control by the British rule. America being a British colony at the time was forced to follow the rules and regulation imposed by the British. The unrest that ensued came from the colonists and the ones who were loyal to the British Parliament. As much as the personal strife between the colonists and the ...

Chemical Weathering

Chemical weathering in the mid-latitudes is the process where rocks are weakened and disintegrated by chemical reactions that occur in the soil. Some of the chemical reactions that cause chemical weathering are oxidation, carbonation, and hydrolysis. These processes are involved in either forming or destroying minerals and therefore altering the nature of the mineral composition of the rocks. The process of chemical weathering on rocks characterizes the second stage of rock disintegration. The first process occurs during physical weathering and it involves disintegrating rocks into small pieces which are further broken into smaller pieces by chemical weathering. The most ...

Ernest Rutherford and his contribution in radioactivity

Ernest Rutherford is termed as the Father of Radioactivity and nuclear science. Rutherford, who born in 1871 and passed on in 1937, discovered alpha and beta rays. He set forth the law of radioactive decay, identified the alpha particles as helium nuclei. Rutherford postulated the nuclear structure of an atom. His contribution to Radioactivity came from an experiment he demonstrated by firing alpha particles into gas atoms where few particles were seen to deflect. This implied a dense, positively changed central region of an atom contained an atomic mass (Dardo, 2004). Figure 1. Top: expected results, alpha particles passing ...

One of the most recognized personalities in the world of discovery is Ernest Rutherford. This is due to his efforts in chemistry-related research which led to a number of discoveries. Ernest carried out his education mainly in New Zealand, where he was born and brought up. At first, Rutherford did research into the magnetic properties of iron when exposed to high-frequency oscillations. This made him one ...

Question 1

Radioactivity is the process by which unstable isotopes of elements disintegrate in the nucleus to release energy in form of gamma rays, beta radiation and alpha radiation. The disintegration occurs as a result of the stability within the cell nucleus. Some isotopes of elements have non-balancing number of the protons as compared to the neutrons, as a result of the lack of balance between the negative and the positive charges in the nucleus; the nucleus becomes unstable and disintegrates. Radioactive radiation was first discovered by Henri Becquerel in 1896 as he was working on X-ray. By then the X-ray ...

Introduction

Before the Protestant Reformation and the Enlightenment, though, the field of inquiry was completely different than it would be afterward. There was only one religious establishment during that time period, and that establishment had the power of eternal fear over everyone and everything. The fact that the Roman Catholic Church had the power to ban someone not just from church but from any chance of salvation radically altered the calculus of anyone interested in pursuing any sort of intellectual endeavor. Remember, this is the same institution that sought to excommunicate Galileo and Copernicus because of their claims that the ...
