Igneous Essay Example | Topics and Well Written Essays - 1000 words

Igneous - Essay Example Igneous rocks are made when molten rock material called magma cools and solidifies. Magma may be thought of as a molten rock but it is not regularly a simple molten fluid. Nonetheless, it is rather a multifaceted blend of molten solid materials, for example, crystals, rocks, as well as dissolved vapor. Magma’s chemical composition and physical properties such as viscosity and density are all important factors that control magma’s overall behavior, for instance, how fast or slow it will move, how explosive it will be, what minerals will form in it, and their grain sizes and physical interrelationships. In terms of chemical composition, all magmas except rare carbonites are rich in carbonate component. They are also silicate magmas in which the dominant component is silica (SiO2), which generally comprises 45 % or more by weight. Alumina (Al2O3), with its abundance in common igneous rocks anywhere between 13 and 18 %, is at a distant second. Igneous rocks are categorized according to location, chemical composition, surface consistency, and mineralogy. Two significant factors used for the taxonomy of igneous rocks are the rock grain size, which largely depends on the cooling history, determines the texture and the mineral or chemical composition of the rock (Krebs, 2003 p. 95). The identification of these rocks is majorly done by texture. The grain consistency of volcanic rocks comprising the size, distribution of mineral grains, shape, orientation, and the intergranular relationships will decide if the rock is designated as simple or pyroclastic lava, or a tuff. Subsequently, it also determines what minerals are found in what kind of igneous rock. These are large rocks with mineral grains that are big enough to be identified by the eye. They are formed when magma slowly cools to form intrusive mafic igneous rocks. The well

Do governments exploit its people Essay Example | Topics and Well Written Essays - 750 words

Do governments exploit its people - Essay Example The third point that will be scrutinized in the essay is how governments exploit her people in cheap labor. Lastly, government use human weakness behavior to exploit her people, thus accepting the existence of certain companies in the country. These companies produce addictive products, some of which are not healthy to the human body. It is always seen as though the employers somehow exploits their workers by not paying them more profits, while in the reality, after a worker looks at his pay check , he will realize the real exploiter is the government. The government takes several forms of taxes before the paycheck even reaches the worker, resulting to net loss. Citizens are nothing more than serfs are under the current taxation system, serving government and those in power (Floyd 16). Over-taxation denies the ability of a worker to decide how best he can use his salary earned. People are therefore, unable to meet their basic needs with the low NET salary. Although the government imposes high taxes on its people they still end up paying more to receive public services e.g. in hospitals and schools. Tax avoidance by huge firms, organization and political leaders undermines the faith of the public in the government. All these injustices and unfairness in taxation by governments erodes the social values that abide t he societies together (Floyd 27). Nevertheless, these taxes are being invested in lobby groups and political investments. Pluralistic ignorance has been used by the government to influence the minority group’s behavior and beliefs to that of the majority to its own benefit (Jens 12). It results people supporting something that they really do not like. Citizens believe other’s supports reflect their true thoughts. Governments have joined in the social media like twitter and face-book making more people takes part on their discussion. The government does this to manipulate people
