Plate Tectonics & Marine Resources The ocean is one of the worlds greatest natural resources. It provides the Earth’s population with numerous amounts of resources that have value and others that provide pure enjoyment. Transportation is one of the major uses of the ocean‚ along with recreational activities‚ and inspiration. As for resources extracted from the ocean that provide the economy with value‚ three of the main include oil‚ minerals‚ and food. Oil or gas are the top resources extracted

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events(40) The global seismic and volcanic activity is concentrated along the margins of the earth’s plates‚ which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and

INTRODUCTION - THE EVOLUTION OF MANAGEMENT THEORY During the industrial revolution that took place in Western Europe and North America in the 18th century; various machines were built and the economy which was based on manual labor was replaced by machines. Then factories of large scale in the garment sector‚ automobile sector etc emerged rapidly and the need to increase organizational efficiency and effectiveness has guided the evolution of management theory till today. Managers‚ theorists‚ researcher

one of the most important human activities. From the time human beings began forming social organizations to accomplish aims and objectives they could not accomplish as individuals‚ managing has been essential to ensure the coordination of individual efforts. As society continuously relied on group effort‚ and as many organized groups have become large‚ the task of managers has been increasing in importance and complexity. Henceforth‚ managerial theory has become crucial in the way managers manage

Continental drift The broad shape of Australia and its distinctive landforms have been influenced over long periods by earth movements that cause the breaking and bending of the Earth’s crust. Geographers call these movements tectonic processes. The Earth’s crust is made up of many individual moving pieces called tectonic plates. There are nine large plates and about a dozen smaller ones. The larger plates contain the continents and oceans. These plates ‘float’ on the dense layer of rock below

Lewis Henry Morgan (November 21‚ 1818 – December 17‚ 1881) was a pioneering American anthropologist and social theorist who worked as a railroad lawyer. He is best known for his work on kinship and social structure‚ his theories of social evolution‚ and his ethnography of the Iroquois. Interested in what holds societies together‚ he proposed the concept that the earliest human domestic institution was the matrilineal clan‚ not the patriarchal family; the idea was accepted by most pre-historians and

ABSTRACT In this paper‚ we examine how management theory concerning appropriate management practices has evolved in modern times‚ and look at the central concerns that have guided its development. First‚ we examine the so-called classical management theories that emerged around the turn of the twentieth century. These include scientific management‚ which focuses on matching people and tasks to maximize efficiency; and administrative management‚ which focuses on identifying the principles that will

Describe Darwin’s theory of evolution by natural selection. Darwin’s theory of evolution by natural selection is a species adaptation to its environment and the environment’s impact to the species over time. Traits that benefit the survival of the species within a specific environment pass to offspring because members of the population that have the beneficial traits are more likely to survive and reproduce. In order for a change to be evolutionary it must be genetic and on a hereditary level

The Evolution of the Atomic Theory Rob Congrove B4 10/23/00 The five atomic theorys of the past two centuries represent the sudden advancement of science in modern times. Beginning with a basic theory on the behavior of atoms to the current model‚ some changes have been made‚ and some ideas are still the same. Ancient Greek philosophers believed that everything was made up of invisible particles called atmos. Since then the theory of atoms did not progress until 1803. John

of Lithosphere * Oceanic Crust * Continental Crust Oceanic Lithosphere * the outermost layer of Earth’s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges. The oceanic crust is about 6 km (4 miles) thick. It is composed of several layers‚ not including the overlying sediment. * The topmost layer‚ about 500 meters (1‚650 feet) thick‚ includes lavas made of basalt. Oceanic crust differs from continental crust in several ways: it is thinner‚ denser
