The Creation Of The Ocean Floor

Oceanography is the branch of science that studies the ocean and vast amount of topics. I learned the importance of this branch among science. Science has answered many questions and created many theories that goes beyond this science in specific but help to answer more question in other branch of science. Two very important theories are the Continental Drift and the plate tectonics. These theories try to solve the question about the actual position of the continents and how they got there. There are so many terms and information to learn in order to understand these two theories for example plate boundaries, Fault, oceanic floor, volcanoes and more.
Plate Boundaries A Plate Boundaries is the location where two plates meet. There are three different plate boundaries. The Divergent plate boundaries are where new crust is generated as the plates pull away from each other. The Divergent plate boundaries occurs along spreading centers where plates are moving apart and the new crust is created by magma pushing up from mantle. A good example is the Mid-Atlantic ridge. The rate of spreading along the Mid-Atlantic ridge averages 2.5 centimeters per year. Convergent Boundaries is where the crust is destroyed as one plate dives under another. The Size of the earth has not change significantly during the past 600 millions years. The earth not changing size implies that the crust must be destroyed at about the same rate as is being created. The location where sinking of a plate occurs between an oceanic and a largely continental plate or between two largely oceanic plates or between two largely continental plates. Transform Boundaries Where the crust is neither produced nor destroyed as the plates slide horizontally…...

The Creation

...THE CREATION by: James Weldon Johnson (1871-1938) ND God stepped out on space, And He looked around and said, "I'm lonely -- I'll make me a world."   And far as the eye of God could see Darkness covered everything, Blacker than a hundred midnights Down in a cypress swamp.   Then God smiled, And the light broke, And the darkness rolled up on one side, And the light stood shining on the other, And God said, "That's good!"   Then God reached out and took the light in His hands, And God rolled the light around in His hands Until He made the sun; And He set that sun a-blazing in the heavens. And the light that was left from making the sun God gathered it up in a shining ball And flung it against the darkness, Spangling the night with the moon and stars. Then down between The darkness and the light He hurled the world; And God said, "That's good!"   Then God himself stepped down -- And the sun was on His right hand, And the moon was on His left; The stars were clustered about His head, And the earth was under His feet. And God walked, and where He trod His footsteps hollowed the valleys out And bulged the mountains up.   Then He stopped and looked and saw That the earth was hot and barren. So God stepped over to the edge of the world And He spat out the seven seas; He batted His eyes, and the lightnings flashed; He clapped His hands, and the thunders rolled; And the waters above the earth came down, The cooling waters came......

Oceans

...Oceans Name of student Name of institution Oceans About seventy-one percent of the planet is covered with water bodies most of which consists of the five major oceans namely: the Pacific, the Atlantic, the Indian, the Arctic and the Antarctic. The word “sea” is sometimes wrongly for “ocean”, but “sea” represents the saline water body surrounded by land. In terms of hydrosphere, the oceans cover about ninety-seven percent of the earth’s water bodies. The ocean is so vast and one can sail for day without encountering land. Oceanographers state that exploration so far has only covered five percent of the world ocean. The world ocean is part of the carbon cycle and influences climatic and weather patterns, therefore, it is crucial for our existence. The ocean is home to about 200,000 known species, although estimates put it at over 2million species, because exploration has not covered most of the ocean’s depth yet. Year in year out, thousands of fishing fleets bring in millions of tons of fish and other sea creatures which are used for diverse purposes from food for human and livestock to making chemicals. The oceans and their beaches are also a good place to have fun. People tour beaches all around the world for a lot of interesting activities such as swimming, surfing and sailing. They also just lie and play in the beaches to enjoy the sun and the sand. ...

The Ocean

...The Ocean The ocean makes up around 70% of the Earth’s surface. It is divided into several separate oceans which interconnect bodies of salt water. The major oceans are the Pacific, Atlantic, Indian, Southern, and Artic Ocean. The ocean has many functions. It keeps the Earth’s temperature moderate by absorbing solar radiation. It is then stored as heat energy which is distributed around the globe by the ocean currents. This keeps the land and air warm during the winter and cools it down during the summer. According to MarineBio, temperature and density share an inverse relationship. As temperature increases, the density—spaces between the water molecules—decreases. On the other hand, salinity and density share a positive relationship. As density increases so does the salinity—the amount of salt in the water. Temperature will always change within the depths of the ocean because warm seawater floats and cold seawater sinks. When the temperature, density, or salinity of a layer of ocean changes rapidly, the region is known as a cline. Thermoclines are areas of rapid change in temperature, where most people swim in the ocean and are the most important. Pycnoclines are areas of rapid change in density and haloclines are areas of rapid change in salinity. Living in San Francisco, the ocean is pretty hard to ignore. Around my neighborhood tons of people head out to Ocean Beach on a hot sunny day. Watching the waves go back and forth from the shore to the ocean is......

Ocean

...Oceans are large bodies of saltwater. Life on this wonderful planet earth began in these huge bodies of water. Oceans are unique in this galaxy. No other planet on the Solar System has water on its surface. Oceans cover approximately 71 percent of our planet's surface and hold around 97 percent of the planet's water. There are five oceans and many seas on the planet. The five oceans are: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean. The Pacific Ocean is the largest and the deepest ocean in the world. It is larger than all of the planet's land areas combined. Oceans support the lives of nearly 50 percent of all species on our planet. They play a major role in shaping the earth's climate. For instance, how the monsoon fares will depend to a great extent on what happens in the Indian Ocean. Oceans play a key role in the planet's water cycle. They are the sources of water vapor, which is necessary for heat transportation in the atmosphere. Excess water in the land flows to the oceans. Oceans act as huge reservoirs of carbon and play a major role in the global carbon cycle. Oceans play a critical role in regulating our planet's temperature. They act as thermostats. They absorb carbon dioxide from the atmosphere, thereby reducing the temperature. They also emit heat absorbed by the sun, thereby increasing the temperature of the surrounding atmosphere. They keep the atmosphere warm during the winter and cool during the summer. ...

The Creation

...that God is the source of the entire natural world. From this creation, we have day and night, land and water, heaven and earth. All the stars, moons, and planets are His design. Everything we see today is a result of that creation. All these things He created for His own pleasure. God desired to populate the earth. He did this with animals and humans. This means God also created man (and woman). All was flawless in the world. There was no death, no sin. Adam and Eve had a perfect relationship with each other, and with God. He had created them in His own image. He walked and talked with them frequently. He gave Adam complete control of everything in the garden, allowing them to eat “of every tree of the garden” (Gen.2:16, NKJV) except for “the tree of knowledge and evil” (Gen. 2:17, NKJV). As long as Adam followed this one rule, he and eve were welcome in the garden. This all changed when Eve allowed herself to be tempted by Satan while Adam stood idly by. At this point, all perfection came to an end. Death, both physical and spiritual, had entered the world. Adam and Eve had disobeyed God’s one commandment. They were thrown out of Eden, and separated from God. This one act has had massive impact on the entire population of the world ever since. The next generation, and all generations that followed, wasn’t immune from sin. The story of Cain and Abel (Gen. 5, NKJV) is one of jealousy and murder. God’s once perfect creation continued to live in sin. In the subsequent chapters......

Texts from the Bible stand at the center of analysis, while accompanying textbooks help us to contexualize biblical materials within history. Each week revolves around a particular theme with one lecture on the Hebrew Bible/Old Testament and one on the New Testament. Themes include creation, birth, the hero, the mountain, the community, the Temple, suffering, and the end of time. As we place biblical texts in their historical contexts, we will consider the Bible as a literary work with distinct genres, themes and conventions. The thematic connections between the Hebrew Bible and the New Testament will be explored at the same time that differences in their style and message are investigated. While reading the Bible, we will develop a vocabulary for discussing literary texts as well as a vocabulary specific to texts from the ancient world. This lively and pluralistic course provides a thorough introduction to the literature of the Bible. Course Objectives The Bible is a central text that has influenced literature,......

Ocean

...Tides The Earth’s waters move back and forth every-day, causing currents and tides. Tides are the daily or twice daily rise and fall of the oceans. Tides are caused by the gravitational pull of the moon and sun on the ocean. The rise and fall of tides causes water to move in and out of estuaries, bays and harbors. This movement is called a tidal current. When the tide is rising, water flows from the ocean into the bay creating a flood current. When the tide falls, water flows from the bay back into the ocean creating an ebb current. The highest tides, called spring tides, are formed when the earth, sun and moon are lined up in a row. This happens every two weeks during a new moon or full moon. Smaller tides, called neap tides, are formed when the earth, sun and moon form a right angle. This causes the sun and moon to pull the water in two different directions. Neap tides happen during a quarter or three-quarter moon. I once went fishing with my dad at the beach and the tides were really low. We had to wait until the next morning to get a nice high tide to be able to catch any fish. The low tide waves were so far away that the fishing line barely went out. This is my personal connection because tides make a big impact on people who love to fish. Normally, fish like to be away from shore so if the tide is low, there wouldn’t be any fishes. My life does not depend on tides, however; but the fishes do.....

The Creation of the Ocean Floor

...The Creation of the Ocean Floor Anitreas Weeks SCI/209 January 26, 2013 Cynthia Collin-Clausen The Creation of the Ocean Floor When most individuals think about the ocean they visualize water, and the creatures of the sea. Rarely do individuals think about the sea floor or the creation process of it. Sea floor spreading and plate boundaries are not a common subject to anyone outside of a scientific or marine biology lab. The purpose of this paper is to identify plate boundaries. Compare and contrast ideas behind plate tectonics and the theory of the continental drift. There are many types of plate boundaries. Each one is unique in its own way. Below three of the primary types are described in detail. There are several natural events that occur as a direct result of plate boundary interaction. To properly understand the what and how of plate boundaries one must first know what they are. According to Annenberg Foundation (2014), “The border between two tectonic plates is called a boundary. All the tectonic plates are constantly moving — very slowly — around the planet, but in many different directions. Some are moving toward each other, some are moving apart, and some are sliding past each other” (para. 3). Divergent, convergent, and transform are the three primary types of plates. According to "Plate Tectonics" (2010) “A divergent boundary occurs......

...Executive Summary In the case of Ocean Carriers, protagonist Mary Linn must decide upon the best alternative regarding the building of a capesize carrier that a client has requested. Her choices in the matter include: 1) Building the ship and salvaging it after 15 years for a $5 million profit 2) Building the ship and keeping it in operation for its full 25 year operating life 3) Denying the request and not building the ship at all. Through my research I’ve found that the best decision for Mary Linn and Ocean Carriers would be to deny the request from the client due to steep potential losses that are likely to be incurred over the life of the ship. Problem, Opportunity, and Objectives In this case the protagonist, Mary Linn, must decide if building a new capesize carrier per request from a client will be a profitable venture for the Ocean Carriers shipping company. Opportunity/Problem | Cost | Anticipated Result | Through looking at the different approaches to this opportunity Mary Linn hopes to find a solution that will allow Ocean Carriers to generate the greatest amount of cash flow. | The cost in this situation is the amount of cash flow Ocean Carriers will receive, or not receive, depending on the approach they choose. | Mary Linn and Ocean Carriers will choose the solution that allows Ocean Carriers to make a profit. If a profit is not possible they will undoubtedly not proceed with the project. | Analysis of the Situation When making the......

...REV: APRIL 18, 2002 ERIK STAFFORD KATHLEEN LUCHS ANGELA CHAO Ocean Carriers In January 2001, Mary Linn, Vice President of Finance for Ocean Carriers, a shipping company with offices in New York and Hong Kong, was evaluating a proposed lease of a ship for a three-year period, beginning in early 2003. The customer was eager to finalize the contract to meet his own commitments and offered very attractive terms. No ship in Ocean Carrier’s current fleet met the customer’s requirements. Linn, therefore, had to decide whether Ocean Carriers should immediately commission a new capesize carrier that would be completed two years hence and could be leased to the customer. Ship Operations Ocean Carriers Inc. owned and operated capesize dry bulk carriers that mainly carried iron ore worldwide. This type of vessel ranged in size from 80,000 deadweight tons to 210,000 deadweight tons of cargo carrying capacity. Capesize carriers were too large to transit the Panama Canal and therefore had to sail around Cape Horn to travel between the Atlantic and Pacific Oceans. In January 2001, there were 553 capesizes in service in the world. Ocean Carriers’ vessels were mostly chartered on a “time charter” basis for a period such as one year, three years, or five years, although the spot charter market was used on occasion. The company that chartered the ship was called the “charterer.” The charterer paid Ocean Carriers a daily hire rate for the entire length of the contract,......

...Essay #2 Compare/Contrast ENG 099/011 Professor Ficarotta Patrick St. Fleur The Creation The creation of the world has been told in many ways and through the cultures has significant differences. The concept of creation that I’m most familiar with come from the bible, Genesis: Chapter 1-3. However during my recent studies on creation myths, I’ve learned many others. A common theory of the earth started is reflected in the bible and occurred within six days. Creation myths are beliefs and stories on the earliest beginnings of the world. Oral traditions throughout the different cultures are regarded as truth for the “creation” and served as the historical reference we know today. Common element s of creation myths begin with a birth, a supreme being, human and animals and instructions from the creator. Almost all cultures have at least if not all these elements in the creation myths but vary to some degree. Every revolving culture has developed creation myths centered on historical interpretation, factual events and cultural influence however the African Bushmen and the Egyptian’s are similar on morals however different in the creation. All creation myths consist of a supreme being of some kind or form. The being is not always represent but is importance is just as equal. The Greek and the Japanese show gods and goddesses, whereas the Aborigines had to supreme beings: Father of All Spirits and the Sun Mother.(Murtagh). The Japense also has two gods ......

...Guide for Case Analyses “Ocean Carriers” Objectives of case: The key objective is to develop an understanding of how discounted cash flow analysis can be used to make investment and corporate policy decisions. 1. Determine the value and net present value of a real assets; 2. Distinguishing between book value and market value; 3. Identifying and forecasting incremental expected cash flows, including initial and ongoing capital expenditures, investment in net working capital, and proceeds from asset sales; 4. Understanding the tax consequences of depreciation and asset sales; 5. Evaluating whether a policy of reselling or scrapping a vessel is most valuable. Guideline questions to cover in the case analysis: 1. What is the key issue addressed in this case? Or in other words, what is the major decision to be made by Ocean Carriers? 2. Do you expect daily spot hire rates to increase or decrease next year? 3. What factors drive average daily hire rates? 4. How would you characterize the long-term prospects of the capsize dry bulk industry? 5. Help Ms. Linn to make the purchase decision on the $39M capsize: should she buy it? Make two assumptions – first assume that Ocean Carriers is a U.S. firm subject to 35% taxation. Second, assume that Ocean Carriers is located in Hong Kong, where owners of Hong Kong ships are not required to pay any tax on profits made overseas and are also exempted from paying any tax on profit made on......
