Ocean Geography 2
The Ocean is a large body of water that is saline (salty). Around 71% of earth’s surface is cover by the oceans. The Ocean is very important to plants and animals. It has also been important to human history. Much exploration has been done by water and has been used for centuries in exploration and migration. The earth is devided into five different oceans which are all connected due to ocean currents and circulates water all around earth.
The first ocean is…..
The Pacific Ocean which the world's largest ocean and measures 60,060,700 square miles. The CIA World Factbook says it covers 28% of the Earth and it equals in size to almost all the land area on Earth. The Pacific Ocean is located in the middle (between) the Southern Ocean, Asia and Australia and the Western Hemisphere. The depth is calculated to be 13,215 feet. Also it is said that its deepest point is the Challenger Deep within Mariana Trench near Japan. The Pacific Ocean...
Investigating the Geographical Processes that are Affecting the Physical and Built Coastal Environment There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth’s surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. At North Cronulla beach erosion is evident.
How did the Atlantic System affect Europe, Africa, and the Americas? (The Earth and Its Peoples, 500)
Think back to your childhood; a time where everything and anything was possible. Magic and imagination was something that was used everyday in your life. Now think about where you are in your life right now. There is no longer any magic or mystery. Neil Gaiman and Antoine De Saint-Exupry write two different novels that include multitudes of fantasy. But in the midst of all of the fantasy is the fact that children and adults think differently. Both of these novels explore the idea that children think positively while adults grow out of that stage, developing a pessimistic way of thinking from what they experience in life.
Surfers, swimmers and sunbathers use beaches for recreation. People fish off beaches for food. Since many people take their vacations at the beach, lots of beaches in tropical locations are important to their country’s economy. Entire cities, regions and countries depend on the money tourists spend while visiting the beach. Beaches are naturally very dynamic places, but people try to control them and build permanent structures, such as houses, restaurants, shops and hotels, on or near the shore. The natural erosion and deposition of beaches becomes a problem. Beaches con disappear over time, or even over night during severe storms. Beaches are areas of loose sediment (sand, gravel, cobbles) controlled by ocean processes. Most beaches have several characteristic features. First are offshore bars, which help protect beaches from erosion. Next is the foreshore, which rises from the water toward the crest of the next feature; a berm. On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. New, smaller dunes are often changing shape as the wind continues to affect them. Waves and currents move the accumulated sediment constantly creating, eroding and changing the coastlines.
The ocean is the center and foundation of this story. The ocean is also part of the scenery and the background, without the ocean, there would be no story. Not only is the ocean the center and the foundation, it is also a symbol of many things in this story. To me, the ocean in this story takes on human characteristics in that to me, it symbolizes a seducer or seductress. The ocean also becomes an escape from reality and symbolizes life itself. The ocean is important because it is what helps bring Edna into her awakening and that is good, in the sense that it helps Edna into finding herself. However, the ocean is evil in that it is responsible for Edna’s demise.
Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
In “Chapter 6 – The Sea Around Us” of Elizabeth Kolbert’s The Sixth Extinction: An Unnatural History, the author reveals the fact that the ocean is acidifying due to human activities, such as burning fossil fuels and deforestation. In this chapter, Kolbert notes that there was a lack of biodiversity near the vents at Castello Aragonese in order to present the oceans’ future possibility. One of the types of sea creatures that ocean acidification would devastate are the calcifiers, which are organisms that create shells or skeletons made of calcium carbonate (Kolbert 117-122). Credible sources of information, such as the EPA and the Smithsonian Institution, agree that ocean acidification poses a serious threat to marine calcifiers,
Since the beginning of humankind, the study of geography has captured the imagination of the people. In ancient times, geography books extolled tales of distant lands and dreamed of treasures. The ancient Greeks created the word "geography" from the roots "ge" for earth and "grapho" for "to write." These people experienced many adventures and needed a way to explain and communicate the differences between various lands. Today, researchers in the field of geography still focus on people and cultures (cultural geography), and the planet earth (physical geography).
The Earth's oceans cover approximately three-fourths of the world's surface. Less than one century ago, it would have been difficult to imagine that humans could significantly pollute these vast bodies of water. For as long as there have been human inhabitants along the coast, people have been utilizing the ocean as a dumping ground for garbage and other rubbish. Although several view the ocean as endless and thus, having plenty of room for the waste; this belief is not true. The ocean can not accommodate dumpings without being permanently damaged. Furthermore, the immense technological revolution of the last century has increased society's ability to cause greater damage to the world's oceans.
Earth has been called the blue planet and not without reason. The ocean covers about three quarters of the earth’s surface and plays a vital role in our survival. It bounty feeds millions of people daily. Its surface absorbs more than ninety five percent of the solar radiation that reaches our planet. It is integral to the water cycle and it regulates our planets climate. But none of these roles would be fulfilled without the movement of the ocean. The currents, ribbons of movement within the greater body of water, provide the means with which our ocean distributes the nutrients and energy necessary for continued life upon earth. What are these currents and why are they so essential to our survival?
There is a global shortage of drinking water. A person might wonder how this can be if seventy percent of the earth’s surface is covered by water. Most of the Earth’s water is unsuitable for human consumption. Ocean water is salt water, which makes up 97.5% of all water on the planet. Freshwater is only 3.5% of all the water on Earth.
Water is on of the most precious natural resources that exist on our planet. “It is delivered from the atmosphere in the form of rain, snow, hail, fog, and condensation and returns to the atmosphere by evaporation and transpiration” (Hannigan 1969). Although many of us love activities that have to do with water, we disregard it and pollute out rivers, lakes and oceans. Slowly but surely we are going to harm out planet till no return. Protecting and conserving nature will secure a better future. 71% of earth is covered with oceans. Sounds like a lot right? Imagine ...
Derek Walcott, acclaimed Caribbean author, writes to make sense of the legacy of deep colonial damage. Born in 1930 in the island of St. Lucia, Walcott has a melancholic relationship with Caribbean history which shapes the way he carefully composes within “The Sea is History.” Walcott’s application of Biblical allusions seeks to revise and restore Caribbean identity.
The oceanic crust is more dense, thin and simpler in structure as compared to the continental crust. It is 6-9 kilometers thick and is made up of mainly mafic rocks or sima which is rich in iron and magnesium.
