Earth is the only planet in the Solar System that has liquid water. The ocean contains ninety seven percent of the earth’s water and covers almost three quarters of the planet. There are four different oceans, the Pacific, Atlantic, Indian, and the Arctic. Tides and currents occur in all three of these oceans. Many different kinds of fish and mammals also make their homes in these oceans. All of these oceans are connected to each other in some way. Humans find oceans to be very interesting, beautiful, and exploring.
All oceans contain salt water and other minerals. The Pacific Ocean has the largest body of water in it. It spreads nearly halfway around the world. The Pacific Ocean is also the deepest ocean out of all four oceans. The Atlantic contains the second largest body of water. Next is the Indian Ocean, which is on the borderline of being a big ocean and a small ocean. Last is the Arctic Ocean, which by all means is the smallest ocean of them all, and the shallowest.
Tides are common features of the ocean. Tides occur when large bodies water rise and fall, because of the gravitational pull of the moon and the sun. Spring tides are especially strong tides; in spite of the name they have nothing to do with the season spring. They occur when the Earth, the sun, and the moon are in a line. Spring tides occur during the full moon and the new moon. Neap tides are especially weak tides. They occur when the gravitational forces of the moon and the sun are perpendicular to one another. When water moves from side to side, it is called a current. Currents move warm and cold water to different parts of the ocean.
Ocean water is often referred to as salt water. Ocean water becomes salty as water flows in rivers, it picks up small amount of mineral salts form rocks and soil of the riverbeds. This very-slightly salty water flows into the oceans. The water in the oceans only leaves by evaporating, but the salt remains dissolved in the ocean, it does not evaporate. So the remaining water gets saltier and saltier as time goes on.
Animals of the ocean are really interesting and fun to learn about. Many of the oceans fish use what is called a coral as a nursery and a home. This coral also serves as a shelter to the fish from other big creatures that may want to eat them.

- Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth.... [tags: Ecology ]

- Acidification of the Oceans Better known as the other CO2 problem; ocean acidification, is the increase in acidity of the oceans due to vast amounts of anthropogenic carbon dioxide being released into the atmosphere. An increase in the atmospheric carbon dioxide concentration is resulting in an increased the amount of carbon dioxide being dissolved into the oceans. The planet’s carbon sink currently absorbs around 1/3 of the carbon dioxide released into atmosphere, that’s 22 million tons of carbon dioxide being dissolved into our oceans every day....

- The Landlords of the Oceans Have you ever thought about the landlords of the oceans. There is a saying: "Big fish eats the smaller ones." The most powerful and deadly animals who taste the freedom of the sea world are whales. So many kinds of whales exist. One of the most interesting kinds is the bottle-nosed whale. It is no wonder why they are given this name. Their bulbous forehead and elongated snout give them a unique character. Besides these unique physical characteristics, they have other special qualities as well including their rarity and their enormous size.... [tags: Papers]

- The Atmosphere and Oceans The atmosphere is a cocktail of gases . The exact amounts of each gas vary as the amount of water vapour is variable. Name of Gas Amount in air % Nitrogen Oxygen Argon 78 21 1 The amount of carbon dioxide in the atmosphere is tiny (0.01%). The amounts of carbon dioxide and oxygen gas are balanced and stay the same. Photosynthesis in plants converts carbon dioxide into oxygen. Breathing and burning convert oxygen into carbon dioxide.... [tags: Papers]

- Water takes up a larger percentage of the surface of our Earth than does land. The earth’s oceans are vital aspects to our environment and it is necessary that we take care of them. On another note, global warming is an issue that is having effects on almost all aspects of our environment. Global warming itself means a gradual increase in the temperature of our Earth’s atmosphere over large periods of time. There is evidence that global warming has occurred in the atmosphere, however, now we are beginning to see its effects in the world’s oceans, as well.... [tags: Global Warming Climate Change]

- The Birth of Fish; The Death of Oceans Overview: Life and death are themselves opposites; then again in our oceans, life sometimes causes death. Over the past few decades, the demand for edible seafood has sky rocketed, resulting in the formation of aquacultures and overfishing. As of now, the two greatest threats to our marine resources result from overfishing and water pollution. Commercial fishing targets key fish species, resulting in an imbalance of the marine ecosystem. In response to the near elimination of these species, an industry has developed to raise these species in farm communities.... [tags: Essays Papers]

- Jamie Lee Wise’s essay examines the varying sources of electrical energy that we can draw from the oceans. In her well-organized and researched essay, Wise carefully explains the sources and then discusses both the benefits and drawbacks of each source. In the end, Wise’s paper argues that "public awareness and education concerning the benefits of renewable energy sources need to be increased," and that the oceans can be a valuable resourece "only if we take steps to preserve this natural wonder and use it responsibly." Harnessing the Energy of the Oceans Introduction The oceans cover nearly three-quarters of our planet and contain a vast reserve of resources, yet we are only beginning t...

- Oceans The ocean covers Seventy-one percent of our planets surface. Life is concentrated, however, in about four percent of it, and it is this four percent that is being polluted by the tons every day. Everyone needs to understand that the oceans are not endless, and not bottomless. They also much see that the ocean contains much marine life which are essential to our eco-system. And in order to preserve this other world of life, we must stop polluting the oceans, and begin to clean them up.... [tags: essays research papers]

- Two-thirds of our planet is covered with oceans. The Pacific, the Atlantic, the Indian, and the Artic are the world's major oceans. They were formed by a series of geological processes that continue to affect the Earth. Seven main parts, called lithospheric plates, make up the Earth's mantle layer and crust. The plates fit together millions of years ago, and are constantly moving (at a slow pace-like a fingernail grows) over a layer of squishy, soft rock called asthenosphere that lies beneath the crust....

The Ocean is one of the main attractions in human lives all around the world. Humans discovered oceans in the early 1400’s; well of course then it was just a large body of water to them. Humans used oceans to explore the world and as a mean of traveling. If it weren’t for oceans, America probably would have not been found until decades after Columbus died. Humans still explore the ocean. They also use the ocean for their own personal hobbies like surfing, diving, fishing, swimming, and for taking vacations.
Oceans play a major part in the worlds existence. Without oceans, life would be different. Oceans are at a high risk of pollution. If the ocean is continued to be polluted, thousands of animals will loose their homes, the human food source would run low, water would be scarce, and the beautiful ocean will become nothing but an dried up junk yard and oil feel.
