This is equal to 71 percent of the earths entire surface or about 361 million sq km (140 million sq mi). Its average depth is 5000 m (16, 000 ft), and its total volume is about 1, 347, 000, 000 cu km (322, 300, 000 cu mi). This includes the Atlantic, Pacific, and Indian oceans. These oceans are bordered by the continent...

A History Of Marine Science
1,095 wordsThe early history of marine science started about 11, 000 years ago. Nomads began voyaging into east and central Europe, and across the plains of central Asia. They journeyed to the shores of northeastern Asia and crossed the Bering Sea into North America and South America. Most traveled on foot except for those who were talented in raft building or navigation. Any coastal culture with these talents had big economical advantages and greater access to food or supplies. But when European explorers...

Opposite Direction Royal Society
1,980 words... 'During its flow, ' and this was the time when an effect was expected -- but here Faraday's power of lateral vision, separating, as it were, from the line of expectation, came into play -- he noticed that a feeble movement of the needle always occurred at the moment when he made contact with the battery; that the needle would afterwards return to its former position and remain quietly there unaffected by the flowing current. At the moment, however, when the circuit was interrupted the needle...

Ocean Currents Pacific Ocean
348 wordsSticking with the theme of ocean currents, (from portfolio # 2), I will reflect on Jan Kay? s Dec. 4, 2000 article titled? Warming taking food from Pacific. ? This article was retrieved from the Milwaukee Journal Sentinel. According to this article, warmer waters and changing ocean currents within the Pacific Ocean maybe causing a decline in plankton. Ocean plankton are the food source for many larger ocean creatures. According to a 50 year study, conducted by California Cooperative Fisheries In...

Rapid Expansion Blue Green
1,211 wordsUp until 1947, it was believed that the Cambrian Explosion marked the first true abundance of multicellular life. However, this was discovered to be untrue after Sir Douglas Mawson and R. C. Spring mistakenly came across numerous "fossil jellyfish" in the Ediacaran Hills while observing what was originally believed to be sandstones belonging to the lowest strata of the Cambrian. At first, these finding were dismissed as "fortuitous inorganic markings. " (AAS Biographical Memoirs. ) Several years...

Tectonic Plates Oceanic Crust
1,370 wordsThe core is divided into two parts, the solid inner core and the liquid outer core. The inner core is thought to be solid and primarily made up of iron and some nickel. The outer core is all around the inner core and is believed to be made up of liquid iron mixed with liquid nickel. The outer core is about 2890 to 5100 km. The inner core is 5100 to 6378 km. Earths mantle is mainly composed of substances high in iron and magnesium. The melting point of every substance depends on the pressure and ...

Earth Surface Day And Night
1,063 wordsClimate has profound Climate Climate Climate has profound effects on us, and the world in which we live. In turn we as humans, and many other global factors contribute to our climate. Almost everything in our lives somehow impacts or is impacted by climate. We as humans can affect everything, from the food we eat to the air we breathe, including climate. This is through the alteration of the earth? s surface and the introduction of pollutants and chemicals such as carbon dioxide into the atmosph...

Food And Shelter Coral Reefs
682 wordsCorals and Adaptations Coral reefs are among the most diverse and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions ranging from providing food and shelter to fish and invertebrates, to protecting the shore from erosion. Although many corals resemble plants, they are actually members of the animal phylum Cnidaria. Most corals are colonial, which means that each coral is made up of many individual polyps connected...

1,768 wordsThe objective Don John Purpose The objective of this lab is to introduce the Bipolar Junction Transistor (BJT). A BJT is a three terminal device composed of an emitter, base, and collector terminals. In this lab we will introduce two major types of BJT? s: npn and pnp. The first, npn, has an n-type emitter, a p-type base and a n-type collector. On the other hand the pnp has a p-type emitter, a n-type base, and a p-type collector. Also the transistor consists of two major pn junctions, the emitte...

B C D Magnetic Field
2,455 wordsElectromagnetic Induction Theory: The phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a p...

Coastal Plain Hudson River
1,539 wordsNew York s Geology The bedrock of the earth is made up of rock bodies that vary in size, shape, orientation, composition, color, and texture. These rocks makeup the bedrock, which is present everywhere. If one were to study a map of the bedrock from a vehicle point of view, they would find that patterns are made by eroded edges and surfaces of rock bodies that crop out of the state. Most rock bodies are originally tubular and horizontal. Deformations of these rock bodies occur over many years du...

3,922 wordsIt is not my intention to lay before you a life of Faraday in the ordinary accepting of the term. The duty I have to perform is to give you some notion of what he has done in the world; dwelling incidentally on the spirit in which his work was executed, and introducing such personal traits as may be necessary to the completion of your picture of the philosopher, though by no means adequate to give you a complete idea of the man. Michael Faraday was born at Newington Butts, on September 22, 1791,...

Southern United States El Nino
2,315 wordsEl Nino has been a reoccurring phenomenon for centuries. Man has only started to realize how much of the worlds weather is effected by it. The term El Nino refers to an irregular warming of the seas surface. During the last 40 years there have been 10 significant El Nino occurrences. Most affecting the coast of South America. Water temperatures increase along the coast as far as the Galapagos islands. Weak events will raise the water temperature 2 to 4 degrees Celsius and will have minor impact ...
