  • Oxygen And The Hard Shelled Bacteria
    461 words
    The origin of Eukaryotic cells In the beginning of the creation of Earth volcanoes erupted all over the planet. During this period there was a time where a brief cooling period was allowed to take place. When this period took place evaporation caused a downpour of rain which flooded the ocean creating the ocean. At the time that ocean was averaged at 3,000 degrees Fahrenheit. Around this same time an asteroid so powerful hit the Earth knocking off a large chunk of it. This chunk became the moon ...
  • Ocean Floor Moves
    1,071 words
    The Living Machine We live in an extraordinary era of exploration. We are now able to reach far out into space and deep down into the ocean. We have the advantage with technology such as computers and satellites. We can now simply understand the dynamic forces that shape our Earth. Our Earth is constantly destructing and recreating. It balances through a continuous rebirth cycle. The Earth's dynamic shape can be summed up very simply-Transfer Of Energy. This "Big Idea" helps to explain many thin...
  • Fourteen Plates In The Earth's Crust
    2,865 words
    The Forever Moving Land The land below us is always in motion. Plate tectonics studies these restless effects to give us a better understanding of the Earth and its past. New molten rocks are poured out in the form of magma from the mid-ocean ridges. The rock is recycled and re-entered back into the earth in deep ocean trenches through convection current. The convection current in the mantle drives plates around either against or away from each other. These collisions give rise to earthquakes, v...
  • Problem Of Global Warming On The Oceans
    1,712 words
    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...
  • Theory Of Plate Tectonics
    1,533 words
    For millions of years, tectonic plates have been determinate of changes in the physical face of the earth, and they continue to do so today. These massive plates move underneath the surfaces of the oceans and the continents, producing earthquakes, volcanoes and uplifts. This paper will discuss the composition, movement and history of tectonic plates, the theory of plate tectonics and its history, and tectonic plates affect the surface of the earth today and will continue to do so in the future. ...
  • Water In The Oceans
    728 words
    Oceans 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 interestin...
  • Flow Of Heat From The Earths Crust
    1,104 words
    The energy released from earthquakes and forces that move crustal plates are derived from the internal heat engine. Liquid water can exist on earth because the orbit is at the proper distance from the sun. The ozone layer is important to life on earth because it shields living things from uv rays. Constant change and state of flux on earth is caused by slow moving convection currents in the mantle. The internal heat of earth is a result of heat from radioactive decay of certain elements. The mai...
  • Earth's Model Of Total Extinction
    1,108 words
    A most recent inquiry into climatic change during the ice age and it's possibility of reoccurring is the Snowball Earth Hypothesis advanced by Paul Hoffman of Harvard University. Snowball Earth Suggest that before the Ice age, continents ice free at the poles enhanced the reabsorption of carbon dioxide through erosion of silicate minerals, reducing the greenhouse effect making the earth colder until it reached a runaway point. This effect is Hoffman calls albedo, when the atmosphere becomes so c...

    Remotely Operated Vehicles An ROV is a remotely operated vehicle which is a robot that moves in response to commands given by a human operator or a computer from a distance. Rov's mainly consist of a frame, a control system, a propulsion system, a tether management system and some usually have an on board camera. ROV's have been used for the last thirty years. They have been doing tasks that divers can't, do to Economical and safety reasons. A Submersible is a piece of machinery designed to do a...
  • Valuable Role In The Observation Of Oceans
    1,301 words
    Oceanography as Viewed from Space Introduction At first thought, studying the oceans from space seems to be a bizarre idea. Space observation helps oceanographers do research with manned and unmanned space systems. The space systems can be satellites and / or space shuttles that observe various features of the ocean such as sea-surface winds, sea-surface temperatures, waves, ocean currents, frontal regions, and sea color. Technological advances have greatly improved the ability of oceanographers...
  • Hydrothermal Vents
    1,476 words
    According to the Bible, God created the first man, Adam, from the soil and the first woman, Eve, from Adams rib. These events happened in the Garden of Eden almost six thousand years ago. That is one of the many beliefs of how carbon based life forms, otherwise referred to as living organisms, came to exist on Earth. Since the beginning of mans reign on earth he has tried to explain his origins. He has used various religions and myths of being created by some higher power and he has looked towar...
  • One Plate Of Ocean Crust
    5,905 words
    In the early 1960's, the emergence of the theory of plate tectonics started a revolution in the earth sciences. Since then, scientists have verified and refined this theory, and now have a much better understanding of how our planet has been shaped by plate-tectonic processes. We now know that, directly or indirectly, plate tectonics influences nearly all geologic processes, past and present. Indeed, the notion that the entire Earth's surface is continually shifting has profoundly changed the wa...
  • Surface Ocean Water
    2,058 words
    Voc. abyssal plain-parts of ocean that are flat and 3 km to 4 km in depth. bathyscaph-another type of submersible, self-propelled, free-moving submarine equipped for deep-ocean research. bathysphere-a spherical diving vessel that was first used for deep-ocean exploration. calcareous ooze mostly calcium carbonate. Depths below 4500 m it dissolves in the cold ocean water. continental margin shallower portions of the ocean floor made up of continental crust. Continental rise sediments formed from a...
  • Tidal Force Of The Sun And Moon
    658 words
    Gravity is the key to the Earth's rising and falling tides. The combined gravitational effects of the Sun and the Moon constantly pull the world's oceans in different directions and create tidal effects. But there are several other factors that complicate this basic process. Friction, the Earth's rotation, the tilt of its axis and the gravitational pull given off by the Sun and Moon that affects Earth's atmosphere. These forces together conspire to make our planet's oceans into a battleground. T...
  • Or Comet Impact On The Asteroid
    629 words
    Asteroid, Meteor, Or Comet Impact On The Asteroid, Meteor, Or Comet Impact On The Earth! Richie Nove Per. 2 Science Regents Paper Project One Asteroid, Meteor, or Comet Impact on the Earth! An asteroid is a small or minor planets that are members of the solar system and move in elliptical orbits. Usually found between the orbits of Mars and Jupiter. A comet is relatively small, rocky, and icy. It revolves around the sun. When a comet passes close to the sun some of the ice turns to gas. This gas...
