Mauna Loa Carbon Dioxide
1,498 words... locked into the melted minerals. If volcanic rocks erupt on the earth's crust, such as the Andean volcanoes, then magma can interact with carbonate rocks such as chalk as it travels up through the mantle or lower crust, picking up carbon dioxide on the way. In subduction zones, where the ocean floor goes down into the mantle some carbonate rocks do get taken down and melted, recycling their carbon dioxide content, but this is a minor source compared with the mantle. Carbon is quite common de...

Lava Flows Earth Crust
1,090 wordsVolcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge sys...

The origin of volcanoes: Hot spots, can be found on plate boundaries or inside the plates. The hot spot is a place deep inside the Earth that begins to form molten lava from extreme heat conditions. It will quickly rise up, pushing and melting its way to the surface resulting in a volcano. Because of the constant moving of the plates, the volcano will be carried away from t...

Hydrothermal Vents Ocean Floor
1,069 wordsSome 7, 500 feet below the oceans surface lies a intriguing and bizarre world unlike any other. Large black volcanoes tower above the ocean floor spouting out poisonous black gas into freezing cold waters and blind crabs roam endlessly in pitch darkness. These intolerable conditions could only mean one thing, hydrothermal vents. These mystical giants of the deep have stumped some of the worlds greatest scientists who have only recently discovered that they may hold the potential key to some of t...

Many of the minerals that develop there could be minded safely and used by humans (Chu). In addition to these, there are many more reasons why vents are, and are potently important to humans. Introduction to Tube Worms Up until recently it was thought that nothing could ever live at hydrothermal vent sites. The vents hostile conditio...

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 ...

Evolutionary Theory Sea Creatures
919 wordsThe existence of mimic octopus is restricted to the islands of Indonesia, specifically off the coasts off Sulawesi, and Bali (3). Surprisingly, the octopus have been viewed during the daylight hours, generally residing near sand tunnels, and holes (1). The octopus enjoy these mounds because they provide a significant source of food, including small worms, fish, and crustaceans. The octopus utilizes its arms to feel for prey, and then captures the food through the use of expanded webs. However, w...

888 wordsThe Earth is often referred to as the blue planet since it is seventy-one percent oceans and marginal seas with only twenty-nine percent comprising the continents and islands. There are three principal topographic features of the planets ocean floor: continental margin, ocean basin floor and mid-ocean ridge. The continental margin is the most extensive feature of the ocean floor divided into two kinds: a. ) the active continental margins which are primarily located around the Pacific Ocean with ...

Nuclear Power Plants Thousands Of Years
1,408 wordsThe disposal of nuclear waste is quickly becoming the most important issue facing the environmental community today. Nearly twenty percent of our nation s electricity is being supplied by the approximately 100 nuclear power plants that are in everyday operation in the United States. So far, almost all of the nuclear waste created by these power plants is being housed in temporary storage facilities at each power plant. Although the total volume of nuclear waste produced in one year is small when...

Evidence To Support Continental Drift
1,020 wordsWe 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 things such...

Hydrothermal Vents Hydrogen Sulfide
580 wordsHydrothermal Vents are considered by scientists to be very unique and complex communities of organisms. The reason for this is due to the fact that unlike most other organisms, Hydrothermal Vents are not powered by the sun s energy. Most organisms on the Earth+s surface depend on plants to produce nutrients from sunlight. This process is called photosynthesis. These communities are unique in that they depend on a different food-making process other than photosynthesis. Bacteria at the vents make...

This chain of volcano's that lie along the west coast of central and south America, Japan and the Philippines, across New Zealand and into the Atlantic. Volcano's also occur in mid-ocean along the line of ocean ridges. The Mid-Atlantic Ridge is an example of ocean floor volcano's. When these volcano's erupt lava flows from the cracks building up the ocean floor. ...

Charleston S C Volcanic Eruptions
2,884 wordstrembling or Natural Disasters earthquake, trembling or shaking movement of the earths surface. Most earthquakes are minor tremors. Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks. The subterranean point of origin of an earthquake is called its focus; the point on the surface directly above the focus is the epicenter. The magnitude and intensity of an earthquake i...
