There are three main layers on the Earth. The first is, the crust, the outer layer of Earth. It’s everywhere, on dry land and the ocean floor, however it’s

The data amassed by the scientist revealed that the Mid- Atlantic Ridge and the East Pacific Rise and countless other locations on the ocean floors display the same arrangements of varying magnetic stripes. As new volcanic rock erupts through fractures on the floor of the ocean, a progression identified as seafloor spreading, which causes the seafloor to widen (Trefil & Hazen, 2010). This new rock will be pushed aside as the continents are moved apart and as more magma comes up to take its place. The iron ore in this latest rock will steer to the position of the magnetic north pole once they get through to the top. Every occasion, that the planet’s magnetic field moves in the opposing direction, the dipole course of the planets magnetic field adjust and becomes encased in the recently constructed rock (Trefil & Hazen, 2010).

Consequently, he knew that he would need to defend his ice age theory, so he established a glacier observatory where people could visit and experience firsthand the effects that

He wanted his students to look deeper into the fish. He wanted them to find the most conspicuous features of the fish. Sure, he could of just told them, they were wrong, but that would not teach them the true meaning of observing.

The youngest oceanic crust is located along the mid-ocean ridges where new crust is formed when the old crust is pushed away from mid – ocean ridges as a result of the seafloor spreading.

"during the ten to twenty minutes they sat on the rock, a particular kind of contentment, unlike any other he knew. He did not know what this was, in words or ideas, or what the reason was; it was simply all that he saw and felt. It was, mainly, knowing that his father, too, felt a particular kind of contentment, here, unlike any other, and that their kinds of contentment were much alike, and depended on each other" (26).

Some rock’s in the Earth’s interior that are solid, are so hot that, if the pressure on these were released, or they are convected into a lower pressure zone, they could begin to melt

As he walked past the water he saw what was left of what was once his domain, a ruined memory of what he considered his golden age. Abandoned towers, broken pipes, and beanstalks grown up to great heights, leftovers of a world that he knew and loved, over and gone what once was golden and bronze. Afterthoughts of what was now gone leave him depressed, leaving him angry and sad, something which he would surely lose sleep over. Yet somehow he knew he had it good now, his life wasn't over and gone in a pile. Walking past the shores and the dock on the water, he looked past the bricks, the blocks in a pile. He noticed great items, thrown in the water, fungus and ferns and tossed about the area. These items he once used, he would swallow them whole,

Metal grated against metal, emitting a loud screeching noise as the world around him lurched upward. Already on the ground, he attempted to stand up, only to fall down, and a sharp pain shot through his hands and knees. Again, sticking out a hand and leaning against the metal wall next to him for support, he tried to stand, but all attempts proved futile as he fell a second time on his hands and knees. He sat up against the wall, pulling his legs up tight against his chest and screamed for help as the world shook around him.

Then Jerry looks up and sees that the source of light is not the end of the tunnel, but only a crack in the rock. Hopeful terms are used to describe the break in the stone. “Sunlight,” typically associated with warmth, life, and comfort, falls through it, illuminating the “clean” rock of the tunnel, and as Jerry gazes he sees a single mussel shell, the only sign on life in the tunnel. Ahead of him is “darkness,” but that is his only way out, although he thinks he has reached “the end of what he could

The Crust is solid silicate rock. It's mostly made of basalt. The motion of the lithospheric plates give rise to earthquakes and volcanism on the surface of the Crust.” “Wow you really know a lot about the Crust” said Dr. Phil. “I sure do” said Crusty.”Where are you going next?” asked crusty. “To the Mantle” said Dr. Phil. “Oh you'll meet monica the dragon!” said crusty. “DRAGON!” Dr. Phil said. “Will you come with me to introduce me to her so I don't get eaten” asked Dr Phil. “Sure I have a lot of spare time on my hands” said Crusty. Then Dr. Phil and Crusty set off to the mantle.

A swill of color at the end of the little cave. He stopped hacking to look at it. It was a sphere, floating just about eleven inches above the ground. A voice came into his head, uninvited. ‘Come, Come..’ whispered a mystical voice in his head.

1. One of the paramount topics we have covered in this course is oceanography (no surprises there). Rather than thinking of oceanography as “just” the study of the ocean, I have always viewed oceanography as the study of marine biology, marine chemistry, marine geology and marine physics. Before diving into any sort of detail, one can see (from the above) that oceanography incorporates four fundamental sciences into one topic; therefore, when asked to list three ways in which marine geology and marine chemistry interrelate, the possibilities are endless. Because we are to list just three examples, I am going to focus my answer on the Earth’s composition/layers. The first way these two fields interrelate is though convection currents (mantle). Density and temperature are two topics central to chemistry. Because density and temperature, along with depth, play a critical role in plate movement (geology), the plate tectonic theory is one example. The second way is through radioactive decay. Specifically, we use radioactive dating (e.g., isotope dating and half-lives) to determine the exact age of a specific geological structures. The third way these two fields interrelate is in determining the composition of the Earth’s inner core. I saved this example for last because it shows how marine physics can also be interrelated in marine chemistry and marine geology. We [scientific community] have a sound understanding of the Earth’s composition because of mass, density and temperature

Earth is in fact an intricate planet that has multiple layers of differing compositions. To be exact the earth has four main layers. The uppermost layer is the one humans come in most contact with, the crust. The crust consists of “thin silicate rock material”(Structure of the). Although the crust is not entirely the same. Actually there are two distinct types of crust, oceanic and continental. “The continental crust is made up of mostly rocks similar to granite while the oceanic crust is much denser and made up of a material similar to basalt”(Structure of the, Rose). The second layer is called the mantle. “The mantle is much denser than the crust and contains similar to the crust mostly solid silicate crust”(Structure of the). “As we travel further down the earth we wind up in the outer core. The outer core is a core of molten nickel and iron. Finally there’s the inner core. The inner is a solid metal core made up of nickel and iron”(Structure of the). All these layers functioning together cast out a magnetic
