Information for Plate Tectonics
"Viewed from the distance of the moon, the astonishing thing about the Earth, catching the breath, is that it is alive. Photographs show the dry, pounded surface of the moon in the foreground, dead as an old bone. Aloft, floating free beneath the moist, gleaming membrane of bright blue sky, is the rising earth, the only exuberant thing in this part of the cosmos. If you could look long enough, you would see the swirling of the great drifts of white cloud, covering and uncovering the half-hidden masses of land. And if you had been looking for a very long, geologic time, you would have seen the continents themselves in motion, drifting apart on their crustal plates, held afloat by the fire beneath." (1) These were the words spoken by Lewis Thomas, the U.S. Physician and author.
The story of Plate Tectonics is a fascinating story of continents drifting majestically from place to place breaking apart, colliding, and grinding against each other; of terrestrial mountain ranges rising up like rumples in rugs being pushed together; of oceans opening and closing and undersea mountain chains girdling the planet like seams on a baseball; of violent earthquakes and fiery volcanoes. Plate Tectonics describes the intricate design of a complex, living planet in a state of dynamic flux. (1)
Many forces cause the shape of the Earth to change over long time. However, the largest force that changes our planet's surface is the movement of Earth's outer layer through the process of plate tectonics. This process causes mountains to push higher and oceans to grow wider. The rigid outer layer of the Earth, the lithosphere, is made up of plates that fit together like a jigsaw puzzle. These solid but lightweight ...

...to emerge recently concerns, perhaps, the greatest of all mysteries - the origins of life on earth. The predominant theory held that life had its origins in warm ponds or similar small bodies of water protected from the harsh environment of the early earth and far from the escaping heat of the deep sea-floors. But now scientists have discovered organisms that thrive in these hellish conditions and appear to have been around long before the earliest known organisms previously known. Could the hot vents at mid-ocean ridges have been the incubators of life on this planet? (1)

15. The pictures above show how the continents on Earth’s surface have changed position over a very long period of time. What explains this change? (S6E5e, f)
Thomas states that this whole notion is built on a faulty understanding of science and biology. He points out that most of the associations on this planet between living things are cooperative (5). "It takes long intimacy, long and familiar interliving, before one king of creature can cause illness in another" (6). If there was anything microscopic living on the moon, it would have a "lonely time waiting for acceptance to membership here" (6).
In 1977, a recent research by geochemists Eoghan Reeves, Jeff Seewald, and Jill McDermott at Woods Hole Oceanographic Institution (WHOI) is the first to test a fundamental assumption of this ‘metabolism first’ hypothesis. This popular view says simple reaction emerged near ancient seafloor hot springs. These reactions presumably turned a nonliving world to a living one.
When the plates mash together on a convergent boundary, they can create an earthquake. A place with a convergent boundary is New Zealand. When the plates pull apart, a divergent boundary, they create a hole in the ocean that causes molten lava to rush up and it causes a volcano to form. A place with a divergent boundary is Iceland. With about 130 volcanoes all together, it has the most volcanoes of any country in the world and is on two tectonic plates. Santorini is currently in an area of earth where the African and Eurasian plate meet, and Atlantis disappeared with a rumble that could have come from a volcano or an
Since California had previously been mentioned, it is a great place to begin explaining the complex geological impacts starting with the San Andreas Fault. The San Andreas is what geologists know as a strike-slip fault, meaning that when two pl...
College athletes should be paid! College athletes are often considered to be some of the luckiest students in the world. Most of them receiving all inclusive scholarships that cover all the costs of their education. They are also in a position to make a reputation for themselves in the sporting world preparing them for the next step. The ongoing debate whether student athletes should be paid has been going on for years. These athletes bring in millions of dollars for their respective schools and receive zero in return. Many will argue that they do receive payment, but in reality it is just not true. Costs associated with getting a college education will be discussed, information pertaining to the National Collegiate Athletic Association (NCAA), and benefits student athletes receive. First, I’ll start with costs associated with college and most of all why student athletes should be paid!
Volcanism is a major part of the Galapagos and their formation. The island chain is positioned on the Nazca Plate, which is subducting beneath the South American Plate at a geologically rapid pace of 2.5 inches per year. In addition, this Nazca Plate is located directly on top of the Galapagos Hotspot. It is here that mantle plumes melt Earth’s crust, creating volcanoes as a product. The oldest island was first shaped by this ...
Since the beginning of human kind there has been a cloud of wonder of how our planet was formed. Scientist interested in this field through out the years have developed many different theories to how our planet came about. Before the Twentieth Century, scientists and geologists thought that mountain structures were due to the massive tightening of the earth caused by the gradual cooling of molten rocks. In 1900, American scientist Joseph Le Conte, published an article in the Appleton's Popular Scientific Monthly. He described that the problem in understanding mountain building was establishing the cause of sideways pressure. It was not until 1910, that an American Geologist named F.B.Taylor, proposed the idea of a continental drift. Other scientists dismissed Taylor's idea, because there was just not enough proof. However, Taylor's idea was then backed up by a German scientist named Alfred Wegener. He proposed that the continents surrounding the Atlantic Ocean, Africa and South America fit together like a jigsaw puzzle. His broad range of studies enabled him to incorporate his theory of Plate Tectonics. Wegener, later in 1915 while in the German military published his idea that interpreted how his continental drift theory worked. He proposed that a huge landmass called Pangea, meaning ("all land") existed 200 million years ago. He furthered explained that this super continent began to drift apart very slowly throughout millions of years into what it looks like now. Wegener went on several expeditions through out his life to the continents of South America and Africa.
College athletes are undoubtedly some of the hardest working people in the world. Not only are they living the life of an average student, they also have a strenuous schedule with their specific sport. One of the most discussed topics in the world of college athletics is whether or not student-athletes should be paid money for playing sports. The people who disagree with the idea have some good arguments to make. Primarily that the athletes get to go to school for free for playing sports. Another argument is that if student-athletes were to get paid then it would ruin the amateurism of college sports. People who are against paying the athletes do not want to see the young people become focused on money. “Paying student-athletes would dramatically shift their focus away from where it should be - gaining knowledge and skills for life after college” (Lewis and Williams). This is very understandable because one of the biggest reasons college sports are so popular is because the athletes play for school pride and for bragging rights. They play because they enjoy the game, not because it is their job. Most people that disagree with the idea of paying the athletes fail to realize what really goes on behind the scenes. At most Universities around the country the bulk of the income the school receives is brought in through the athletic programs. In fact the football and basketball teams usually bring in enough money to completely pay for the rest of the athletic programs all together. To get a better understanding of how much has changed in the world of college sports a little history must be learned.
The Affordable Care Act, more commonly known as Obamacare, is a new health policy created by the American federal government. Its purpose is to make healthcare more affordable and friendly for the people. Unfortunately in some way that does not prove to be the case. It is becoming apparent that Obama may have made some misleading statements to help get the ACA put into action. The ACA is sprinkled with many flaws that call for a reform such as people’s current plans being terminated, high costs, and at minimum some people’s hours being cut by their employers.
First you might need to know definition of tectonics. It is a theory in geology. The lithosphere of the Earth is divided into a small number of plates which float on and travel independently over the mantle and much of the Earth’s seismic activity occurs at the boundaries of these plates. That is the official definition of Plate tectonics. secondly, this plate covers many parts of continents. plate boundaries don’t go according to Continents boundaries, they make their own boundaries. The North American plat...

One argument that supports the panspermia theory is the emergence of life soon after the heavy bombardment period of earth, between 4 and 3.8 billion years ago. During this period, researchers believe the Earth endured an extended and very powerful series of meteor showers. However, the earliest evidence for life on Earth suggests it was present some 3.83 billi...
Plate tectonics is the theory that landmasses on tectonic plates are in slow constant movement due to convection currents in the mantle. Plate tectonics, or the movements of plates above the lithosphere (the most upper layer of earth's crust) can cause divergent, convergent,and transform boundaries.A boundary the way two tectonic plates collide. is Continental plates are plates that the continents are formed on. Oceanic plates are plates that the ocean covers, and the oceans form on top of these plates. Convergent boundaries and divergent boundaries are ways that these oceanic and continental plates interact with each other. Landforms are formed at boundaries. The landforms formed at boundaries depends on the type of plates that collide, and
Francis Crick, co-discoverer of DNA, has said that “the origin of life appears to be almost a miracle, so many are the conditions which would have to be satisfied to get it going” (Horgan 27).2 Noted evolutionary astronomer Frederick Hoyle has described the chances of life having evolved from nonlife to be about as likely as the chances that “a tornado sweeping through a junkyard might assemble a Boeing 747 from the materials therein” (Johnson 106). Why do respected scientists doubt what textbooks teach as fact? It would appear that these scientists know something that current theories describing the origin of life fail to explain. While current theories describe scenarios in which genetic material such as RNA becomes entrapped in a protective cell membrane as a likely recipe for the formation of life, they generally do not focus on the difficulties of forming and concentrating all of these components in the first place.3 To clarify, current theories suffer from what I call the “cookbook mentality.
