One Other Category Of Tectonic Earthquake
889 wordsEarthquakes are vibrations produced in the earth's outer layer, or crust, when forces pushing on a mass of rock overcome the friction holding the rock in place and blocks of rock slip against each other. The vibrations can range from barely noticeable to very destructive. There are six types of shock waves. Two are classified as body waves which means they travel through the earth's interior and the other four are surface waves. The waves are changed by the rock types or formations they hit. Pri...
Ocean Floor Moves
1,071 wordsThe 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...
Theory Of Plate Tectonics
1,533 wordsFor 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. ...
Convergent Plate Boundary
492 wordsLab Report The structure of the earth is made up of many layers, but the crust and the upper mantle make up the lithosphere. The lithosphere is divided into individual sections called plates. The rest of the mantle makes up the asthenosphere. Convection in asthenosphere causes the plates to shift and move about. We can tell where the plates are or have been because volcanoes and earthquakes have their own boundaries when the are active. Tectonic plates have three relationships with each other. T...
San Andreas Fault Zone
490 wordsIntroduction The San Andreas Fault is a geologic fault zone between two tectonic plates that runs from San Francisco south to San Diego in California. It is an area of frequent earthquakes caused by the plates sliding past each other. It is so called because it runs along the San Andreas Valley. The San Andreas fault was brought dramatically to world attention in 1906 when sudden displacement along the fault produced the great San Francisco earthquake and fire. This earthquake was but one of man...
Life Effects Plate Tectonics From The Argument
1,493 wordsIntroduction Continental drift is the theory that the positions of the earth's continents have moved considerable distances throughout geologic time. A German meteorologist, by the name of Alfred Wegener, proposed the first comprehensive theory of continental drift in 1912. He based it on the way the continents fit together on the opposing Atlantic coasts as well as the paleontology correlation on both sides of the Atlantic. The theory he proposed, stated that, 200 million years ago there was on...
One Plate Of Ocean Crust
5,905 wordsIn 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...
Two Oceanic Plates
282 wordstwo oceanic plates were colliding into each other. Consequently, forming new oceanic crust along with over tremendous distances?" A noted English geophysicist, Harold Jeffreys, argued that it was physically impossible for masses of solid rock to move without breaking up. Plus, the driving forces from the ridges. Collision of two plates causes some crust to be destroyed or diminished in size. The results are different depending on the type of plates e movement of the Earth. Enormous blocks of sol...
Plate Tectonics Like The Earth
1,230 wordsPlate tectonics carries continents thousands of kilometers across the Earth. It creates and consumes oceans, and recycles chemicals that would otherwise build up and suffocate life. Why it is still going however is unknown. This machinery should have, by rights, seized up by now. Without this form of stress release, the tectonic plates should have long ago jammed together in a global gridlock. The process doesn't happen on any other planet-even Venus, our twin planet. So what keep the Earth movi...
