San Andreas Fault Tectonic Plates
480 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...

Richter Scale Indian People
539 wordsEarthquakes are one of the most devastating natural disasters on this planet. In this essay I will talk about what an earthquake is, why India regularly suffers from major earthquakes, and how the major earthquakes effect the Indian people. I will also explain some of the most devastating earthquakes in Indias history. An earthquake occurs when tension builds up in the layers of rock underneath the earths surface. The tension is so strong that the earths plates cant handle it, so they either gri...

Bureau Of Engraving And Printing
1,129 wordsPut in short, the Bureau of Engraving and Printing is where all United States paper currency and several other paper goods for the government are manufactured. Incredibly important to our capitalist society, this bureau is kept one of the most secure and, if not completely, quite secretive about its habits. We shall, over the next several hours for me, several minutes for you, go over this process, and how it came to be. The United States Bureau of Engraving and Printing was created on August 29...

Biology Lab Report Genetic Exchange In Prokaryotes
679 wordsThis lab deals with the process of genetic exchange in prokaryotes. There are three main mechanisms of genetic exchange which include transformation, transduction, and conjugation. In transformation, DNA is released from cells in the surrounding environment which is then incorporated into the recipient cells DNA. In transduction, DNA is transferred through a virus to the recipient. In conjugation, genetic exchange occurs through direct contact with another cell and the plasmid is transferred fro...

Earthquakes Volcanoes And Mountain Ranges
586 wordsVolcanoes, earthquakes and many of the great, in size, mountains (the Himalayas, Rockies, Urals, Alps, and the Appalachians) will all be marked on my map at some point in this project. Now just let me tell you some interesting facts about some of these topics. Since recorded history, 550 volcanoes have erupted on the earths surface, but even far more have erupted unobserved on the ocean floor. The enormous Himalayas and many other great mountains are known to be young Fold Mountains. Young, beca...

Mechanisms Of Genetic Exchange Transformation And Conjugation
1,530 wordsIntroduction Genetic exchange had been known to play a role in the evolution and survival of microorganisms. Genes of one bacterium can be exchanged to another through several different ways: conjugation, transformation and transduction. However, the focus of this paper is to further examine the characteristics of conjugation and transformation mechanisms. Transformation was first discovered in 1928 by Frederick Griffith while he was studying pneumococcal infection in mice. 1 In 1944, Avery, Mac...

Shield Volcanoes Plate Tectonics
1,406 wordsWhen there is a sudden breaking of rocks within the earth or an explosion, wave like energy travels through the earth and is recorded on seismographs. These are called seismic waves and they are of two types: body waves and surface waves categorized into different kinds. What we will be discussing are body waves; there are two types of body waves: primary waves (P waves) and secondary waves (S waves). Both kinds travel through the Earths interior in all directions and arrive before the surface w...

Our ancestors often thought of volcanoes as places that powerful gods chose to make their home and they werent far from the truth. Volcano is a powerful exhibition of the might possessed by natural forces and the results of awakening such forces are often devastating. Today, volcanoes are a well-explored natural occurrence and theres even a science, called volcanology, which investigates this phenome...

Light And Dark Modern Art
2,390 wordsModern Art For The Paper Store April, 1999 Introduction Its been said that Matisse was no more an abstract artist than Picasso. No abstract painter can claim descent from their work without acknowledging that fact. The worldly motif, especially the human body, and in particular the female body, was as basic to Matisse's art as it had been to Delacroix's or Titian's. His paintings vividly communicate a tension between what he called the sign and the reality it pointed to. He had learned about thi...

Chitons live only in marine habitats and are commonly found in rocky areas of the intertidal zone along the coasts of almost every sea. They are stationary and cling to their rocky surfaces. Chitons are supported by eight calcareous plates called valves. Depending on the species, these plates may be small or large, cover...

Speed Of Light General Theory Of Relativity
3,151 wordsI. Introduction 1. Theory of Black Holes Black holes are one of the least understood phenomenons in the galaxy yet the secrets contained within the black hole could revolutionize the field of physics. Black holes are formed when an enormously massive star, most likely a neutron star, collapses in on itself. This happens because when the star dies all the energy generated from the sun s fusion reaction that was formerly pushing outward suddenly stops. When the outward force stops, the sun has so ...

Plate Tectonics Ocean Basins
530 wordsPlate Tectonics is theory of global tectonics (geologic structural deformations) that has served as a master key in modern geology for understanding the structure, history, and dynamics of the earths crust. The theory is based on the observation that the earths solid crust is broken up into about a dozen semirigid plates. The boundaries of these plates are zones of tectonic activity, where earthquakes and volcanic eruptions tend to occur. Plate Tectonics also are the cause of major features that...
