Some people think earthquakes and volcanoes erupt spontaneously while mountains appear randomly. However that isn’t the case- they are caused by plate tectonics. Plate tectonics are a scientific theory that pertains to the large-scale motions of the Earth’s lithosphere (the rigid outermost shell) and formed form extreme core pressure. The concept of plate tectonics developed during the early 20th century and is the study of the mass of the earth and how the masses correlate to one another. The plates pull and push causing continental drift, which affects the earth by causing earthquakes, volcanoes and mountains. There are seven major tectonic plates, and minor plates, that are composed of Oceanic Lithosphere the hard outer shell of the Earth’s crust. Through subduction the plates are carried to the uppermost mantle. Material is lost in order to balance the formation of a new crust along margins, by the sea floor spreading. This provides the Earth’s total surface to remain the same through out. Movements of the plates occur because of the Asthenosphere, which turns over hot rock for a total of ten centimeters a year; located under the lithosphere. Within the asthenosphere are convection cells in which slowly turns over hot rock. The cooled rock then turns sideways and moves parallel to the Earth’s surface before returning back into the subduction zones and reheating. When this happens it is called a divergent plate boundary. Tectonic plates are able to move because the Earth’s Lithosphere has a low density and a higher strength than the underlying Asthenosphere. The temperature gets intense to the point where magma convection currents cause heat to rise slightly near the Earth’s crust. Fault lines, small openings in the Earth’s crust, where large pieces of crust are moving in different directions. An earthquake occurs when two tectonic plates collide and is along the transformation boundary fault lines. How strong the earthquake is, or how violently volcanoes erupt, depends…
decide how to proceed with either ordering more or lowering the price of the current merchandise. The company can use accounting information to determine where they are using more money or resources than necessary and to decide strategic business moves such as opening new plants and shutting down plants that aren’t cost efficient. Managing the overhead costs in production is also a way accounting can be helpful.…
it is usually found to be entirely inoperable. In rare instances the lesion is so localized that the involved trachea can be resected, and with mobilization the ends can be brought together. This is seldom true and one is faced with the problem of what to do after resection of the trachea.” The 1960s proved to be a decade when advance in tracheal surgery quickened . By 1990, resection rates for tracheal tumors reached 63% for squamous carcinoma, 75% for adenoid cystic carcinoma, and 90% for other…

A FAITH MOVE
Jesus and his disciples encountered a blind man as they headed to Jerusalem from Jericho. This blind man, begging on the side of the road, heard that Jesus of Nazareth and his disciples were near. With news having spread of many of Jesus’s miracles that had taken…
Move to the US was a hope of my family and specially were my parents and sibling. I could find this desire of many people from many different countries moved to this country with several reasons as: prosperity, politics, peace, persecution, economic opportunities, religious freedom, justice, education, employment, or even natural disasters. However, I believe that all really moved to this country for one major reason… LOVE. Love for their families, love for their future, love for their descendants…
India in the move
With more than 1,5 billion citizens, India represent a huge market for national and international companies. However India is still facing some difficulties that are slowing it expansion and its economic growth.
Trying to solve them is the main objective of the minister of finance Jaswant Singh that has to craft a budget to achieve the 10th five years plan, which constitutes an economic, and social growth project for 2002-2007. Among its main objectives…
Move, Eat, Learn
Throughout human history, traveling has held a different value for people of different countries and time periods. To people living in the Paleolithic time period, traveling was essential for survival. Whether it was following their prey or escaping harsh weather conditions, traveling defined the lifestyle for these nomads. During the Han Dynasty in China, people traveled along the silk road in the world's first international trade business. Fast forward some centuries to the Puritan…
nutrients. Xylem may also contain fibers, which can serve as storage and support. This vascular system is surrounded by an endodermis and a casparian strip, which help regulate the movement of water, as well as protect against toxins that could potentially move into the vascular system. Stems also support the principal photosynthetic parts, the leaves. This efficient conduction system occurs in vascular plants. In nonvascular plants, called bryophytes (e.g. mosses) there is a major limit to how tall the plant…

It was a frigid Friday night in the winter. The cold front came in after a few days of muggy and endless rains. It was a week that seemed endless, as the anticipation of what was to come Friday night was in the back of my friend, Matthew’s and my mind all week long. That Friday night was the all-known, annual Winter Bash. This was one of the most known and popular parties to attend every year. To maintain any sort of social status as a teenager…
applied, the primary piston moves, and closes its compensating port. Fluid pressure rises, and acts on the secondary piston. It moves, closing its compensating port. Pressure builds up in this circuit. Both pistons then move, and displace fluid into their separate circuits and apply the brakes.
If there is a failure in the secondary circuit, the primary system continues to operate normally, but with increased travel. If the primary circuit fails, no pressure is generated to move the secondary piston.…
