tectonic plates (or plates which float separately and independently of the hotter mantle which sits below them) are categorized into three major categories‚ these being: Primary (Major)‚ Secondary (Minor) and Tertiary (or‚ micro-plates.) The seven major (or‚ any plates which range over at least 10 million kilometers) plates are: African plate‚ Antarctic plate‚ Eurasian plate‚ Indo-Australian plate‚ North American plate‚ Pacific plate and South American plate. These are also the primary plates which

subsides along a fault or crack. Benchmark Permanent cement or brass marker in ground indicating a measured elevation. Isostasy Condition of balance or equilibrium in Earth’s crust. Since the upper mantle acts like a very dense fluid‚ the crustal plates float on top of it. Any change in one part of the crust is offset by a corresponding change in another part of the crust. Example of Isostasy

The History of plate tectonics Before the plate tectonics revolution of the 1960’s geographers had a very basic understanding of global geological phenomena’s. while there had been many theory’s put fort that were used to try and explain these phenomena’s none had been completely successful till finally In the 1960’s The theory of plate tectonics was put forth. It was truly a unifying concept as it helps us to explain and finally understand many different aspects of geography such as the geography

Constructive Plate Boundary Definition: (Divergent boundary) - Where two plates move away from each other and new oceanic crust is formed. What is a Constructive Plate Boundary? At divergent plate margins‚ plates are moving apart and new lithosphere is being created. In the oceans‚ this has produced the mid ocean ridge system‚ which can also be described as a global range of underwater mountains. Well known ocean ridges include the Mid Atlantic Ridge‚ the East Pacific Rise‚ the Juan de Fuca

CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity) Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However‚ to us 21st centurions‚ the light bulb is nothing out of the ordinary. When computers‚ cell phones‚ laptops‚ iPods‚ etc. were invented our antennas tweaked. Now this is what you call invention! However‚ as time’s progressing we are getting used to these devices. In fact‚ charging all these appliances has become so very cumbersome. Each appliance has its

“P” plate drivers and fatal traffic accidents‚ continues to be a serious public health concern with the main age group being between 17-25 (Transport for NSW 2013a). P plate drivers are 33% more likely to have a crash than L plate drivers (Monash University 200). This is due to a number of factors such as: Inexperience Poor decision making Willingness to take risks whilst driving The influence of peer pressure Alcohol and drug use Stress and fatigue. Young drivers are constantly shown

Plate Tectonics: An Essay By: Grace Park Science 9 Mr. Achor 11-22-11 In the early 1900’s‚ scientists began to ask questions about the earth and it’s continents. Why are the same fossils found on opposite sides of the globe? Why do South America and Africa seem to fit together like two pieces of a jigsaw puzzle? Some scientists went to rather extreme measures to explain these strange phenomenons. Others took the time to come up with detailed theories

CHAPTER I THE PROBLEM AND ITS SETTING INTRODUCTION The area of wireless power transmission is very interesting. The technology is in its infancy but the overall benefits from its maturation could be significant to society as a whole. World population is expected to continue to grow exponentially. Five sixths of the world’s population lives in developing nations. Most developing nations such as China‚ India‚ and Pakistan are rapidly improving their standard of living. All of these trends point
