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

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

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

Streak Plate Isolation for Obtaining Pure Cultures Data Interpretation 1- In order to unsure that you get a pure sample. 2-pure culture: laboratory culture containing a single species of organism. A pure culture is usually derived from a mixed culture (containing many species) by methods that separate the individual cells so that‚ when they multiply‚ each will form an individually distinct colony‚ which may then be used to establish new cultures with the assurance that only one type of organism

The Eatwell plate‚ originally designed by the Food Standards Agency‚ is the current food guide used within the UK to demonstrate the government’s dietary guidelines‚ using the visual representation of a plate to advise what constitutes a healthy balance diet (refer to figure 1). The plate is segmented into five food groups to assist in demonstrating the types of foods and the proportions which should be considered for a healthy balanced diet (Public Health England‚ 2014).

Plate Tectonics Chart Amanda Wright GLG 150 February 24‚ 2013 Karen Hansen Plate Tectonics Chart 1) How does the motion of the tectonic plates affect the climate? Climate can be affected by many things. One of the biggest affects may be the motion of the tectonic plates. The Earths plates have been in motion approximately since its beginnings or shortly after‚ continuously causing climate to change. The Earth’s movement of plates as well as the apparent polar wandering can both play a role

11/20/13 Earth Space Science Plate Tectonics Theory Plate tectonics is the theory that the outer rigid layer of the earth is divided into a couple of dozen plates that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. Plate Tectonics is cause by convection currents in the mantle of the Earth. This theory was originally called continental drift. The theory of “Pangea” that is the continents were connected was Alfred Wegener. The age of the sea floor is

Plate Tectonics Plate Tectonics The theory of plate tectonics was developed in the 1960’s and states that the earth is broken into a number of shifting plates. Plate tectonics also provides geology with a comprehensive theory of how the earth’s crust moves. In this essay I will explain the different types of plate movements‚ how the plates move and how this movement affects earthquakes and volcanoes. To begin‚ there are three different types of plate movement; divergent boundaries‚ convergent
