Plate tectonic is a scientific theory of Earth Science which basically defines the large scale motions of the atmosphere of the Earth. The Plate Tectonic theory is based on the continental drift concept The theory was first developed in the first decades of 20th century. According to the Plate Tectonic theory‚ the lithosphere breaks up into the tectonic plates. Currently‚ there are seven or eight major plates in the Earth. Generally‚ the lithospheric plates remain on the asthenosphere. All the

Running Head: Plate Tectonics Paper Plate Tectonics Paper University of Phoenix Plate Tectonics Paper Earthquakes‚ volcanoes‚ mountains and the Earth’s crust are unique yet have one common denominator; the amazing topic of plate tectonics. Plate tectonics has a place or specifically places a role in each of these natural wonders of the world. In the following‚ Team C will discuss the theory of plate tectonics and how the theory shaped the form and composition of the movement within

Assess the strength of the relationship between tectonic processes and major landforms on the earth’s surface. Tectonic processes have been responsible for the major landforms across the Earth’s surface. These processes are controlled by the convection currents rising from the Earth’s mantle. Firstly‚ one place where tectonic activity occurs is at oceanic to oceanic constructive plate boundaries. Here two plates diverge or move away from each other‚ pushed apart by huge convection currents

Plate Tectonic Assignment 1. The Juan de Fuca and Cocos plates were once part of a much larger plate called the _________ plate. 2. How long ago was this plate the dominate plate? 3. What plate(s) are the remnants of this former plate? 4. What kind of plate boundary exists between the Juan de Fuca and the North American plate? 5. What kind of plate boundary exists between the Pacific plate and the North American plate? 6. What tectonic process is ongoing between Baja California and the North

boundaries by which an oceanic plate slides slowly under a continental plate into the Earth’s mantle‚ as the result of pressure and friction. After a long period of time the overriding continental plate is lifted up creating a mountain range. This is how the Himalayas were formed. Sometimes the extreme heat and pressure exerted on the subducting oceanic plate causes an uplift of magma from the mantle which rises above the surface‚ creating a volcano. When two plates are moving they don’t always slide

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

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

A plate tectonic is defined as a solid rock mass that builds up the Earth’s surface. The plate tectonic theory is a theory that geologists use to help explain the surface processes and events. The word plate means large pieces of the earth that are always in motion‚ lithosphere plates. Tectonics means how the continents formed and move over time. This is the theory that most geologists accept as to what happened to our continents. It states that Earth is made up of two layers‚ the lithosphere

Earth: Earth’s 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

This is a very important question that haunts us every day‚ because we don’t always know when they are coming and how bad they will be. I am Donte Lindsey and I am the director of Earth Preparedness of Los Angeles. With any type of danger the first thing you need to be prepared with is knowledge. Today we will discuss the hazards
