PPT-Chapter 6 Restless Earth: Earthquakes, Geologic Structures, and Mountain Building

What Is an Earthquake An earthquake is the vibration of Earth produced by the rapid release of energy Energy released radiates in all directions from its source the focus Energy is in the form of waves. Move it, move it !!. What are they?. Fault: a break or fracture in the crust of Earth.. Earthquakes: shaking or trembling of the earth caused by movement along a fault.. Uplift: upward movement of Earth’s crust.. How long ago were the dinosaurs here? How do we even describe geologic time anyway?. EONS. which are divided into . ERAS. ,. which are divided into. .

The Basics, pre-1960. Radius 95% of Earth, mass 82%. 92X Earth atmospheric pressure, 97% CO2. 462°C surface temp. They Shape Our Landscape. As plates move, we may feel these movements as earthquakes. If there were no plate motions, our planet would not look like home. There would be no mountains, no valleys, no plateaus . Earthquakes result from sudden motions along breaks in Earth’s crust and can affect landforms and societies.. An entire branch of Earth science, called . seismology. , is devoted to studying earthquakes.. Who was James Hutton?. In the late 1700s, James Hutton began to question some of the ideas regarding the Earth.. He found fossils and saw them as evidence of life forms that no longer exist. . Different types of fossilized creatures were found in different layers of rock.. What is the structure of the earth.. What is Continental Drift. What causes Folding. What causes Earthquakes. What causes . Volcanos. INSIDE THE EARTH. (1) CRUST. : OUTER LAYER. GROUND WE ARE STANDING ON. Organization of . Ch. 21-24. Ch. 21.1 – Describes the geologic time scale. Ch. 22 – Precambrian Earth. . Section 1: Early Earth. . Section 2: Formation of the Crust and Continents. . Section 3: Formation of the Atmosphere and Oceans. Earthquake Risk. Earthquakes are likely wherever plate movement stores energy in the rock along faults.. Geologists can determine earthquake risk by locating where faults are active and where past earthquakes have occurred.. Move it, move it !!. What are they?. Fault: a break or fracture in the crust of Earth.. Earthquakes: shaking or trembling of the earth caused by movement along a fault.. Uplift: upward movement of Earth’s crust.. WORKSHOP ON SUSTAINABLE AND DISASTER RESILIENT URBAN DEVELOPMENT By USHA BATRA, Chief Architect (WR), CPWD, Mumbai Presented by: RAJESH KUMAR, Senior Architect, CPWD, Gandhinagar 2 INTRODUCTION THE WORLD’S URBAN POPULATION IS ENCREASING RAPIDLY AND MORE THAN 90% OF THIS IS ON ACCOUNT OF DEVELOPING COUNTRIES. Creation. Flood. Crucifixion. Los Angeles sinking. Sixth seal. 58-0927 - Why Are We Not A Denomination?. When He got it all made, it was just a great big volcanic eruption. . He let them old . volcanics. An earthquake is a motion of the ground surface.. According to A.N. . Strahler. and A.H. . Strahler. ,(1976), ‘An earthquake is a vibration or oscillation of the surface of the earth caused by a transient disturbance of the elastic or gravitational equilibrium of the rocks at or beneath the earth the surface’..
