PPT-APES UNIT 1 NOTES TECTONIC PLATE MOVEMENT

CONTINENTAL DRIFT THEORY ALFRED WEGENER proposed all continents originally formed from one landmass PANGEA EVIDENCE OF CONTINENTAL DRIFT 1 Fossilized tropical plants in Greenland. Structure of the Earth. The Earth is made up of 3 main layers:. Core. Mantle. Crust. Inner core. Outer core. Mantle. Crust. The Crust. This is where we live!. The Earth’s crust is made of:. Continental Crust. Earth habitable. ? . Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.. Evolution of the Earth. Cracks in the Earth’s Crust. The . crust. , when it is solid, acts as a . heat insulator. for the hot interior of the Earth.. The molten material in the mantle, . magma. , below the crust builds up tremendous heat and pressure. . Standard . S6E5.d . Recognize that lithospheric plates constantly move and cause major geological events on the earth’s surface.. What You Will Learn. Describe the three types of tectonic plate boundaries. . Finding Euler poles. T. ransform faults. Spreading center rates. Slip vectors from earthquakes along the boundary. Geodetic measurements . . (GPS, VLBI). Euler poles. North America. Pacific. Cocos. Nazca. What to do: identify the features in the photos, make notes about landforms, describe and explain case studies . Levelled Objectives. . (What are we learning?). L1. identify tectonic landforms. L2. describe & explain landforms. Traditional Surveying uses . benchmarks . as reference points. Global Positioning uses . fixed GPS receivers . as reference points (Continuously Operating Reference System, CORS). Some images and slides from Michael Dennis, National Geodetic Survey and Lewis . (Noun). The . pieces of the Earth’s crust that float on the mantle. , causing continental drift and earthquakes and creating volcanoes, trenches, and mountains.. “The Earth’s crust is divided into . Mechanisms of Movement. Graphic . Organizer:. Write what you know about Continental. Drift & . Plate Tectonics. Continental Drift. Plate Tectonics.  .  .  .  .  .  .  .  . Lesson Objectives:. Turner – Skiff Mountain Tectonic Unit. Turner – Skiff Mountain Tectonic Unit. Turner – Skiff Mountain Tectonic Unit. Background. Walton and deWaard, basement hypothesis, 1962,. n. ow discredited.. Divergent. Convergent. Transform. Three types of plate boundary. Spreading ridges. As plates move apart new material is erupted to fill the gap. Divergent Boundaries. Iceland has a divergent plate boundary running through its middle. TECTONIC PROCESSES AND HAZARDS REVISION SUMMARY Aim: To create summary mind maps for each sub section To look at some typical A level style questions Kilauea: Earthquakes follow eruptions from Hawaii volcano (May 5 Richard Palin, University of Oxford, UK;. M. Santosh, China University of Geosciences, Beijing (CUGB). University of Adelaide, Australia. Ortelius World Map . Typvs. Orbis . Terrarvm. , 1570.. Culmination of centuries of research. Earthquakes. Earthquakes occur throughout the world but predominately on. plate boundaries. . For example the San Andreas Fault, a conservative plate margin. Furthermore, earthquakes also occur on the constructive plate boundaries of the Mid- Atlantic Ridge, although these are not as severe.
