PPT-Tectonic plate

Noun The pieces of the Earths crust that float on the mantle causing continental drift and earthquakes and creating volcanoes trenches and mountains The Earths crust is divided into . 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. 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. . One moves oil, while the other builds mountains. Which can do more work?. Supertanker . Tectonic Plate . Mass - 2 x 10. 8. kg. Velocity - 8 m/s. Mass - 3 x 10. 20. kg. Velocity - 1 x 10. -9. m/s. 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. . Volcanism is mostly focused at plate margins. Pacific Ring of Fire. This map shows the margins of the Pacific tectonic plate and surrounding region. The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”.. 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. Tectonic Theory . Jessica Wilsey. A UDL lesson plan. What is plate . tectonic theory?. Plate tectonics . is a . theory. that describes the movements of the Earth’s . lithosphere. . . The lithosphere is made of 8 major plates and many minor plates. . 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 . CONTINENTAL DRIFT THEORY. ALFRED WEGENER . proposed all continents . . originally formed from one landmass . . (PANGEA). EVIDENCE OF CONTINENTAL DRIFT:. . 1. Fossilized tropical plants in Greenland. 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.
