PPT-Structure of the Earth

November 3132015 Objectives Students can KNOW the branches of Earth Science and the structure of the Earth UNDERSTAND that the different parts of the Earths structure interact with one another. Douglas Wiens. Department of Earth & Planetary Sciences. Washington University in Saint Louis. Gung & . Romanowicz. . [2004]. Pozgay. , Wiens, et al. . [2009]. Outline . What is seismic attenuation?. Formation of the Solar System. Formation of the Solar System. Scientists claim that 4.5 billion years ago there was just a featureless cloud of . gas..mostly. hydrogen and some helium with a little carbon and iron. Do you REALLY believe?. ?. ?. . All the planets of the solar system came out of the Sun!!. Humans have been able to peep into the mantle!!. All the Interior of the Earth is in molten state!!. The Earth has only one North Pole!!. November 2012. Breaking a complex problem into parts:. System. Closed Open. a system that does not allow matter to pass through its boundaries, but may allow energy to pass through its boundaries. The BIG Idea. : Heat escaping from Earth’s internal layers constantly changes the planet’s surface. . Lesson 1: Landforms. Main Idea. Forces inside and outside Earth produce Earth’s diverse landforms.. . General Characteristics. Composition- Gases, water vapour and dust particles. Structure: Layered structure, variation with altitude, latitude and seasons; Importance and characteristics of each layer.. Layers of the Earth. 1. 2. / . 24. 3. / . 24. Plate Tectonics. Earth’s lithosphere is broken up into plates. Hot, weak asthenosphere allows for plates to move. Plates are in motion and continually changing in shape and size. The Layers of the Earth. The Earth is an oblate spheroid – the . Solid Earth. . . It is composed of a number of . different layers. as determined by deep drilling and . seismic. evidence.. The Four Basic Layers. Layers Defined by Composition. 8.4. Earth’s Layered Structure.  . Earth’s interior consists of three major zones defined by their chemical composition—the . crust, mantle,. and . core.. • Thin, rocky outer layer. Sergei . popov. Sizes and masses. 1312.3323. Radius vs. mass. 1604.07558. Results of modeling.. Old (relaxed) planets.. Colors correspond to . different fractions . of light elements.. Light elements contribution. 6th Grade 2015-2016. By: Katherine Pease. Objective: . Students will compare and contrast the different layers of the Earth to create a informative diagram.. TEK: 6.10 The student understands the structure of Earth, the rock cycle, and plate tectonics.. . General Characteristics. Composition- Gases, water vapour and dust particles. Structure: Layered structure, variation with altitude, latitude and seasons; Importance and characteristics of each layer.. Summer Academy 2018. Many of us do not think of engineering unless it is associated with an acquaintance; a relative, friend, or neighbor who is a civil engineer, electrical engineer, or an engineer in another field.. Part 1. Seismic Waves and Interior of the Earth. The behaviour of seismic waves in the different layers of the earth provides the most authentic evidence about the composition and structure of the earth. The different types of waves, generated during the occurrence of an earthquake, are generally divided into three broad categories: .
