Jacob Bocanegra 92613 6 th Introduction The earth has 4 layers Inner Core Outer Core Mantel Crust Roll your mouse over the circles to see the layers of the earth Home Inner Core The earth has 4 layers. Lithosphere. Earth’s Systems (spheres) . Lithosphere - . Earth’s crust and upper . mantle. Atmosphere - . Layers of gases surrounding . Earth . 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!!. Standard. . S6E5. Students will investigate the scientific view of how the earth’s surface is formed. . a. Compare and contrast the Earth’s crust, mantle, and core including temperature, density, and composition. . An Introduction to Ch 11&12. Regions of the Earth. The Earth is made up predominantly of two major regions:. A predominantly molten, central core. A mostly solid outer mantle and crust. Hydrosphere and Crust . The Earth is divided into three layers based on the compounds that makeup each layer. They are:. 1. Crust. 2. Mantle. 3. Core. The Crust. The Crust is the :. 1. outer most layer of the Earth.. 2. It is the thinnest layer.. Earth . &. Space. Evidence for plate tectonics. The match in shape between the east coast of South America and the west coast of Africa suggests both were once part of a single continent. There are similar patterns of rocks and similar fossils on both sides of the Atlantic - including the fossil remains of land animals that would have been unable to swim across an ocean.. 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. https://. www.youtube.com/watch?v=rQx2wLyagk4. . Essential Question:. How are layers of the Earth different from one another?. Standard:. S6E5a.

The crust is typically about . 30-40 km thick beneath continents. Our Earth is made up of rock, air, water and living organisms.. Rock = Geosphere. Air = Atmosphere. Water = . Hydrosphere. Living organisms = Biosphere. The Earth as a System. Earth is composed of rock – both solid and molten – as well as various metallic elements.. Mount Erebus. Mount Erebus. to. McMurdo Station. 36 km. Planetary . Surfaces I. Planetary Surfaces. Why look at the surface?. 1. formation history (composition). 2. past geologic activity. 3. current geologic activity. • Different types of rocks make up Earth's surface . NOW, you will learn . • About the different properties of Earth's layers . • About the plates that make up Earth's outermost layers. Plate Tectonics (Page 7).
