Inner core Section II: Matching: Use the diagram below to fill in the appropriate part of the earth. ( Use numbers not letters) ( 1 point each) 8. Oceanic Crust__________ Continental Crust_________ Inner Core_____________ Outer Core__________ Upper Mantle__________ Lower Mantle____________ Section III: Traveling through the earth’s layers. (12 points) Scenario: This weekend I was at a garage sale and I bought a machine that would travel through the earth’s layers. So I decided to take a field trip and go to the core of the earth. But before I go, I decided to ask you about the density of the layers as you go through the earth. I also wanted to know if each one of the layers were a liquid or a solid. In an essay explain to me the density for each layer and if it is a liquid or solid. Make sure to explain in detail, meaning break up mantle into upper and lower mantle etc. Section IV: Short Answer ( 1 point each) 1. The Geosphere is the _________ part of the earth. 2. The Hydrosphere is the ______ part of the earth. 3. The Biosphere is the ________ part of the earth. 4. The Atmosphere is the _______ part of the earth. Section V: Solar Nebular Theory and Big Bang Theory Essay:(10 points)( two part question) Part A: Using the image below, explain in detail the solar nebular theory. Make sure to explain each step in the diagram. Make sure to include the following words 1. Gas 2. Dust 3. Protosun 4. Protoplanet 5. Solar System Part B: How does the solar nebular theory and the big bang theory differ?
