Bellwork o Put your N, D & B on a ½ sheet CSOP o Share the other half with another student o Label it “Earth’s Layers & Continental Drift B.W. #1” o Write down one  question that you believe will be on the test, NOT a question about the test o Clear everything else from your desk o Wait P & Q Earth’s Layers & Continental Drift Study Guide Fill in your: Name: _________ Date: ________ Block: _________ Key & Important Words First Row Crust Asthenosphere Continental Drift Convection Mantle Mid-Ocean Ridge Core Second Row Pangaea Plate Boundary Divergent Rift Valley Convergent Plate Tectonics Transform 1. The three main layers that make up Earth are the C_____, the M_____ and the C_____. Core Mantle Crust 2. Label the core, the mantle and the crust on the diagram below. Core Mantle Crust 3. The L__________ is made up of the C__________ and the upper part of the M__________. Lithosphere Crust Mantle 4. The hot softer part of M_______ that the L________ sits on top of is called the A________. Mantle Lithosphere Asthenosphere 5. Materials that are L_____ D_________ rise to Earth’s surface. Less Dense 6. Materials that are M_____ D_______ sink toward Earth’s center. More Dense 7. Earth’s core has two parts, the I_____ C____ and the O_____ C____. Inner Core Outer Core 8. The O_______ C______ is L_____ rock and the I____ C_____ is S_______ because of the immense amount of pressure that it is under. Outer Core Liquid Inner Core Solid 9. A C_______ C_______ occurs when hot rock in the mantle R______ toward the crust, C_____ and then F_____ in a continuous motion. Convection Current Rises Cools Falls 10. At a D________ B________ plates move A_________ from one another. Divergent Boundary Away 11. At a C________ B________ plates move T________ one another. Convergent Boundary Toward 12. At a T________ B_______ plates S_______ past one another. Tranform Boundary Scrape 13. Because stress builds up over time, E____________ tend to happen at plate boundaries.
