Unit 6 plate Tectonics
Across
- 3. Changes in this property is why seismic waves change direction when traveling through the layers of the Geosphere
- 5. The outer core is in this state of matter
- 7. This layer of crust is denser and more likely to
- 8. The layer in the Earth's crust where seismic waves change direction
- 9. The Earth's geosphere consists of this many layers
- 10. Lowest layer of the Mantle
- 11. Upper layer of the Mantle where convection is occurs
- 12. Waves created by earthquakes; reflect off of boundaries in the earth and refract
Down
- 1. A cycle in the Mantle where magma from the bottom rises to the top, but once there it will cool down and sink back down to the bottom. This is a continuous process that drives the movement of tectonic plates
- 2. The Lithosphere, Mesosphere and Inner core all share this property
- 4. Used to provide additional evidence of how the Earth is layered, because these objects are believed to have about the same composition of Earth
- 6. Layer of the geosphere that encompasses the Crust and upper Mantle
