Plate Boundaries
Across
- 2. the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
- 6. of Plate Tectonics A theory stating that Earth's lithosphere is broken into huge plates that change in size over time and move due to convection currents in the mantle
- 7. the relatively thick part of the earth's crust that forms the large landmasses; generally older and more complex than the oceanic crust.
- 8. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate
- 10. Drift the gradual movement of the continents across the earth's surface through geological time
- 11. the thinner, younger, and more dense portion of Earth's crust that is below the oceans
- 12. The boundary between two tectonic plates that are moving away from each other in Different Directions
Down
- 1. the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to movement and convection currents occur causing the shifting of the lithosphere
- 3. large, ancient landmass that was composed of all the continents joined together
- 4. The boundary between tectonic plates that are sliding past each other horizontally
- 5. A tectonic plate boundary where two plates Collide, Come together, or Crash into each other.
- 9. breaks in Earth's crust where rocks have slipped past each other.
