Across
  1. 2. Core-A sphere of hot solid metal
  2. 6. Plates-Thick plates made of andesite and granite that form the Earth
  3. 7. Plate-Occurs when two plates slide past each other
  4. 10. Currents-Caused by very hot hot material at the deepest part of the mantle rising then cooling,sinking again then heating rising and repeating
  5. 14. the plates of the lithosphere float or slide a top, a thin semi-solid layer in the upper mantle
  6. 15. Plate-Occurs when two plates move away from each other
Down
  1. 1. Plate-Earth's surface is broken into large pieces that move over the asthenosphere
  2. 3. most layer of the Earth made of the crust of the solid portion of the upper mantle
  3. 4. Continent
  4. 5. Core- Liquid metal that surrounds the Inner Corenner Core-A sphere of hot solid metal
  5. 8. Plates-Thin plates that are made of baseaet that form the ocean floor and are denser that continental plates
  6. 9. thick layer that surrounds the core and is made up of hot but mostly sold material
  7. 11. Plate-Occurs when two plates move towards each other and collide
  8. 12. of Plate Tectonics-Scientific theory explaining how the pates move on Earth's surface
  9. 13. layer of solid rock that surrounds the Earths surface
