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