Across
- 4. the outer part of the earth.includes the crust and upper mantle
- 5. boundary where tectonic plates slide past each other
- 7. the solid outermost layer of the earth, lying above the mantle
- 9. the lower part of earths mantle, below the asthenosphere
- 11. below the lithosphere.hotter and more fluid part of mantle
- 12. form at convergent bounderies where one plate sub ducts under another, and magma underground is pushed upward
- 13. occurs when divergent plates separate. convection currents cause less dense materiel to rise. creates new ocean floor
- 15. boundary where tectonic plates collide
Down
- 1. large pieces of lithosphere that the ocean and continents rest on
- 2. when magma flows through a crack in the middle of a tectonic plate, and not a plate boundary. Hawaiian islands were formed this way
- 3. boundary where tectonic plated divide
- 6. the innermost layer of the earth. divided into 2 parts, liquid outer and solid inner. made of iron and nickel
- 8. the layer that lies between earths crust and core. the majority of earths mass is in this layer
- 10. when a sudden release of energy in the lithosphere creates seismic waves
- 14. the supercontinent that existed before continents separated
