Across
- 1. – when the earths crust is pushed up from its sides
- 4. tube – a tube formed by cooling and solidifying of the lava walls while fluid lava continued to flow inside
- 5. volcano – a volcano that is not very steep but can be big with non- explosive eruptions
- 6. – the scale which measures the magnitude of earthquakes
- 9. – the south side of Pangaea
- 10. – the line which rocks break and move
- 12. material – debris thrown from volcanos with viscous magma
- 16. – largest type of crust
- 19. – a form of closed lava tube (with a bulbous end) that forms when lava flows into water (e.g. a lake) and cools very rapidly
- 26. – the super continent
- 28. waves – the fastest travel waves with the greatest velocity
- 29. – an earthquake that occurs before a larger seismic event
- 30. waves – waves trapped near the surface, they are the slowest and most destructive
- 33. – occurs on the tectonic plate boundaries
- 34. – lava that is parcially cooled, low viscosity, thin (like water)
- 35. – plates pushing together
- 37. – plates pulling away from each other
- 39. cone volcano – a volcano small in size with steep slopes, moderately explosive with shot eruptions
Down
- 2. – smallest type of crust
- 3. – the earths thickest layer
- 7. – plates sliding against each other
- 8. – lava with a high viscosity, blocky and rough
- 11. – semi rigid part of the mantle
- 13. vent – A point source of the Earth's surface through which lavas, pyroclastics, and gas are erupted.
- 14. – the earths thinnest layer
- 15. - the largest recorded shock
- 17. volcano – most common type of volcano, explosive eruptions and lava flow
- 18. – areas of the earths surface through which magma and volcanic gases pass
- 20. core – what layer of the earth is solid due to tremendous pressure
- 21. – the north side of Pangaea
- 22. – an earthquake that occurs after a larger seismic event
- 23. – the area on the ground directly above where an earthquake occurs
- 24. core – what layer of the earth is liquid state due to extremely high temperatures
- 25. – occurs in the middle of the plate tectonics
- 27. - hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
- 30. waves – waves that travel along the worlds outer layers
- 31. – all material ejected from a volcano
- 32. – the spot underground where rock breaks causing an earthquake
- 36. – scientist behind the theory of the continental drift
- 38. vent - an opening in the side of a volcano through which volcanic materials (like lava, gases, and pyroclastic debris) erupt.
