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