- 12. - the oceanic crust consists of a volcanic lava rock called?
- 13. - formed as a result of repeated flooding and evaporation.
- 16. - separates lithosphere and asthenosphere
- 18. - consist of heavy metals.
- 20. - deposited when the velocity of the transporting medium drops.
- 21. rocks - formed on the surface of the earth, either in water or on land.
- 24. - made of minerals follow exact chemical specifications and bonds.
- 26. - float on the soft, plastic mantle which is located below the crust.
- 27. rock - subjected more intense pressure or heat and as a result underwent a complete change.
- 31. metamorphism -they come in contact with a heat source(usually a magma body)
- 33. - thinnest outer most layer.
- 34. - disintegrate into smaller pieces.
- 36. Bang Theory - states that the universe began as an incredibly hot.
- 37. - a naturally occuring chemical compound.
- 38. Suess - Australian geologist who first realized that there had once been a land bridge connecting.
- 40. rocks - rocks formed by solidification of magma.
- 42. Cloud theory - captured by our sun,instead of being drawn into it, they began whirling and pushing themselves into planets and moons.
- 44. core - hot liquid iron.
- 45. - rocks which are formed from organic materials such as the calcium from the shells and bones of animals.
- 48. Wegener - German geologist and meteorologist.
Down
- 1. Igneous rock - magma cool within the earth's crust.

- 11. - The study of rocks.
- 14. - a natural science that studies of celestial object.
- 15. current - caused by the very hot material at the deepest part of the mantle rising.
- 17. Igneous rock - magma rises to the surface and erupts.
- 19. - removed from its place of origin by running water, winds and glaciers.
- 22. - Which layer is plastic?
- 23. crust - crust is less denser.
- 25. theory - our planets and moons were wondering around in space and the planets were captured by the gravity of our sun.
- 28. Collision - our world is said to have collided with a small planet.
- 29. - a basic sedimentary rock which is composed of clast on little pieces of broken-up rock.
- 30. - the continental crust is composed mostly?
- 32. crust - crust is denser.
- 35. metamorphism - formation of mountain belts.
- 39. theory - that our sun will burst one day, and all our planets came from it.
- 41. collision - our entire solar system suggests that out planets, moons, and the sun all spun off from a collision between stars.
- 43. - gigantic super continent.
- 46. hypothesis - the sun and its planets supposedly condensed out of swirling eddies of cold, dark,interstellar, clouds of gas and dust.
- 47. State Theory - the density of matter in the expanding remains unchanged due to a continuous creation of matter.
