- 35. rocks - rocks formed by solidification of magma.
- 36. - float on the soft, plastic mantle which is located below the crust.
- 37. Igneous rock - magma rises to the surface and erupts.
- 38. an indefinite mixture of naturally occuring substances, mainly minerals.
- 39. - process that occur beneath the surface of the earth.
- 43. metamorphism -they come in contact with a heat source(usually a magma body)
- 45. Bang Theory - states that the universe began as an incredibly hot.
- 46. - formed as a result of repeated flooding and evaporation.
- 47. collision - our entire solar system suggests that out planets, moons, and the sun all spun off from a collision between stars.
Down
- 1. - the oceanic crust consists of a volcanic lava rock called?
- 2. Cloud theory - captured by our sun,instead of being drawn into it, they began whirling and pushing themselves into planets and moons.
- 3. - the continental crust is composed mostly?
- 5. - removed from its place of origin by running water, winds and glaciers.
- 7. - Which layer is plastic?
- 8. State Theory - the density of matter in the expanding remains unchanged due to a continuous creation of matter.
- 9. - rocks which are formed from organic materials such as the calcium from the shells and bones of animals.
