Science Ch. 8 Test Prep answers:
1. lava 2. deposition 3. igneous rock 4. mineral 5. rock cycle 6. sediment 7. erosion 8. magma 9. rock 10. core
11. C 12. D 13. B 14. D
15. Check page C7 to make sure you have included the layers in the correct order.
16. (example) Igneous rock is broken into smaller parts by weathering. When these pieces are small enough, they are eroded, or carried away by wind, water, or moving ice and deposited as sediment. The sediment hardens and becomes sedimentary rock.
17. (example) The builder can plant grass. shrubs, and trees. The roots of these plants will hold the soil in place.
18. (example) You will most likely find sedimentary rock. The river would carry bits of sand, rock, and once-living things and deposit them at the mouth of the lake. There, they would harden into sedimentary rock.
19. (example) It is not a god idea to build close to a fault in the Earth's crust. Earthquakes and volcanic eruptions are more likely to occur there.
20. (example) Weathering and erosion break rocks down into smaller pieces and carry them to be deposited in lower places as sediment. This sediment presses together and hardens to become sedimentary rock.
