Earth
Across
- 2. An area where tectonic plates move sideways past each other
- 3. Zone of leaching of metals and nutrients occurs in some soils beneath
- 8. Igneous rock that forms when magma rises up and cools in a place underground
- 11. An area where plates move toward one another and collide
- 13. The loss of some or all of a soil’s ability to support plant growth
- 15. The proportion of soil bases to soil acids expressed as a percentage
- 16. Rock that forms when magma cools above the surface of Earth
- 23. Unwanted waste material created during mining
- 24. outermost layer of Earth including the mantle and crust
- 25. Organic matter in various stages of decomposition
- 26. Molten rock
- 30. sum of the processes that build up and break down the lithosphere
- 31. The breakdown of rocks and minerals by chemical reactions the dissolving of chemical elements from rocks or both acid precipitation
- 33. frequency and intensity of earthquakes experienced over time
- 34. any of a group of spore-producing organisms feeding on organic matter
- 35. The sudden movement of Earth’s crust caused by a release of potential energy along a geologic fault and usually causing a vibration or trembling at Earth’s surface
- 38. gravels are compressed by overlying sediments
- 39. The rock material from which the inorganic components of a soil are derived
- 42. fracture in rock caused by a movement of Earth’s crust
- 43. geologic cycle of rocks
- 45. movement of the plates
- 46. removal of strips of soil and rock to expose ore
Down
- 1. layer of Earth located in the outer part of the mantle
- 4. large expanse of rock where a fault has occurred
- 5. Zone of accumulation of metals and nutrients
- 6. Least- weathered portion of the soil profile
- 7. the chemically distinct outermost layer of the lithosphere
- 9. a crack that occurs in rock as it cools
- 10. A horizontal layer in a soil defined by distinctive physical features such as texture and color.
- 12. formed directly from magma
- 14. An area beneath the ocean where tectonic plates move away from each other
- 17. formation of new ocean crust as a result of magma pushing upward and outward from Earth’s mantle to the surface
- 18. The mechanical breakdown of rocks and minerals
- 19. theory that the lithosphere of Earth is divided into plates
- 20. exact point on the surface of Earth directly above the location where rock ruptures during an earthquake
- 21. the process of wearing or being worn by long exposure to the atmosphere
- 22. process of one crustal plate passing under another
- 26. layer of Earth above the core
- 27. vent in the surface of Earth that emits ash, gases, or molten lava
- 28. mantle causes oceanic plates to spread apart as new rock rises to the surface at spreading zones
- 29. A concentrated accumulation of minerals from which economically valuable materials can be extracted
- 32. scale that measures the largest ground movement that occurs during an earthquake
- 36. a place where molten material from Earth’s mantle reaches the lithosphere
- 37. The physical removal of rock fragments from a landscape or ecosystem
- 40. Zone of overlying organic material mixed with underlying mineral material
- 41. zone of Earth’s interior
- 44. subjected to high temperature and pressure
