Across
- 5. the thin outer layer of Earth that lies beneath the world's oceans,
- 6. form from compressed sediment or precipitated minerals,
- 7. a geological fault where two tectonic plates slide horizontally past each other, rather than moving toward or away from one another
- 9. a geological fault where two tectonic plates slide horizontally past each other, rather than moving toward or away from one another
- 12. an elastic wave in the earth produced by an earthquake or other means.
- 16. the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
- 17. long narrow ditch
- 18. the cooling of magma or lava
- 19. a mass of stone or metal that has reached the earth from outer space
- 21. is the sudden shaking of the Earth's surface caused by the rapid release of stress built up in the crust.
- 22. Intermost layer of the earth
- 23. a region where Earth's lithosphere is being pulled apart, creating fractures and faults
- 25. The process by which one tectonic plate is forced underneath another into the Earth's mantle.
- 26. the first waves to arrive at a seismograph
- 27. a tectonic plate boundary where two plates move apart from each other, causing magma to rise to the surface to create new oceanic crust
- 29. a type of wave that travels along the surface or boundary between two different mediums
Down
- 1. the layer of igneous, metamorphic, and sedimentary rocks that forms the geological continents and the areas of shallow seabed close to their shores, known as continental shelves.
- 2. the preserved remains, impressions, or traces of ancient living things, often over 10,000 years old, that provide scientists with evidence of past life and Earth's history
- 3. occurs when an atom loses one or a combination of particles.
- 4. the rigid outer part of the earth, consisting of the crust and upper mantle.
- 8. describes the processes and events related to the movement of molten rock (magma) from Earth's interior to the surface, leading to eruptions of lava, ash, gases, and creating volcanic landforms.
- 10. a thick layer of rock found inside a planet or other celestial body that lies between its crust and its core, making up the majority of its volume
- 11. heat-driven cycles that occur in the air, ocean, and mantle.
- 13. occurs when an atom loses one or a combination of particles.
- 14. the preserved remains, impressions, or traces of ancient living things, often over 10,000 years old, that provide scientists with evidence of past life and Earth's history
- 15. outermost layer of earth surface
- 20. the time elapsed since the oceanic crust was formed at mid-ocean ridges, a process determined by magnetic polarity patterns on the ocean floor
- 24. form when existing rocks are transformed by heat and pressure
- 28. a large, rigid slab of rock that forms part of Earth's outer shell, the lithosphere, which includes the crust and the uppermost mantle.
