Across
- 4. Boundary A tectonic where two plates are moving toward each other
- 5. Dating method of dating rocks and minerals using radioactive isotopes.
- 8. Tectonics a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.
- 10. The semi-solid layer that takes up the most space in the earth
- 11. Waves an elastic wave in the earth produced by an earthquake or other means.
- 12. Current a natural process of heat transfer involving the movement of energy and heat from one place to another
- 14. Isotope More stable version of parent isotope
- 15. Boundary a linear feature that exists between two tectonic plates that are moving away from each other
- 16. The rigid outer part of the earth, consisting of the crust and upper mantle
- 18. a neutrino or antineutrino emitted in decay of radionuclide naturally occurring in the Earth.
- 19. Core The most solid layer of the earth that is in the middle
Down
- 1. Core Above the Earth's solid inner core and below its mantle
- 2. layer of the atmosphere in which the gasses are all mixed up rather than being layered by their mass.
- 3. Isotope the isotope that decays, forming the daughter isotope after releasing a decay particle
- 6. 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.
- 7. Decay The emission of energy in the form of ionizing radiation.
- 9. pieces from a meteor that survived it’s passage through the Earth’s atmosphere
- 12. Crust The geological layer that makes up the continents and their surrounding shallow seabed or continental shelves.
- 13. Boundary the changing of energy from one type to another,
- 17. Crust The outermost layer of Earth's lithosphere that is found under the oceans and formed at spreading centers on oceanic ridges, which occur at divergent plate boundaries.
