Across
- 1. deep underwater canyons that the sea-floor plunges into
- 6. a form of heat transferin the form of heat waves that can be absorbed by other objects
- 8. crust that sits on the ocean floor
- 11. a form of heat transfer which ocurs when 2 objects touch
- 12. a boundry of tectonic plates where they are moving away from eachother
- 17. where pieces of earth's crust are coming apart on land
- 18. a record of an earthquake created by a seismograph after the earthquake hits
- 20. long mountain ranges that rise up from the ocean floor that add material to the seafloor from the mantle
Down
- 2. a form of heat transfer that only ocurs in gasses and liquids
- 3. the process where older seafloor sinks back into the mantle by way of a deep ocean trench
- 4. the theory that the plates are always slowly moving because of movement deeper in earth
- 5. the layer of Earth that we are on
- 7. breaks in Earths crust where the plates have moved past eachother
- 9. crust that the continents sit on/are made out of
- 10. the shaking that happens because of movement of the rock beneath Earth's surface
- 13. a boundry of tectonic plates where they try to move in oposite directon and when they move they cause earthquakes
- 14. the most recent supercontinent
- 15. a piece of the cracked shell of the crust and rests on the mantle while fitting snuggly with eachother
- 16. a boundry of tectonic plates where they come together
- 19. the tool we use to measure seismic waves
