Across
- 2. the lithosphere is broken into these separate sections
- 3. a dense ball of solid metal that is under extreme pressure
- 5. a boundary where two plates move apart
- 9. a boundary that forms when two plates come together
- 11. created by the movements in the liquid outer core
- 19. waves produced inside the Earth by an Earth Quake
- 24. stes that pieces of the Earth's lithosphere are in slow, constant motion driven by convection currents in the mantle
- 25. layer of solid rock that includes both dry land and the ocean floor
- 27. any trace of ancient organisms that have been preserved in rock
- 28. makes up the majority of the Ocean crust and is a dark rock with a fine texture
- 32. a deep valley that forms along a divergent boundary
- 33. the sea floor spreads apart along both sides of a mid-ocean ridge and new crust is added
Down
- 1. a device that bounces sound waves off underwater objects and records the echoes of the sound waves
- 2. results from a force pressing on an area
- 4. heat transfer by the movement of currents within a fluid
- 6. means all lands and formed the super continent in Wegener's Theory
- 7. layer of hot solid rock beneath the crust - made up of the lithosphere and athenosphere
- 8. what something is made of
- 10. breaks in the Earth's crust where the rocks have slipped past each other
- 12. place where the oceanic crust bends downward and sinks back into the mantle
- 13. scientist who studies the Earth
- 14. measuree of how much mass there is in a volume of a substance
- 15. molten layer above the Earth's outer core that contains convection currents
- 16. heat transfer with in a material or between materials that are touching - direct contact
- 17. a well-tested concept that explains a wide range of observations
- 18. theory that the continents slowly moved over the Earth's surface
- 20. an underwater mountain range where new sea floor is created
- 21. a measure of how hot or cold an object is compared to a reference point
- 22. upppermost part of the mantle - means stone - tectonic plates
- 23. layer of molten metal - nickel and iron that surrounds the inner core
- 26. the process by which the ocean floor sinks beneath a deep-ocean trench
- 29. transfer of energy through a space - no direct contact takes place
- 30. a boundary where two plates slip past each other moving in opposite directions
- 31. rock that makes up most of the Continental crust 0 light in color and has a course texture
