Across
- 5. The scientist that discovered HOW continental plates were moving.
- 9. The process that leads to the formation of rock layers, with the newer layers on top and the older layers further down.
- 13. _________ Energy is the energy of heat, caused by particles moving.
- 15. Hess’s discovery by using sonar to map the bottom of the ocean.
- 19. Can occur at convergent and transform boundaries as plates move past each other, get stuck, and then break free.
- 20. _________ plate boundaries where two plates move towards each other
- 21. An area of the mantle that is exceptionally hot. Can cause volcanoes to form even if not near a plate boundary.
- 25. Formed at divergent boundaries (O-O) where the sea floor spreads apart.
- 29. An object that is quick to change temperature, it does not take long for thermal equilibrium to be reached.
- 31. An object that is slow to change temperature, both heat transfer and time it takes to reach equilibrium is slow.
- 33. Formed in convergent plate boundaries (C-O) where magma rises up through the crust.
- 34. Thermal heat transfer by hot air/liquid rising and cold air/liquid sinking. Ex: hot air balloons or boiling water.
- 35. Hess’s theory that the continents were moved by convection currents in the asthenosphere.
- 36. __________ evidence used to support Wegener’s hypothesis. Continents fit together like puzzle pieces.
Down
- 1. Large volcanoes that are ranked an 8 (the highest possible score) on the Volcanic Eruption Index.
- 2. The scientist who first proposed the theory that the continents used to be one landform.
- 3. __________ evidence used to support Wegener’s hypothesis. Common fossils found across several continents now separated by oceans.
- 4. What is reached with two substances exchange heat and become the same temperature.
- 6. __________ plates that have the continents on them.
- 7. Is how heat is measured.
- 8. _________ plate boundaries where two plates move away from each other
- 10. Areas that have the same patterns of the layers of sediment, indicating that they were once located in the same area.
- 11. __________ evidence used to support Wegener’s hypothesis. Ex: tropical plants once in Antarctica and signs of past glaciers in South America and Africa.
- 12. Wegener’s hypothesis that all the continents were once one super continent that then separated apart. Referred to as _______________ theory.
- 13. _________ plate boundaries where two plates move past each other in opposite directions
- 14. Formed at convergent boundaries (C-C). Also can be referred to as Fold _________.
- 16. _________ Energy is the energy of particle motion.
- 17. __________ evidence used to support Wegener’s hypothesis.Mountains end at the coastline of one continent and pick up at the coast of another continent.
- 18. The supercontinent that existed 200 million years ago.
- 22. __________ plates that are located under the ocean.
- 23. This happens when two plates collide and the denser of the two plates goes underneath the less dense plate.
- 24. Thermal heat transfer by direct contact. Ex: touching a hot stove.
- 26. Formed at convergent boundaries (O-O)
- 27. Formed when a supervolcano erupts and collapses inward to the chamber where the magma was once stored.
- 28. Thermal heat transfer by heat moving through space. Ex: the sun, standing near a fire.
- 30. Formed at divergent boundaries (O-O) where magma rises up and cools from the seawater
- 32. Formed at a convergent boundary (O-C) where the oceanic plate subducts under the continental plate.
