Across
- 3. a divergent boundary within an ocean plate where new oceanic crust is created.
- 6. volcanic regions created by a mantle plume coming from the mantle, then melting through the plate above. These are not near a plate boundary.
- 8. When talking about caldera formation, the average timing of major, catastrophic events
- 11. Tectonic region where two plates are moving away from each other.
- 13. energy Energy that is stored in a system. The amount of stored energy can depend on the arrangement of objects within the system.
- 14. An upward flow of hot material in the mantle. This material causes melting of the plate above.
- 15. the constant, slow movement of oceanic and continental plates on Earth’s surface. Over millions of years, plate motion has changed the positions of continents on Earth’s surface.
Down
- 1. Tectonic region where two plates are moving towards each other.
- 2. The space around a magnet where certain objects experience a non-contact force.
- 4. Areas on Earth’s surface closely associated with high thermal energy flow and/or linear patterns of volcanic and earthquake activity, like the Ring of Fire.
- 5. Thin crust beneath Earth’s big oceans (Pacific Ocean; Atlantic Ocean)
- 7. Areas on Earth’s surface with little evidence of thermal energy flow and far away from the linear patterns of volcanic and earthquake activity.
- 9. A black volcanic rock that is made from melted oceanic crust.
- 10. a light-colored volcanic rock that is made primarily of continental plate material. This type of rock is usually associated with continental caldera volcanoes
- 12. Thick crust with expanses of land (North America; South America; Asia)
