Across
- 5. Line of evidence used to explain why mountains of similar age and structure are found on different continents.
- 7. the breakup of this super continent lead to a snowball Earth.
- 10. first supercontinent that formed about 1.8 billion years ago.
- 11. A German meteorologist that was the first to suggest the idea of continental drift
- 12. Type of crust that has an average density of 3.0 g/cm^3 and has Abyssal Planes as a feature.
- 13. the switching of the magnetic poles betweel normal polarity and reversed polarity
- 14. the next predicted supercontinent that will form in about 250 million years
- 15. Line of evidence that uses identical bands of an extinct reptile found on different continents to support continental drift.
- 16. Theory states that the Earth's continents have moved and will continue to move over a period of time across Earth's surface.
Down
- 1. Theory that states that hot magma from Earth's mantle rises up through mid-ocean ridges then cools and flows sideways to form new seafloor.
- 2. Line of evidence that uses the existence of coal deposits that would have formed due to swamp environments but are found in now cold environments.
- 3. Type of crust that has an average density of 2.7 g/cm^3 and has features like mountain ranges.
- 4. Line of evidence revolving around the idea that the coasts of some continents appear to fit together.
- 6. Vehicle used to map the ocean floor during WWII.
- 8. the last supercontinent to form and is wildly known due to it correlation with the dinosaurs.
- 9. Study of different aged rock that explained why the ocean floor is comprised of parallel bands of crust that have alternating magnetic polarity.
