Across
- 4. The evidence that today's continents were once joined together
- 5. Two tectonic plates slide horizontally past one another
- 7. Plates are moving apart from each other, causing new crust to form as magma rises to fill the gap
- 13. Steep Wall, Plates that pull apart
- 14. A divergent plate boundary where tectonic plates are pulling apart, causing seafloor spreading and the creation of new oceanic crust
- 15. The way continents fit together like puzzle pieces, identical fossils found on separate continents, and the patterns of earthquakes and volcanic activity that form along plate boundaries.
Down
- 1. Man proposing the theory of continental drift
- 2. Features that Create Volcanoes and trenches
- 3. Seafloor as a moving conveyor belt originating from an underwater mountain chain where new crust is constantly being made.
- 6. Bowl-shaped depression that collects water
- 8. The "puzzle piece" fit of continents
- 9. The areas where the Earth's lithospheric plates meet
- 10. Increased earthquakes, ground swelling, and the release of more gases
- 11. Geological features like deep ocean trenches and chains of volcanoes
- 12. Where magma rises from a deep-mantle
- 14. A large, high landform that rises steeply above the surrounding area, much higher and larger than a hill
