Across
- 3. A geological area where two tectonic plates collide and one plate is forced underneath the other and sinks into the Earth's mantle
- 6. German meteorologist and geophysicist famous for proposing the theory of continental drift
- 8. A current in a fluid that results from convection.
- 9. Supercontinent that existed from the late Paleozoic to the early Mesozoic eras (around 335 to 175 million years ago)
- 10. The formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.
- 11. Pioneering Canadian geophysicist crucial to developing plate tectonics theory
- 12. A pivotal American geologist, known for proposing the theory of seafloor spreading
Down
- 1. Theory which explains that Earth's outer shell (lithosphere) is broken into large, rigid pieces called tectonic plates that slowly move
- 2. Where two tectonic plates slide horizontally past each other, grinding sideways along faults
- 4. Where two tectonic plates collide
- 5. A tectonic plate boundary where two plates move apart
- 7. The theory that Earth's continents slowly move across the planet's surface over geological time
