Across
- 2. The eruption of magma from the Earth's interior, often associated with tectonic plate boundaries.
- 5. An opening in the sea floor that releases heated water and minerals, typically found near tectonic plate boundaries.
- 12. The theory that continents move slowly over the Earth's surface, changing their positions over time.
- 16. A lowland region formed by the divergence of tectonic plates, often characterized by volcanic activity.
- 17. The process by which one tectonic plate is forced under another plate, often leading to volcanic activity and earthquakes.
- 18. A tectonic plate boundary where two plates move apart, often resulting in seafloor spreading.
- 20. The study of the magnetic properties of rocks to understand the historical movements of tectonic plates.
- 22. Evidence from fossils that helps to determine historical biological distribution and support theories of plate movements.
- 25. Plates Large sections of the Earth's lithosphere that move and interact with each other.
- 26. scientist that discovered sea-floor spreading
- 27. The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.
Down
- 1. An underwater mountain range formed by seafloor spreading at a divergent boundary in the Atlantic Ocean.
- 3. A location in the mantle where heat causes the melting of rock, leading to volcanic activity, independent of plate boundaries.
- 4. The geographic spread of fossils found in different locations, which can provide evidence for historical plate movements.
- 6. A series of volcanic islands formed at a convergent boundary, typically where an oceanic plate subducts under another oceanic plate.
- 7. The semi-fluid layer beneath the lithosphere where convection currents occur, allowing tectonic plates to move.
- 8. The edges where two tectonic plates meet, where geological activity such as earthquakes and volcanic eruptions often occur.
- 9. A sudden shaking of the ground caused by the movement of tectonic plates along faults.
- 10. Information about the Earth's past climate, inferred from geological records, which can support theories related to plate tectonics.
- 11. A tectonic plate boundary where two plates collide, leading to the formation of mountains, trenches, or volcanic activity.
- 13. The movement of molten rock in the mantle caused by heat from the Earth's interior, which drives plate movements.
- 14. scientist that developed the idea of continental drift
- 15. A tectonic plate boundary where two plates slide past one another, causing earthquakes.
- 19. A change in Earth’s magnetic field recorded in rocks that provides evidence for seafloor spreading
- 21. A major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic activity.
- 23. The rigid outer part of the Earth, consisting of the crust and upper mantle.
- 24. A deep, narrow depression in the ocean floor formed at convergent plate boundaries where one plate subducts beneath another.
