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