Across
  1. 1. The outermost layer of the Earth, which is solid and relatively thin compared to the underlying layers.
  2. 3. The eruption of magma from the Earth's interior, often associated with tectonic plate boundaries.
  3. 6. The study of the magnetic properties of rocks to understand the historical movements of tectonic plates.
  4. 9. Evidence from fossils that helps to determine historical biological distribution and support theories of plate movements.
  5. 11. An underwater mountain range formed by seafloor spreading at a divergent boundary in the Atlantic Ocean.
  6. 13. A tectonic plate boundary where two plates slide past one another, causing earthquakes.
  7. 17. forces that shape the land’s surface by building up mountains & other landmasses.
  8. 19. A natural hot spring that periodically erupts with steam and hot water, often found in volcanic regions.
  9. 20. A sudden shaking of the ground caused by the movement of tectonic plates along faults.
  10. 23. forces that destroy and wear away landmasses through process like erosion and weathering
  11. 24. Information collected from seismic waves that helps scientists understand earthquakes and plate movements.
  12. 25. A diagram that shows a vertical slice through the Earth, illustrating the layers and features related to tectonic plates.
  13. 28. scientist that discovered sea-floor spreading
  14. 30. A tectonic plate boundary where two plates move apart, often resulting in seafloor spreading.
  15. 31. Plates Large sections of the Earth's lithosphere that move and interact with each other.
  16. 32. A series of ocean waves caused by large underwater disturbances such as earthquakes or volcanic eruptions.
  17. 34. The movement of molten rock in the mantle caused by heat from the Earth's interior, which drives plate movements.
  18. 36. The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.
  19. 38. Information about the Earth's past climate, inferred from geological records, which can support theories related to plate tectonics.
Down
  1. 1. A tectonic plate boundary where two plates collide, leading to the formation of mountains, trenches, or volcanic activity.
  2. 2. An opening in the sea floor that releases heated water and minerals, typically found near tectonic plate boundaries.
  3. 4. A series of volcanic islands formed at a convergent boundary, typically where an oceanic plate subducts under another oceanic plate.
  4. 5. The semi-fluid layer beneath the lithosphere where convection currents occur, allowing tectonic plates to move.
  5. 7. The edges where two tectonic plates meet, where geological activity such as earthquakes and volcanic eruptions often occur.
  6. 8. A fracture in the Earth's crust where blocks of rock have moved past each other due to tectonic forces.
  7. 10. scientist that developed the idea of continental drift
  8. 12. The layer of the Earth located beneath the crust, composed of semi-solid rock that flows slowly.
  9. 14. The geographic spread of fossils found in different locations, which can provide evidence for historical plate movements.
  10. 15. A location in the mantle where heat causes the melting of rock, leading to volcanic activity, independent of plate boundaries.
  11. 16. A large continuous mass of land conventionally regarded as a collective region, distinct from islands.
  12. 18. The study of the structure and movement of the Earth's crust and the forces that shape it.
  13. 21. Waves of energy that travel through the Earth, generated by earthquakes or other seismic events.
  14. 22. The rigid outer part of the Earth, consisting of the crust and upper mantle.
  15. 26. The theory that continents move slowly over the Earth's surface, changing their positions over time.
  16. 27. A major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic activity.
  17. 29. The process by which one tectonic plate is forced under another plate, often leading to volcanic activity and earthquakes.
  18. 33. Molten rock located beneath the Earth's surface that can form volcanoes when it erupts.
  19. 35. A deep, narrow depression in the ocean floor formed at convergent plate boundaries where one plate subducts beneath another.
  20. 37. A lowland region formed by the divergence of tectonic plates, often characterized by volcanic activity.
