Across
- 3. A location where magma rises from deep within the Earth and can cause volcanic activity, often in the middle of a tectonic plate.
- 4. any of Earth’s main continuous areas of land, such as Africa, Asia, and North America
- 10. moving toward the same place
- 12. Drift: The gradual movement of continents across the Earth’s surface over geological time.
- 14. a diagram that shows what the inside of something looks like
- 17. water
- 18. activity: any of the many processes (such as eruptions and lava flows) in which gas, lava, and ash are pushed out on the surface of the Earth
- 23. the sudden pushing out of something, such as lava from a volcano
- 25. Currents: The movement of fluid in the mantle caused by the heat from the Earth's core, driving plate tectonics.
- 28. the outside or top layer of something
- 29. how often or fast something happens
- 30. boundary: the place where two plates meet
- 31. a long, deep indentation in the ocean floor formed when two plates move together
Down
- 1. hot liquid rock on the surface of Earth
- 2. a set of interacting parts forming a complex whole
- 5. A large sea wave caused by an underwater earthquake, volcanic eruption, or landslide.
- 6. moving apart in different directions
- 7. hot liquid rock below the surface of Earth
- 8. ridge: an underwater mountain range formed when two plates move apart
- 9. Spreading: The process by which new oceanic crust is formed at mid-ocean ridges and slowly moves away from the ridge.
- 11. where two of the tectonic plates slide alongside each other.
- 13. the slow pulling apart of land that is caused by plate movement
- 15. when an oceanic plate runs into a continental plate and slides beneath it
- 16. the layer of soft, solid rock underneath Earth’s plates
- 19. a feature that forms on the surface of a planet, such as a mountain, channel, or sand dune
- 20. The rigid outer layer of the Earth, including the crust and the upper mantle, which is broken into tectonic plates.
- 21. layer: Earth’s outermost layer of hard, solid rock that is underneath the soil, vegetation,
- 22. a sudden shaking of Earth’s surface
- 24. Plates: Large slabs of Earth’s lithosphere that move over the mantle.
- 26. one of the very large sections of hard, solid rock that make up Earth’s outer layer
- 27. Line: A crack in the Earth's crust, typically associated with plate boundaries.
- 28. Waves: Waves of energy that travel through the Earth as a result of an earthquake.
