Across
- 5. - the layer under the lithosphere that flows and causes the movement of plate tectonics.
- 7. Has a trunk
- 8. - a place in the middle of a tectonic plate where hot magma rises from deep inside the Earth, often forming volcanoes.
- 9. Crust - the thick part of the Earth’s crust that forms the land.
- 11. - a type of plate boundary where two plates move away from each other, allowing magma to rise and create new crust.
- 12. - the process where eroded materials are dropped off in a new location.
- 13. - the supercontinent, Greek for “all the earth”.
- 14. - when magma cools, it crystallizes to form igneous rocks.
- 15. - rocks that form when heat and pressure change existing rocks.
- 19. - when rocks inside the Earth are exposed to intense heat.
- 21. - a type of plate boundary where two plates slide past each other, which can cause earthquakes.
- 25. Ridge - an underwater mountain range formed by divergent plates.
- 26. Crust - the thinner part of Earth’s crust that lies beneath the ocean.
- 28. Drift - a hypothesis developed by Alfred Wegener in 1912 that proposed that the Earth’s continents had once been joined as a single landmass that broke apart and sent the continents adrift.
- 29. Trench - a deep, narrow valley in the ocean floor where one plate is pushed under another.
- 31. - the type of weathering that breaks down rocks through a chemical reaction.
- 32. - the process of rocks breaking down from physical, biological, or chemical processes.
- 33. Flying mammal
Down
- 1. - rocks that are formed from cooling magma or lava.
- 2. - as sediments settle and build layers, the process that forms sedimentary rocks.
- 3. - the process that moves sediments to different places.
- 4. Tectonic - the crust is made up into large pieces that move slowly over time.
- 6. - The process where one tectonic plate is ford beneath another at a convergent boundary.
- 10. - a mountain or opening in the Earth’s surface where magma, ash, and gasses escape from below.
- 12. Man's best friend
- 13. Boundary - the place where two tectonic plates meet.
- 15. - melted rock beneath Earth’s surface.
- 16. - when rocks change shape due to pressure or tension in the Earth’s crust
- 17. Likes to chase mice
- 18. - a type of plate boundary where two plates move towards each other, creating mountains or volcanoes.
- 20. - the shaking of the ground caused by the movement of tectonic plates.
- 22. - the type of weathering that breaks down rocks without changing their chemical composition.
- 23. - the crust and part of the upper mantle that makes up the plate tectonics.
- 24. - the type of weathering caused by plants, animals, or other life.
- 27. - rocks that form from the compaction of sediments.
- 30. Large marsupial
