  3. 14. The thickest layer of slowly moving solid rock between the crust and core
  4. 15. The layer of gases surrounding Earth, including oxygen, carbon dioxide, nitrogen, etc.
  5. 17. Waves Vibrations caused by earthquakes that travel through Earth
  6. 19. The height of a landform above sea level
  7. 21. A natural feature of Earth’s surface
  8. 22. The central layer of Earth, mostly iron and nickel
  9. 23. Slower seismic waves that only travel through solids
  10. 27. A tool used by scientists to measure seismic waves
  11. 28. The magnetic field generated by the movement of liquid iron in Earth’s outer core
Down
  1. 1. High, steeply rising areas of land, often with peaks
  2. 2. The force that pulls objects toward the center of the Earth, forming its spherical shape
  3. 3. The measure of how compact a material is; denser materials sink, less dense materials rise
  4. 4. The rigid outermost layer of Earth, including the crust and uppermost mantle
  5. 5. All living organisms on Earth
  6. 6. Large, flat areas of land
  7. 7. The solid portion of the core, made of iron and nickel
  8. 8. Elevated flat areas that rise sharply above surrounding land
  9. 9. The thin, rocky outer layer of Earth; includes continental and oceanic crust
  10. 11. Rock or material that is melted due to high heat
  11. 13. The arrangement of physical features on Earth’s surface
  12. 14. The strong, lower part of the mantle
  13. 16. The partially melted, flowing layer of the mantle below the lithosphere
  14. 18. Solid Earth, including rocks, minerals, landforms, and interior layers
  15. 20. The difference in elevation between the highest and lowest points in an area
  16. 24. Fast-moving seismic waves that travel through solids and liquids
  17. 25. The liquid portion of the core, made of iron and nickel
  18. 26. Nebula A giant cloud of gas and dust that collapsed under gravity to form the sun and planets
