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