Across
  1. 3. type of force that destroys and wear away landmasses through processes like erosion and weather
  2. 4. a rock that is usually a light color and has coarse grains and makes up most of the continental crust
  3. 5. a type of weathering in which the surface of a rock is scratched and physically worn away.
  4. 9. the process of moving things from one place to another.
  5. 11. All the living things on Earth. It comes from the word “Bio” which means “life.”
  6. 14. a rock made from cemented sand grains.
  7. 16. type of force that shapes the land’s surface by building up mountains and other landmasses.
  8. 19. The area subject to flooding during a given number of years according to historical trends.
  9. 21. the ability to do work
  10. 22. layer of earth that is made mostly of the metals iron and nickel, and consists of two parts
  11. 23. transfer of thermal energy between materials because of collisions between particles
  12. 25. the amount of space that matter occupies
  13. 27. this layer is formed with the crust and rigid upper mantle, and is above the asthenosphere
  14. 28. a rate of inclination; a slope
  15. 30. chemical weathering of minerals into clay.
  16. 33. All the gases surrounding the earth. It comes from the word “Atmos” which means “air.”
  17. 34. the rigid layer of the lower-mantle and extends down to Earth’s core
  18. 36. a process in which rocks are transformed and worn away by chemical reactions.
  19. 38. a hard rock made of interlocking crystals of quartz, feldspar, mica, and other minerals.
  20. 39. a dense sphere of solid metal
  21. 40. All the oceans, rivers, lakes and water on Earth. It comes from the word “Hydro” which means “water.”
  22. 41. the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
  23. 42. vibrations that travel through Earth carrying the energy released during an earthquake
  24. 43. a process of mechanical weathering in which water seeps into cracks and freezes.
Down
  1. 1. crust that lies beneath the ocean
  2. 2. transfer of thermal energy from one material to another by electromagnetic waves
  3. 6. the soft layer of the upper-mantle on which the lithosphere floats
  4. 7. Movement caused by warm fluids rising and cooler fluids sinking.
  5. 8. the amount of matter in an object
  6. 10. a rock that forms from compacted mud and silt.
  7. 12. A description of surface features of land.
  8. 13. a process in which rocks are physically worn away without changing their chemical composition.
  9. 15. layer of molten metal surrounding the inner core
  10. 16. the crust that forms the continents
  11. 17. a type of chemical weathering in which iron reacts with oxygen to produce iron oxide, or rust.
  12. 18. the layer of rock that forms Earth’s outer surface, which includes both dry land and the ocean floor
  13. 20. the measurement of how much mass of a substance is contained in a given volume
  14. 24. process of breaking down of rocks and land due to forces such as gravity, wind, water and ice
  15. 26. the layer of hot, solid material between Earth’s crust and core
  16. 29. Process in which sediment is laid down in new locations
  17. 31. All the rock, soil and sediments that makeup Earth’s land. It comes from the word “Geo” which means “Earth.”
  18. 32. dark, fine-grained rock that makes up most of the oceanic crust
  19. 35. the physical force exerted on an object
  20. 37. a process in which a solid becomes a part of a liquid to form a solution
