Across
  1. 4. A tectonic boundary between where two plates spread apart from each other
  2. 8. Thickest less dense part of earth’s crust that makes up the land.
  3. 11. The weak flexible upper layer of mantle on which the lithosphere moves
  4. 14. Small particles of rock and soil (sand is an example)
  5. 15. Thinnest, densest, iron rich crust that subducts on the ocean floor
  6. 18. A tectonic plate boundary where two plates collide or come together
  7. 21. magma that reaches Earth's surface
  8. 23. a naturally occurring, inorganic solid made of up one or more elements that has a crystal structure and a definite chemical composition
  9. 24. molten rock under the surface of Earth
  10. 25. The process by which sediments are pressed together under their own weight.
Down
  1. 1. The process in which dissolved minerals crystallize and "glue" particles of sediment together with water
  2. 2. Scientific scale that measures hardness of minerals
  3. 3. The breaking down of rocks and other materials on the Earth's surface.
  4. 5. process of weathering, wearing down, and movement of rock and soil by wind, water, or other natural agents.
  5. 6. The largest part of Earth’s interior, made of molten rock with convection currents
  6. 7. a type of rock that forms from the cooling of molten rock at or below the surface
  7. 9. the process that converts sediments into solid rock by compaction or cementation
  8. 10. rock that forms when sediments are compacted and cemented together
  9. 12. geologic process by which rock is formed and destroyed
  10. 13. A tectonic boundary where two plates slide past each other without creating or destroying crust (AKA strike-slip boundary)
  11. 14. The loose, weathered material on Earth's surface in which plants can grow (made up of silt, clay, sand, organic matter, water and air)
  12. 16. a combination of one in more minerals which have lithified, the type is named by how it forms
  13. 17. a type of rock that forms from an existing rock that is changed by heat and extreme pressure
  14. 19. Any substance that cannot be broken down into simpler substances
  15. 20. The innermost, densest part of earth interior, iron and nickel
  16. 22. Smallest particle of an element
