Across
  1. 4. – molten rock (magma) that has reached the Earth’s surface
  2. 7. drift – the slow movement of the Earth’s landmasses
  3. 9. – the breaking down of minerals and rocks into small sediments (wind, water, ice, and chemical reactions cause weathering)
  4. 10. rock – formed when magma cools and hardens
  5. 11. – a fan shaped sediment deposit formed at the mouth of a river
  6. 12. Boundary – where plates are moving apart (creates mid-ocean ridges)
  7. 16. rock – hard matter formed by extreme heat and pressure deep within the Earth
  8. 20. – an ancient landmass believed to have broken up into today’s continents
  9. 21. boundary – where plates are pushed together creating mountains & volcanoes
  10. 22. – a process in which wind, water, and gravity leave eroded sediments in new locations
Down
  1. 1. (transform) boundary – where plates are sliding past each other
  2. 2. – a location where one of the Earth’s plates meets another
  3. 3. core – the layer of the Earth made of liquid iron and nickel just below the mantle
  4. 5. core – the center region of the Earth made of solid iron and nickel
  5. 6. – the middle layer of the Earth made of melted rock
  6. 7. – the outer layer of the Earth made of solid rock
  7. 8. rock – formed when layers of sediment are pressed together
  8. 13. – a shaking movement of the ground caused by a sudden shift of the Earth’s crust
  9. 14. – hot, melted rock that makes up the Earth’s mantle
  10. 15. – a mountain with vents where lava, gases, and ash erupt
  11. 17. – the moving away of sediments caused by wind, ice, and WATER
  12. 18. Tectonics- a theory that the Earth’s crust is broken into distinct pieces
  13. 19. – the remains of an organism that lived in the past (cast, mold, and imprint fossils)
