  1. 1. State of matter that is like a solid and a liquid; moves very slowly
  2. 3. Hot, melted rock that is below the surface of Earth
  3. 5. The thinner crust found underneath the earth’s oceans.
  4. 8. The state of matter for the inner core and lithosphere.
  5. 11. To float or lift; what hot fluids do
  6. 12. A process that happens in fluids if they are hotter at the bottom and colder at the top
  7. 14. The thicker crust that makes up the earth’s continents.
  8. 16. The state of matter of Earth’s outer core; a type of fluid
  9. 18. When molecules in a substance are closer together.
  10. 19. The innermost compositional layer of Earth; made of melted and solid metal.
  11. 21. The middle compositional layer of Earth; made of melted rock that moves slowly

  1. 2. When molecules in a substance are more spread out.
  2. 4. The semi-solid mechanical layer of Earth made of melted rock that moves slowly (part of the upper mantle)
  3. 6. Hot, melted rock that is above the surface of Earth (from volcanoes)
  4. 7. What the inner core and outer core are made of.
  5. 8. To drop or fall; what cold fluids do
  6. 9. The outer mechanical layer of Earth made of solid rock (includes the crust and upper mantle)
  7. 10. The outermost compositional layer of Earth; the solid layer we live on top of.
  8. 13. A substance that can flow and change its shape, such as a liquid or gas.
  9. 15. Mechanical layer of Earth where convection currents form in liquid metal and create a magnetic field
  10. 17. A circular pattern that forms when hot fluids rise, get cold, sink, and repeat.
  11. 20. What the crust and mantle are made of
