Across
  1. 3. the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere.
  2. 6. a separation process in which a certain quantity of a mixture (of gasses, solids, liquids, enzymes, or isotopes, or a suspension) is divided during a phase transition, into a number of smaller quantities (fractions) in which the composition varies according to a gradient.
  3. 7. area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma.
  4. 10. temperature
  5. 13. and silicon
  6. 14. lowest melting temperature of a mixture of two or more components
  7. 15. zones
  8. 17. forms when an oceanic plate sinks beneath another plate, releasing fluids that melt minerals and generate magma
  9. 18. rock that forms deep within the Earth
  10. 22. melting
Down
  1. 1. of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another.
  2. 2. gases that can easily vaporize, such as water (H2O) and carbon dioxide (CO2)
  3. 4. the upward movement of Earth's mostly solid mantle
  4. 5. convection
  5. 8. when water or carbon dioxide are added to rock
  6. 9. melting
  7. 11. composition
  8. 12. rocks are heated to temperatures above their melting point, some minerals within the rock melt first
  9. 16. Melting
  10. 19. happens at convergent boundaries, where tectonic plates are crashing together.
  11. 20. magma solidifies in the air to form volcanic rock called
  12. 21. transfer melting
