Across
- 3. the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere.
- 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.
- 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.
- 10. temperature
- 13. and silicon
- 14. lowest melting temperature of a mixture of two or more components
- 15. zones
- 17. forms when an oceanic plate sinks beneath another plate, releasing fluids that melt minerals and generate magma
- 18. rock that forms deep within the Earth
- 22. melting
Down
- 1. of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another.
- 2. gases that can easily vaporize, such as water (H2O) and carbon dioxide (CO2)
- 4. the upward movement of Earth's mostly solid mantle
- 5. convection
- 8. when water or carbon dioxide are added to rock
- 9. melting
- 11. composition
- 12. rocks are heated to temperatures above their melting point, some minerals within the rock melt first
- 16. Melting
- 19. happens at convergent boundaries, where tectonic plates are crashing together.
- 20. magma solidifies in the air to form volcanic rock called
- 21. transfer melting
