Across
- 2. a layer of solid rock that surrounds the Earth's surface
- 4. the thick layer that surrounds the core and is made up of hot but mostly solid material
- 6. plate thick plates made of andesite and granite that form the continents and are less dense than oceanic plates
- 7. tectonic plates Juan de Fuco Plate, Nazca Plate, Philippine Plate, Caribbean Plate, Scotia Plate, Arabian Plate, and Cocos Plate
- 9. topmost layer of the Earth made up of the crust and the solid portion of the upper mantle
- 12. the supercontinent
- 14. of plate tectonics scientific theory explaining how the plates move on the Earth's surface
- 15. plate occurs when two plates move towards each other and collide
- 16. plate occurs when two plates move away from each other
Down
- 1. plate thin plates that are made of basalt that form the ocean floor and are denser than continental plates
- 3. plates Earth's surface is broken into large pieces that move over the asthenosphere
- 5. where the plates of the lithosphere float, or slide a top, a thin, semi-solid layer in the upper mantle
- 8. plate occurs when two plates slide past each other
- 10. tectonic plates Eurasian Plate, North American Plate, South American Plate, Pacific Plate, African Plate, Australian Plate, Antarctic Plate, and Indian Plate
- 11. core liquid metal that surrounds the inner core
- 13. currents caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again, and then heating, rising, and repeating the cycle over and over
- 17. core a sphere of hot, solid metal
