1. the supercontinent that existed before continents separated
4. the movement caused within a fluid when the hotter, less dense material rises, and colder denser material sinks
5. when magma flows through a crack in the middle of a tectonic plate and not at a plate boundary hawaiian islands were formed this way
9. when a sudden release of energy in the lithosphere creates seismic waves
11. the lower part of earth's mantle, below the asthenosphere
13. boundary where tectonic plates slide past eachother
15. form at convergent boundaries where on plate subducts under another and magma undergroundis pushed upwards
16. the outer part of the earth includes the crust and upper mantle

2. below the lithosphere, hotter and more fluid part of the mantle
3. boundary where tectonic plate collide
6. large pieces of lithosphere that the ocean and continents rest on
7. boundary where tectonic plates divide
8. the layer that lies between earth's crust and core. the majority of earth's mass is in this layer
10. the solid, outermost layer of the earth, lying above the mantle
12. occurs when divergent plates separate convection currents cause less dense material to rise creates new ocean floor
14. the innermost layer of earth. divided into two parts liquid outer and solid inner made of iron and nickel
