Tcap review

2. The innermost layer of earth. Divided into 2 parts, liquid outer and solid inner. Made of iron and nickel.
3. plates large pieces of lithosphere that the ocean and continents rest on.
5. floor spreading occurs when divergent plates separate. convection currents cause less dense materials to rise. creates new ocean floor.
8. The solid, outermost layer of the earth, lying above the mantle
9. Boundary Boundary were tectonic plates divide.
10. Spot 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.
11. the supercontinent that existed before continents separated.
12. the layer that lies between Earth's crust and core. The majority of earths mass in this layer

1. Form at convergent boundaries where one plate subducts under another, and magma underground is pushed upward.
4. boundary Boundary were tectonic plates collide.
6. when a sudden release of energy in the lithosphere creates seismic waves.
7. boundary Boundary were tectonic plates slide past each other.
