2. Convection current The transfer of thermal energy by the circulation or movement of a liquid or gas.

3. P-waves A seismic wave that can travel through a liquid and a solid. The p stands for primary.

4. S-waves A seismic wave that can travel only through solids. S-stands for secondary wave.

5. Crust The thinnest layer of the Earth. It is the top layer on which we live on.

6. Mantle The layer of rock between the earth’s crust and core.

7. Inner core The solid, inner most layer of the earth. It is made up of iron and nickel.

8. Waves of energy that travel through the Earth and away from an earthquake in all directions. Seismic waves

9. Continental crust The layer of igneous, sedimentary, and metamorphic rock which form the continents.

10. Oceanic crust The part of earth’s lithosphere that surfaces in the ocean basins.

11. The liquid layer of earth that is between the lower mantle and inner core. Outer Core
