4. A CONCENTRATION OF HEAT IN THE MANTLE CAPABLE OF CREATING MAGMA
6. A CHAIN OF VOLCANOES THAT DEVELOP PARALLEL TO A TRENCH
8. A BOUNDARY PRODUCED WHEN TWO PLATES SLIDE PAST EACH OTHER
11. THE SCIENCE THAT STUDIES EARTH
16. THE OUTER PORTION OF THE EARTH
17. A BOUNDARY TWO PLATES MOVE TOWARD EACH OTHER CAUSING ONE OF THE SLABS OF THE LITHOSPHERE TO SUBDUCT BENEATH AN OVERRIDING PLATE
20. ANY BREAK IN A ROCK IN WHICH NO SIGNIFICANT MOVEMENT HAS TAKEN PLACE
21. CONSOLIDATED MIXTURE OF MATERIALS
22. A THEORY WHICH SUGGESTS THAT THE EARTH'S CRUST IS MADE UP OF PLATES THAT INTERACT IN VARIOUS WAYS THUS PRODUCING EARTHQUAKES, MOUNTAINS, VOLCANOES AND OTHER GEOLOGIC FEATURES

12. THE FIRST TYPE OF SEISMIC WAVE TO BE RECORDED IN A SEISMIC STATION
13. A DEPRESSION IN THE SEAFLOOR PRODUCED BY SUBDUCTION PROCESS
14. RIGID SECTIONS OF THE LITHOSPHERE THAT MOVES AS A VENT
15. A BREAK IN A ROCK ALONG WHICH MOVEMENT HAS OCCURED
18. VIBRATION OF EARTH DUE TO RAPID RELEASE OF ENERGY
19. THE THIN PART OF THE EARTH'S CRUST LOCATED UNDER THE OCEANS
