Across 1. A MOUNTAIN CREATED PRIMARILY BY COMPRESSIONAL STRESS , WHICH CREATE FOLDS IN THE ROCK LAYERS. 6. A CRUSTAL BLOCK BOUNDED BY FAULTS, WHOSE GEOLOGIC HISTORY IS DISTINCT FROM THE HISTORIES OF ADJOINING CRUSTAL BLOCKS 8. THE PROCESS THAT COLLECTIVITY RESULT IN THE FORMATION OF MOUNTAINS 11. A LARGE STEPLIKE FOLD IN OTHERWISE HORIZONTAILSEDIMENTARY STRATA. 12. PROCESS OF ESTABLISHING A NEW LEVEL GRAVITATIONAL EQUILIBRIUM. 15. A FAULT IN WHICH THE MATERIAL ABOVE UP IN RELATION TO THE MATERIAL BELOW. 17. AN ELONGATED, UPLIFTED BLOCK OF CRUST BOUNDED BY FAULTS. 18. PROCESS THAT OCCURS WHEN CRUSTAL FRAGMENTS COLLIDE WITH AND STAY CONNECTED TO A CONTINENTAL PLATE. 19. THE CONCEPT TAHT EARTH'S CRUST IS FLOATING IN GRAVITATIONAL BALNCE UPON THE MATERIAL OF THE MANTLE

Down 1. A MOUNTAIN FORMED WHEN LARGE BLOCKS OF CRUST ARE TILTED, UPLIFTED, OR DROPPED BETWEEN LARGE NORMAL FAULTS. 2. THE FORCE PER UNIT AREA ACTING ON A SOLID. 3. A LINEAR DOWNFOLD IN SEDIMENTARY STRATA; THE OPPOSITE OF ANTICLINE. 4. THE CHANGE IN THE SHAPE OR VOLUME OF A BODY OF ROCK AS A RESULT OF STRESS. 5. A LARGE WEDGE-SHAPED MASS OF SEDIMENT THAT ACCUMULATES IN SUBDUCTING OCEANIC PLATE AND ACCRETED TO THE OVERRIDING CRUSTAL BLOCK. 7. GENERAL TERMSFOR THE PROCESSES OF FOLDING,FAULTING, SHEARING COMPRESSION, OR EXTENTION OF ROCKS AS THE RESULT OF VARIOUS NATURAL FORCES. 9. A FAULT ALONG WHICH THE MOVEMENT ID HORIZONTAL AND PARLLEL TO THE TREND OF THE FAULT . 10. A VALLEY FORMED BY THE DOWNWARD DISPLACEMENT OF A FAULT BOUNDED BLOCK 13. A REVERSE FAULT WITH A DIP LESS THAN 45 DEGREES, NORMALLY ABOUT 10-15 DEGREES. 14. A FAULT IN WHICH THE ROCK ABOVE THE FAULT PLANE HAS MOVED DOWN RELATIVE TO THE ROCK BELOW. 16. A FOLD IN SEDIMENTARY ATRATA RESEMBLING AN ARCH.
