Answer to Question 1

Answer: Stress is the magnitude of a force applied over an indicated area, and strain is the measure of the amount of deformation that results from the stress. Rock strength is the amount of stress that the material can endure before it strains. When applied stress exceeds the strength of a rock, the rock deforms by folding, faulting, or flowing. Compressive stress shortens rocks parallel to the stress direction, whereas tensional stress elongates rocks. Shear stress moves materials in opposite directions without shortening or elongation.

Answer to Question 2

Answer: TRUE

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
