24. Which condition produces the greatest earthquake hazard for a structure? a. fundamental period of foundation soil fundamental period of structure fundamental period of foundation soil-fundamental period of structure none of the above c. d. 25. The mechanical and chemical breakdown of rocks on the surface of the earth into smaller particles that may differ from the original substance is known as: a. erosion b. diagenesis c. weathering d. none of the above 26. Which of the following are mechanisms of salt weathering? a. b. c. d. pressure produced by growing salt crystals pressure produced by thermal expansion of salt crystals pressure produced by water absorption and expansion of hydrated salt crystals all of the above 27·The movement of water within narrow pathways in a rock or soil caused by the molecular attraction of the rock or soil is known as? a hydration b. adsorption c. capillary action d. convection 28. Which of the following minerals has the lowest solubility? a. calcite b. halite c. quartz d. gypsum 29. The level of the potentiometric surface in a piezometer measuring head in a confined aquifer: a. defines the top of the water table b. is above the aquifer c. cannot be determined without a second test well in the area d. none of the aboveExplanation / Answer
24.option c= fundamental period of foundation soil = fundamental period of structure
this situation result in maximum earthquake hazard
25. option c=weathering
weathering means breakdown of rocks into smaller pieces through contact with earth's atmosphere and the resultant particles may differ from original substance
26 option d- all of the above
27.option c =capillary action
capillary action is the movement of liquid along a surface of a solid caused by the attraction of molecules of the liquid to the molecules of the solid.
