Geology Exam #4 Questions With Answers What is a parent isotope? A daughter? Parent Isotope: An isotope that undergoes decay to form a daughter isotope Daughter Isotope: May be stable or may decay to form another daughter (formed from the parent isotope) What is a half‐life? The time required for 1/2 of a radioactive isotope to decay ion a stable daughter isotope What is meant by mass wasting? The general term for all gravity induced movement of material down a slope. How a...

Geology Exam #4 Questions With Answers Mass wasting the downslope movement of rock, regolith, snow, or ice due to the pull of gravity Landslide a sudden movement of rock and debris down a nonvertical slope Soil creep the very slow, gradual movement of regolith downslope → driven by expansion and contraction cycles (freeze-thaw and wetting-drying) Failure surface A weak surface that forms the base of a landslide. Slump A semi-coherent volume of regolith that slipped do...
