- Q10If an igneous intrusion is observed through a layer of sedimentary rock, what geological law applies?law of thermodynamicslaw of superpositionlaw of crosscutting relationshipslaw of uniformitarianism30s
- Q11. the principle that geologic processes that occurred in the past can be explained by current geologic processesuniformitarianismsuperpositionunconformitycross-cutting relationships30s
- Q12Which of the following are all ways that organisms can be fossilized?amber, petrification, mummification, freezingdesiccation, petrification, mummification, amberfreezing, petrification, desiccation, ambermummification, desiccation, petrification, freezing30s
- Q13Why are rates of erosion and deposition not reliable for dating very old rock formations?average rates of erosion and deposition change too much over long periods of timeThere is no way to calculate these ratesThey are completely reliableErosion and deposition did not occur in the distant past30s
- Q14The fixed rate at which radioactive elements will decay by half their abundance.varve ratehalf-lifelaw of superpositionrate of deposition30s
- Q15Why are fossils relatively rare?Fossils can only form in dry environmentsorganisms must be trapped in tar to become a fossilthey must be mummified to become a fossilmost organisms decay after death30s
