Q:
Assuming that humans went extinct today, do you think that they would be good index fossils? Why or why not?
Q:
You are studying an outcrop where the base layer is limestone and the layer directly on top of that is sandstone. Near the base of the sandstone are small, weathered pieces of limestone entirely contained within the sandstone. Explain how these pieces of limestone came to be contained within the sandstone.
Q:
One method of geologic dating is dendrochronology, or the science of tree ring dating. Based on what you know about tree rings, how could you determine the age of the tree? Would this be an example of relative dating or numerical dating?
Q:
