I had trouble with a question in my Science Probe 10 Text book On Review 12.1 (Chapter Name: Geological Time). The Question is:
Why is it fairly easy to estimate the absolute age of some objects but not of some others? Describe how these types of objects might be different.
Can someone please help me on this question? Thanks.

Because variables exist in life. Weather can
cause problems in calculating the age of things like
trees and land.
