Which type of scientific statement is defined as a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable?

Hypothesis

Explanation:

HYPOTHESIS  is the explanation of things or specific questions, or answers  that is of known knowledge or research that is testable

It can also be a preposition or an assumption  that tries to explain some set of evidence or known facts in an established way.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
