use the drop - down menus and what you have learned about potassium - argon dating to complete the sentences. radioactive dating can be compared to an hourglass, with the elements on the top. scientists compare in the rock to determine its age. potassium - argon dating is ideal for dating and rock.
Answer
Brief Explanations:
Radioactive dating uses the decay of radioactive elements. In potassium - argon dating, radioactive potassium decays to argon. Scientists compare the ratio of parent (potassium) to daughter (argon) elements in rocks. It is ideal for dating igneous and metamorphic rocks as they form under conditions where the initial argon content can be assumed to be known or negligible.
Answer:
- the ratio of parent and daughter elements
- radioactive
- igneous
- metamorphic
