Question

Radiometric dating of a sedimentary rock sample shows an age of 1.5 million years. What conclusions can be drawn from this data? Radiometric dating cannot be used on sedimentary rock so no conclusions can be drawn. The rock is a minimum of 1.5 million years old but it may be older. The rock is exactly 1.5 million years old. The rock is a maximum of 1.5 million years old but it may be younger.

Answer 1

The correct answer should be the option - "The rock is a minimum of 1.5 million years old but it may be older"

Radioactive dating, also known as Radioisotope dating is a process that helps in estimating the approximate age of rocks. These data can be analyzed from the studies dealing with the decay of the radioactive elements that are present in these rocks.

In nature, there are a few types of materials or atoms which are quite unstable and they spontaneously decay or breakdown to form other kinds of atoms.
