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.

1. Radioactive dating can be compared to an hourglass, with the unstable chemical elements at the top.

2. Scientists compare parents and daughter elements in a rock to determine its age.

3. Potassium-argon dating is ideal for dating igneous and ancient rock.

What is radioactive dating?

Radioactive dating can be defined as a technique that is used to determine the age of both an organic and inorganic object, especially by measuring the amount of radioactive elements it contains.

Basically, radioactive dating is a technique that compares the relative abundance of a radioactive isotope (daughter elements) to a reference isotope (parent elements), in order to determine the age of both an organic and inorganic object.

The types of technique in radioactive dating:

Generally, there are different techniques adopted by scientists during radioactive dating and these include:

In conclusion, radioactive dating can be compared to an hourglass, with the unstable chemical elements at the top while the stable elements are at the bottom. Also, an ideal radioactive technique for dating igneous and ancient rock is potassium-argon dating because of its longer half-life.

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.

1.  Unstable

2.  Parents and daughter elements

3.  Igneous

4.  Ancient

Explanation:

There are two types of radioactive dating, which are potassium-argon dating (potassium-40) and carbon-14 dating.

While Pottasium 40 is used to date ancient rocks because it has a long half-life. Carbon-14 on the other hand, is used to date plant and animals because they contain some form of carbon-14.

Hence, Radioactive dating can be compared to an hourglass, with the UNSTABLE elements on the top. Scientists compare PARENTS AND DAUGHTER ELEMENTS in the rock to determine its age. Potassium-argon dating is ideal for dating IGNEOUS and ANCIENTrock.
