Radioactive dating can be likened to an hourglass, with the ________ elements placed atop. In order to assess the age of the rock, scientists make comparisons of the ________ within it. Potassium-argon dating is suited for analyzing _________ and _______ rock.

Answer:

1. Unstable

2. Parent and daughter isotopes

3. Igneous

4. Ancient

Explanation:

Radioactive dating includes two primary methods: potassium-argon dating (utilizing potassium-40) and carbon-14 dating.

Potassium-40 is particularly beneficial for dating ancient rocks due to its lengthy half-life, whereas carbon-14 is applicable for determining the age of plants and animals as they incorporate a form of carbon-14.

Thus, radioactive dating can be visualized as an hourglass with the UNSTABLE elements positioned at the top. Scientists analyze the PARENT AND DAUGHTER ISOTOPES present in the rock to ascertain its age. Potassium-argon dating is optimal for dating IGNEOUS and ANCIENT rock.

marta [418]

Answer:

When the Constitution was drafted, the thirteen states needed to endorse it for it to come into effect, as the US operates as a federal republic.

Explanation:

This was contentious because antifederalists believed a national government was excessively powerful.

The Articles of Confederation were initially intended to serve as our governing framework, but they rendered the government too feeble, so the Constitution replaced it despite ongoing opposition from the antifederalists.

Essentially, the question prompts you to choose between supporting the constitution and a federal system or opposing it as the antifederalists did.
