Question

3: Hominids are the group of primates that includes humans, gorillas, and chimpanzees. In 1997 a team of scientistsdiscovered three fossilized hominid skulls and other artifacts found at the dig site in Ethiopia. Since it is difficult todetermine the age of once living organisms, the scientists used radioactive dating on the igneous rock thatsurrounded the remains to determine their age.
Why would scientists choose radioactive dating to determine the age of the igneous rock?

A: This method is an easier way to determine the age of rocks.
B: The procedure allows for the rock samples to be preserved.
C: This process provides scientists with the exact age of rocks.
D: The rate of decay in the rock provide an accurate way to calculate age.

Answer 1

C: This process provides scientists with the exact age of rocks.

Explanation:

Radioactive dating techniques are absolute dating methods that yields precise age of rocks. They are targeted at radioactive isotopes in rocks using their parent to daughter ratio.

• Dating can either be absolute or relative
• Absolute dating techniques like radiometric ones gives the precise age of rocks.
• Relative dating techniques uses geologic events to place the age of earth samples.
• When the scientist deploys radioactive measurement, he would be furnished with actual age of the rock.
