Question

Assertion: The age of the earth has been estimated by Uranium dating technique.

Reason: Uranium dating is based on evidence from radiometric age dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

The age of earth has been estimated by $Uraniumdating$ technique. This dating is based on evidence from radiometric age dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples. Uranium–lead $(U–Pb)$ dating is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed from about $1$ million years to over $4.5$ billion years ago with routine precisions in the $0.1–1$ percent range.
