Question

1. carbon-14 dating can be used to find the age of which of the following materials?

○ copper
○ shale
○ granite
○ wood

Explanation:

Carbon-14 dating only works on once-living organic materials, as it relies on measuring the decay of carbon-14 absorbed during an organism's lifetime. Wood is organic (from once-living trees), while copper, shale, and granite are inorganic non-living substances that cannot be dated with this method.

Answer:

○ wood
