Answer 5

radiocarbon dating is used to date
a) recent geologic events up to 10,000 years ago
b) all geologic events of the distant and recent past
c) recent geologic events up to 75,000 years ago
d) distant geologic events of 10 million years ago

Answer 6

In recent deposits so little decay has occurred that the error factor (the standard deviation) may be larger than the date obtained. The practical upper limit is about 50,000 years
