The half-life of a radioactive element is the length of time it takes for half of a given amount of the element to break down, or decay.
Question 1 options:
True
False
The half-life of carbon-14 is 5730 years. Radiocarbon dating can not be used to estimate the age of objects up to about 50,000 or 60,000 years old.
Question 2 options:
True
False
The amount of a radioactive element remaining in an object is measured. Based on the known half-life of the element, the amount remaining can be used to calculate how old the object is.
Question 3 options:
True
False
Radiometric dating can give the exact age of an object
Question 4 options:
True
False
Different isotopes are used to find the age of artifacts older than 60,000 years.
Question 5 options:
