Question

why is absolute dating more accurate than relative dating?
○ relative dating compares the placement of fossils on a large time scale.
○ absolute dating uses the half-life of an element.
○ relative dating uses the half-life of an element.
○ absolute dating uses more fossils than relative dating.

Explanation:

To determine why absolute dating is more accurate, we analyze each option:

• Option 1: Relative dating compares fossil placement (stratigraphy) for relative age, not a "large time scale" explanation of accuracy. Eliminate.
• Option 2: Absolute dating (e.g., radiometric dating) uses the half - life of radioactive elements to calculate the exact age of a sample. This provides a precise, numerical age, making it more accurate than relative dating (which only determines if one fossil/rock is older/younger than another).
• Option 3: Relative dating does not use half - lives; that is a method of absolute dating. Eliminate.
• Option 4: Absolute dating does not rely on using "more fossils" than relative dating. Eliminate.

Answer:

B. Absolute dating uses the half - life of an element.
