Answer:
the independent variable
Explanation:
The dependent variable "depends" on the independent variable.
Example:
I am measuring the growth speed of sunflowers under different types of light.
The growth speed of flowers "depends" on the type of light.
I will be deliberately changing the type of light being used to get different results for comparisons.
The type of light is the independent variable.

This is because these rocks have similar, if not the same layers, which can easily be determined by the fossils that may appear on them and just using them to match the layers to see if they can correlate.
