Final answer:
Geologists can determine the absolute age of rocks and landforms by studying rates of erosion over time.
Step-by-step explanation:
Geologists can use rates of erosion to help determine the absolute age of rocks and landforms over time.
By studying the erosion rates of different rocks and landforms, scientists can estimate how long it took for them to form.
For example, if a particular rock formation has been eroded at a constant rate and has a known thickness of eroded material, scientists can calculate the age of the formation by dividing the thickness by the erosion rate.
