Practice question · Estimate
A pollen core is sampled every centimeter, and peat here accumulates about 1 mm per year. Roughly how many YEARS does each 1 cm sample average over? Set the slider.
Estimate on a scale from 0 yr (0) to 50 yr (50).
Hints
- 1 cm = 10 mm; at 1 mm/year…
- Each sample blurs together about a decade.

Why
About 10 years per centimeter, so even a fine core averages roughly a decade into each sample. Proxy resolution is set by accumulation rate; you cannot read a single year from slow peat.
