Introduction

Lines of latitude (parallels) run east-west and increase from 0° at the Equator to 90°at the poles. The Equator represents the center of the Earth, where the sun appears to pass directly overhead on the spring and fall equinoxes. The Earth bulges slightly at the equator. Lines of latitude are spaced equally apart and never intersect (ES.3).

How Carbon-14 Dating Works | HowStuffWorks

 · A formula to calculate how old a sample is by carbon-14 dating is: t = [ ln (Nf/No) / (-0.693) ] x t1/2. t = [ ln (N f /N o) / (-0.693) ] x t 1/2. where ln is the natural logarithm, N f /N o is the percent of carbon-14 in the sample compared to the amount in living tissue, and t 1/2 is the half-life of carbon-14 (5,700 years).. So, if you had a fossil that had 10 percent carbon-14 compared to ...
