Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.Cosmic rays enter the earth's atmosphere in large numbers every day and when one collides with an atom in the atmosphere, it can create a secondary cosmic ray in the form of an energetic neutron.As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.Carbon dating uses an exponential decay function, remaining in an object that is t years old.In other words, this function takes in a number of years, t, as its input value and gives back an output value of the percentage of carbon-14 remaining.Conversely, the method doesn't work on objects that are too young.This method also cannot apply to the remains of aquatic life, because doesn't enter the ocean at an amount substantial enough for proper analysis.
