Too little heat results in the corn partially steaming, producing soggy kernels instead of crunchy ones.Determining the age of the ash layer will reveal the age of the surrounding ice.Geologists take advantage of decay of natural radioactive elements to determine the age of rocks, which can help us understand earth history.The time that it takes for half of the isotope of K to form Ar is called the “half life,” which in the case of K-Ar is 1.25 billion years.By measuring the ratio of K to Ar in feldspar crystals in ash from a volcanic eruption, the age of the eruption, and therefore the age of the ice in which the ash is found, can be determined.
