Radioactive decay has become one of the most useful methods for determining the age of formation of rocks. However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid. These assumptions include: 1 the initial amount of the daughter isotope is known, 2 neither parent or daughter product has migrated into, or out of, the closed rock system, and 3 decay has occurred at a constant rate over time. But what if one or some combination of these assumptions is incorrect? Then the computed age based on the accumulation of daughter products will be incorrect Stasson
Radiometric Dating — Is It Accurate?

The age of a rock is determined by stratigraphy , a branch in geology which studies the chronology of events and changes, along with the development of organisms, which have determined the development of the Earth from when it became an independent spatial body until today. The age, or the chronology of geological creations and events is determined using relative and absolute age. In determining the relative age of a rock, the data from sedimentary rocks are generally used. Relative age of magmatic and metamorphic rocks is determined according to their relation with sedimentary rocks. The determination of the relative age of a rock is based on the principle of original horizontality of the sediments, principle of superposition, principle of original lateral continuity, principle of cross-cutting relationships, principle of inclusions, principle of biological succession and the lithology of a rock.

This riddle exemplifies how time normally results in decay and destruction. So, why are people so interested in the topic of time? Perhaps the biggest reason is because of evil: how long can I put off dying? Humans have a limited lifespan to get things done, so we try to synchronize schedules in order not to waste time.
