The architecture of geological time includes ages, epochs, periods, & eras, which index fossils helped to determine. It is found in sedimentary rocks, asphalt deposits, coal, amber and other materials. In this idea, pre-biological changes slowly transform simple atoms and molecules into the more complex chemicals needed to produce life. x(t)=(7.40cm)cos[(4.16rad/s)t2.42].
