As we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects. In other words, you can use superposition to tell you that one rock layer is older than another. To accomplish this, scientists use a variety of evidence, from tree rings to the amounts of radioactive materials in a rock. In regions outside the tropics, trees grow more quickly during the warm summer months than during the cooler winter.
Each dark band represents a winter; by counting rings it is possible to find the age of the tree Figure The width of a series of growth rings can give clues to past climates and various disruptions such as forest fires. Droughts and other variations in the climate make the tree grow slower or faster than normal, which shows up in the widths of the tree rings. These tree ring variations will appear in all trees growing in a certain region, so scientists can match up the growth rings of living and dead trees.
Using logs recovered from old buildings and ancient ruins, scientists have been able to compare tree rings to create a continuous record of tree rings over the past 2, years. This tree ring record has proven extremely useful in creating a record of climate change, and in finding the age of ancient structures. Figure

Geologic Time. From the beginning of this course, we have stated that the Earth is about 4. How do we know this and how do we know the ages of other events in Earth history? Prior to the late 17th century, geologic time was thought to be the same as historical time. The goal of this lecture is come to come to a scientific understanding of geologic time and the age of the Earth. In order to do so we will have to understand the following:. In order to understand how scientists deal with time we first need to understand the concepts of relative age and numeric age.
By carefully digging, we have found that each trash pit shows a sequence of layers. Although the types of trash in each pit is quite variable, each layer has a distinctive kind of trash that distinguishes it from other layers in the pits. Notice that at this point we do not know exactly how old any layer really is. Thus we do not know the numeric age of any given layer. Stratigraphy is the study of strata sedimentary layers in the Earth’s crust.
Geologist in the s worked out 7 basic principles of stratigraphy that allowed them, and now us, to work out the relative ages of rocks. Once these age relations were worked out, another principle fell into place – the principle of fossil succession.
