PURPOSE AND OBJECTIVES
5) To use radiometric dating and the principles of determining relative age to show how ages of rocks and fossils can be narrowed even if they cannot be dated radiometrically. Each team of 3 to 5 students should discuss together how to determine the relative age of each of the rock units in the block diagram ( Figure 1). 14 Nov Therefore, from top to bottom, the rocks provide a continuous record of more than billion years of geological history in this region. Q: How have scientists been able to determine the ages of rocks in the Grand Canyon? A: The ages are based on the gradual decay, or break down, of radioactive isotopes. Background: Relative dating gives an approximate age of something compared to some other event in history. Scientists can tell that the item is “older” or “ younger” than certain events in time, but cannot give an exact age of the item. Relative dating is common when comparing layers of rocks in different regions, and figuring.

- Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil? The study of strata is called stratigraphy, and using a few basic principles, it is possible to work out the relative ages of rocks. Individual rock layers, or strata, can be seen exposed in the wall of the. Figure 1: .

- Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. layers, they can figure out the youngest and oldest that the fossil might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur.

Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4. Recent research shows otherwise.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as true information. Far from being data, these dates are literally interpretations of the data.
