RELATIVE DATING EXERCISE. Remember that relative dating involves determining "which Remember when we drew a topographic profile for lab manual exercise #1.

In the same way, such a transect could also show the inferred profile of the geology underfoot -- the expected rock layers and structures beneath the land from the northwest corner to the southeast corner of the map. Note that the first four answers are already given to you. If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata.

What principle s of relative dating did you use in order to arrive at your interpretation of the relative timing of each event? About About Scribd Press Our blog Join our team!

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.

Relative Dating Techniques Explained

Let's look at Block B. These major concepts are part of the Denver Earth Science Project's "Paleontology and Dinosaurs" module written for students in grades Return to top The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place. The only materials that start out with usable amounts of carbon in them are carbon-bearing materials which derived their carbon immediately from the atmosphere or from shallow water.

This means that the remains of living things are useful for carbon dating. For each of the relative dating diagrams, you are to think about them like the side view of a layer cake.

      Arrange them from oldest to youngest with the oldest layer on the bottom and the youngest on top. Which layering shown in the figure demonstrates disconformity?

      Examine the geologic cross sections which follow, and determine the relative ages of the rock bodies, lettered features such as faults or surfaces of erosion, and other events such as tilting, folding, or erosion events.

      To review our principles of relative dating as applied to such geologic cross-sections, we will make use of a neat learning tool available on the Internet.
