In other words, it represents what the rock layers would look like if you took a knife and sliced down through the Earth at a given location, like a piece of cake. Note that all three types of rock sedimentary, metamorphic, and igneous are present in this cross section. Note how the ages of the rock decrease in age from the bottom to the top. Listen to scientists talk about the age of the Grand Canyon and the controversy over the dating.
Press the play button on the left of the page to listen. Transcripts available on the left menu as well. How Old is the Grand Canyon? Grand Canyon May be Older and Younger than you think. Check out Basic Answers to your Geologic Questions. You will be determining the relative order in which geological events occurred, as shown in this generic stratigraphic cross section below. Stratigraphy is the study of the rock strata, or layers, and is usually applied to sedimentary and sometimes volcanic rocks.
Step 1: Start with the oldest rock. It is best to tell the story of what happened in the cross section by trying to find the thing that happened first rather than starting with the last thing that happened. In this case, we see that layer C is the oldest because it is on the bottom. Step 2: List out the story of events and rocks. Include events like folding, faulting, and erosion in your story.
Step 3: List the letters in the order in which they occurred. Start at the bottom oldest and list to the youngest event. Step 4: Check your logic. Use the principles of relative age dating to make sure the order makes sense.

Amino acid dating: Physical structure of living beings depends on the protein content in their bodies. The changes in this content help determine the relative age of these fossils. Dendrochronology: Each tree has growth rings in its trunk. This technique dates the time period during which these rings were formed. Thermoluminescence: It determines the period during which certain object was last subjected to heat.
It is based on the concept that heated objects absorb light, and emit electrons. The emissions are measured to compute the age. A Venn diagram depicts both dating methods as two individual sets. The area of intersection of both sets depicts the functions common to both. Take a look at the diagram to understand their common functions. When we observe the intersection in this diagram depicting these two dating techniques, we can conclude that they both have two things in common:.
Provide an idea of the sequence in which events have occurred. Determine the age of fossils, rocks, or ancient monuments. Although absolute dating methods determine the accurate age compared to the relative methods, both are good in their own ways. Force applied per unit area of any surface is called pressure. Absolute pressure refers to the measurement of pressure at absolute zero, whereas gauge pressure refers to the measurement of….

If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic. Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed. Correlation can involve matching an undated rock with a dated one at another location.
Suppose you find a fossil at one place that cannot be dated using absolute methods. That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age. Some of the most useful fossils for dating purposes are very small ones. For example, microscopic dinoflagellates have been studied and dated in great detail around the world.
Correlation with them has helped geologists, such as Professor James Crampton , date many New Zealand rocks, including those containing dinosaurs. Bring relative dating principles to life with the activity Rock layers and relative dating. Students begin by observing a photograph and a diagram of rock layers near Whanganui, watch an animation about how the layers were formed , then use an interactive labelling diagram to work out the order in which the rocks were created.
