Question

can change into the form of aa through it's process, however aa cannot change to pahoehoe. Aa has surfaces that are opposite of the smooth pahoehoe, they are rougher with sharp jagged edges of blocks, both are slow moving basaltic (Fredrick K. Lutgens, 2014). References Fredrick K. Lutgens, E. J. (2014). Foundations of Forth Science, Seventh Edition. In your own words, compare and contrast relative age dating with radiometric dating. What are the strengths and limitations (if any) of each? Reference USGS (2001). Your response should be at least 200 words in length.

Explanation / Answer

Relative dating is less precise than radiometric dating. When you use radiometric dating, you get a numeric answer... for instance, you may find that a rock is 230 million years old through radiometric dating. In relative dating, you use other clues to estimate the relative age of the rock. For instance, if a rock is in a layer that is in between Triassic and Cretaceous rock layers, you could assume the rock is Jurassic in age. The drawback to relative dating is that it is not very precise. A limitation of radiometric dating is that certain elements must be present, and radiometric dating just isn't a good option in some situations.
