An overview discussion of craters and how they are used to date surfaces in the solar system as well as some of the caveats, complications, and limitations that go with the method. If a 1-km-diameter comet hits the moon, and a 1-km-diameter asteroid hits the moon, is the crater created by the asteroid likely to be larger, the same size, or smaller than the one created by the comet. Why or why not? Solution to Episode 39's Puzzler: The answer is pretty much a "Yes. This is contrary to what many creationists claim, such as the quote from Morris and Parker , "Now, the geologic column is an idea, not an actual series of rock layers.
What is the law of superposition and how can it be used to relatively date rocks?

History of Geology
Have you ever been to the Grand Canyon before? Relative dating and superposition of the Grand Canyon Rocks always tell a story. For instance, they reveal stories about colliding continents , meandering streams and volcanic eruptions. In the case of the Grand Canyon, the multi-layered strata provides insight to the age of the Earth. We are able to see cross-sections because the Colorado River started cutting through the Grand Canyon about 6 million years ago.
Relative and absolute ages in the histories of Earth and the Moon: The Geologic Time Scale
The law of superposition is that the youngest rock is always on top and the oldest rock is always on the bottom. The law of superposition is based on the common sense argument that the bottom layer had to laid down first. The bottom layer because it logically had to be laid down first must be older. The layers on top could only be laid down on top of the bottom layer so must be younger. However the relative ages of rocks is more commonly determined by the presumed ages of the fossils found in the sedimentary layers. The sedimentary layers with the simplest fossils are assumed to be older even if the sedimentary layer is found on top of a sedimentary layer that has fossils that are more complex and therefore assumed to be younger. Fossils that are in violation of the law of superposition where the older fossil occurs above a younger fossil are said to be stratigraphically disordered. The conclusion of some scientists is that the Law of Superposition just doesn't work Shindewolf Comments on Some Stratigraphic Terms American Journal of Science June " Historical geology relies chiefly on paleontology the study of fossil organisms.
The following chronological summary highlights some of the scientists, experimenters, theologians and thinkers of the past and how their ideas have contributed to our understanding of Earth's history. Herodotus BC observed that the Nile deposited silt during floods but believed most features were the result of sudden, violent processes.
The law of superposition is an axiom that forms one of the bases of the sciences of geology , archaeology , and other fields dealing with geological stratigraphy. It is a form of relative dating. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. This is important to stratigraphic dating , which assumes that the law of superposition holds true and that an object cannot be older than the materials of which it is composed.

A few days ago, I wrote a post about the basins of the Moon -- a result of a trip down a rabbit hole of book research. Here's the next step in that journey: In the science of geology, there are two main ways we use to describe how old a thing is or how long ago an event took place. There are absolute ages and there are relative ages. People love absolute ages. An absolute age is a number. When you say that I am 38 years old or that the dinosaurs died out 65 million years ago, or that the solar system formed 4. We use a variety of laboratory techniques to figure out absolute ages of rocks, often having to do with the known rates of decay of radioactive elements into detectable daughter products. Unfortunately, those methods don't work on all rocks, and they don't work at all if you don't have rocks in the laboratory to age-date. There's no absolute age-dating method that works from orbit, and although scientists are working on age-dating instruments small enough to fly on a lander I'm looking at you, Barbara Cohen , nothing has launched yet.

Academic journal article The Science Teacher. As our closest celestial neighbor, the Moon is a familiar and inspiring object to investigate using a small telescope, binoculars, or even photographs or one of the many high-quality maps available online see "On the web". The wondrously varied surface of the Moon--filled with craters, mountains, volcanic flows, scarps, and rilles--makes the Moon an excellent context for students to explore the methods scientists use to date geologic features, while learning about scientific observation and inference. This activity includes a unique application of the law of superposition that allows students to explore the relative ages of key lunar features and their origins. Even with an unaided eye, two types of terrain seem to dominate the Moon's surface: As on Earth, the different types of terrain on the Moon have different ages.
