Begin by reviewing the Stratigraphy Map provided, which outlines layers A-G. Familiarize yourself with the artifacts numbered 1-9.
In the first section, answer questions comparing artifacts, such as determining which is older: the arrowhead or the spear point. Use the Law of Superposition as your guide.
Proceed to analyze each layer's context. For example, if layer G is a well, hypothesize who might have dug it based on surrounding artifacts.
Continue answering questions about the age of layers and presence of humans during their formation. Support your answers with evidence from the artifacts listed.
Finally, review your responses for clarity and completeness before saving or sharing your completed form.

stratification, the layering that occurs in most sedimentary rocks and in those igneous rocks formed at Earths surface, as from lava flows and volcanic fragmental deposits. The layers range from several millimetres to many metres in thickness and vary greatly in shape.
What is an example of using stratigraphy?
An example of a stratigraphic profile, courtesy of Crow Canyon Archaeological Center. Stratigraphy allows us to relatively date each layer of soil based on the artifacts found in each stratum. This helps us understand the chronological sequence of events.
How is stratigraphy dating done?
Stratigraphy. The main principle behind stratigraphy is that of superposition. This says that older things are found below younger things. When archaeologists excavate sites, we find layers of soil, each marking a period of use of the site.
What are the 7 laws of stratigraphy?
Stratigraphic Principles Principle of Original Horizontality. Principle of Superposition. Principle of Lateral Continuity. Principle of Fossil Succession. Principle of Inclusions. Principle of Cross-Cutting Relationships. Walthers Law. Unconformities.
What does stratigraphy mean?
Stratigraphy is a branch of Geology and the Earth Sciences that deals with the arrangement and succession of strata, or layers, as well as the origin, composition and distribution of these geological strata. The study of archaeological and natural stratification therefore involves the assessment of TIME and SPACE.
