Relative dating superposition
Elicited student responses to the information on the handout should be followed by an explanation.
nderstanding of the geologic effects of Earthquakes on Earth’s strata, “The Geologic History of New York State” table in the “Earth Science Reference Tables”, electrophoresis, function and structure of the DNA molecule.
Related to their experiences with the inquiry based activity, a definition for relative dating and the Law of Superposition should be arrived at, and the official definition of horizontal stratigraphy, or the Law of Superposition, compared.
The important use of biotechnology in Earth Science should be elicited.
The method of reading the order is called stratigraphy (layers of rock are called strata).
Relative dating does not provide actual numerical dates for the rocks.
