Based on a schematic diagram of an outcrop provided in the first question, students are asked to list the relative ages of the four different rock units and provide the reasoning behind their interpretation based on the principles of relative age and the processes involved in the formation of each rock. Students are told that there are two possible solutions and must describe both. The second part of question one asks students to describe the geologic evidence they would look for in the outcrop to determine which of the solutions was likely correct. The second question of the assignment is about numerical age dating. Students are asked to list what could be dated in each rock (e.g. minerals, fossils) and which particular process during the formation of each rock would be dated in doing so.
