You do not need to complete the second half of this particular exercise (about resolving these ambiguities in the relative dating).
Question 4 (3 points): What is the sequence of events that can be inferred from the above cross-section?
Along with these geologic maps, we can reconstruct a regional geologic cross-section which would be like a great "geologic slice" through the landscape.
Cliffs, road cuts, and non-vegetated landscapes allow us glimpses into geology which is often hidden from view.
Cliffs and road cuts are "side views" or "geologic cross-sections" of the topography which show the relative positions of various rock layers and structures at a given spot.
Click Question 1 (3 points): Find the list of hypothetical geologic examples and click on "fault." We are asked to determine the correct sequence of geologic events shown by the cross-section.
In order to do this, we need to apply the principles of relative dating which we have learned.
Complete the sequence correctly and explain the logic and principle behind your choice for each event.
Your explanations are as important as the correct sequence in earning the points for this question.What principle(s) of relative dating did you use in order to arrive at your interpretation of the relative timing of each event?The various sedimentary layers are labeled as B, E, K and W.To review our principles of relative dating as applied to such geologic cross-sections, we will make use of a neat learning tool available on the Internet."Athro Limited" is a private company which provides education modules on the Internet.Notice that the various sedimentary layers have been labeled with letters.
